2 Intuitionistic Fuzzy Sets

Due to the complexity and uncertainty of candidates somecriteria are more suitable for evaluation in linguistic formThe linguistic terms are mostly modeled with triangularfuzzy number [15 16] Afterwards intuitionistic fuzzy sets areproposed to model the linguistic terms [17] Compared withfuzzy sets which only consider the degree of membershipintuitionistic fuzzy sets is characterized by both a member-ship function and a nonmembership function and the sum ofboth values is allowed to be less than one [18] It has been usedsuch as in the area of search algorithm selection [19] RuralLogistics Center Location [20] information system projectselection [21] and green supply chain [22] In the followingintuitionistic fuzzy sets are reviewed briefly [17 18 23ndash25]

Definition 1 (see [17]) Let X be a given finite set then definean intuitionistic fuzzy set on X as A

in which 120583119860 119883 997888rarr [0 1] and V119860 119883 997888rarr[0 1] are respectively the membership function and thenonmembership function with the condition 0 le 120583119860(119909) +V119860(119909) le 1

In addition 120587119860(119909) = 1 minus 120583119860(119909) minus V119860(119909) represents theintuitionistic fuzzy index or hesitancy degree of whether 119909belongs to 119860 or not with the condition 0 le 120587119860(119909) le 1Definition 2 (see [18]) Arithmetic operations on intuitionis-tic fuzzy numbers

(5) 120572120573 = (min (120583119860 120583119861) max (V119860 V119861)) (6)

Definition 3 (see [25]) For intuitionistic fuzzy numbers thescore function of 120572 is defined as

119904 (120572) = 119896120583120572 minus 119896V120572 + (1 minus 2119896) 10038161003816100381610038161 minus (120583 + V120572)1003816100381610038161003816 (7)

where k reflects the decision attitude of the evaluator and 0 lt119896 lt 1

Definition 4 (see [24]) Entropy for intuitionistic fuzzy num-bers is as follows

3 Evaluation Criteria of the Risk of NaturalGas Pipeline Operation Management

Natural gas is a national strategic resource and its prod-uct characteristic determines its unique risk in the marketcompetition From the perspective of overall corporate riskpipeline operation company like other enterprises shares thesame risks in terms of strategy law and human resourcesAccording to [26 28 29] the first level is gotten Then theevaluation criteria are established based on [11 26 28ndash70]which are shown in Table 1

31 Strategic Risk Strategic risk of the natural gas pipelinecompany includes the external macro environment theindustries the resources and capabilities in the enterprises[30ndash32]

311 Macro Environment National policies and regulationshave influences on themacro environment To encourage andsupport the exploration and utilization of natural gas a seriesof preferential policies are issued [33] If these preferentialpolicies change the company will be influenced significantlyPipeline companies sell natural gas to downstream industrialand commercial enterprises to make profits [34] If thedomestic economy goes down the pipeline enterprises willface the decrease of downstream users and the reduction ofgas consumption [35]

312 Industry and Competition Risk In most countries thenatural gas industry is monopolized [36] The transportationand sales of natural gas are controlled by the natural gaspipeline company The alternative pipeline transportationproduct such as LNG photovoltaic and wind energy willbreak the monopoly Meanwhile with the introducing ofnew competitors companies will have to reduce margins toparticipate in competitions

313 Internal Resources and Capacity Risk Strategic plan-ning implementation investment decision-making andoperational capability have influence on the internalresources and capacity risk [37] It is mainly reflected in theunreasonable strategic decision-making market positioningis not accurate and the development strategy is not clearThe mismatch between the organizational structure andoperation mode and the development strategy will lead tothe results that the implementation of the strategy is blockedand the strategic awareness of all staff in the organization isweak and the planning and execution of the unit cannot becarried out in good accordance with the corporate strategy

32 Market Risk Market risk refers to the interactionbetween participants in the market competition whichcauses the change of supply and demand in the market andthe uncertainty of this change forms the market risk [38]

The market risk factors of the enterprise can be summedup in four aspects downstream user risk unbalanced market

supply and demand risk market price risk and competitionrisk [39 40]

321 Downstream User Risk Downstream natural gas pipe-line users include industrial users city gas LNG and CNG[41] Downstream user risk is mainly reflected in the gasconsumption instability and downstream users stickinessinstability The instability of the gas season will bring unbal-anced supply andmarketing risks to the upstream explorationand development and midstream pipeline transportationenterprises In the precondition that the gas has no muchmore price advantage compared with the oil coal and othertraditional energy fuel the cost of equipment replacementand branch line construction will reduce the customer stick-iness

322 The Imbalance between Supply and Demand RisksThe relationship between supply and demand in the marketdetermines the position of buyers and sellers in the marketFor example in this country with undeveloped industry theaverage daily gas consumption is much less than the optimaldesigned annual gas transmission volume As a result thenew developed natural gas field is overproduction forming abuyerrsquos market and the profit margins of upstream gas fieldsandmidstream processing plants and pipeline enterprises aredeclining

323 Price Risk The major income resource of the naturalgas pipeline companies is pipeline transportation fee Thepricing mechanism of natural gas prices mainly refer to theprice of natural gas and natural gas substitute fuels suchas oil prices in the international market and then calculatethe domestic various types of rates tax rates and upstreammining costs and profits to make a comprehensive pricingWith the increase of postproduction costs and operatingcosts natural gas prices will be raised accordingly Gas powerplants ceramics factories and cement plants are sensitive toprice changes Natural gas prices rise will inevitably lead tothe loss of some customers

324 Competition Risk The market competition risks ofnatural gas pipeline enterprises are mainly reflected in thecompetition risks of the main alternative energy utilizationand competitor risks The technological development andprice changes of alternative energy sources will directlycompete with the consumption of natural gas With thedevelopment of technologies such as LNG and LPG moreand more countries export LNG and LPG and LNG andLPG in the international market will also compete withtheir own countriesrsquo natural gas enterprises Meanwhile theother natural gas pipeline will also compete with pipelinecompanies for customer resources

33 Financial Risk Corporate financial risk refers to the riskof financial loss caused by the lack of financial rules andregulations financial operations and fund management andother noncompliance The financial risk includes corporatesolvency capital operation ability corporate profitability andsustainable development capacity aspects [42 43]

4 Mathematical Problems in Engineering

331 Corporate Solvency Risk The liquidity ratio and thequick ratio reflect the ability of the enterprise to repay thecurrent debt in the short term and they are respectivelyequal to the circulating assets and the ratio of the quickassets to the cash liabilities in a financial period Theratio of firmrsquos equity reflects the strength and weakness ofthe stability of the basic financial structure from a singleperspective Interest guarantee rate is used to measure theprofitability of the enterprise in the current period to repayinterest The cash flow debt ratio of a company is used tomeasure the current ability of an enterprise to repay short-term debts Long-term asset suitability of enterprises canbe used to measure the strength of long-term corporatesolvency

332 Enterprise Operational Capacity Risk The analysis ofthe risk of an enterprisersquos operational capability can be startedby calculating the financial indicators related to the turnoverof the enterprisersquos capital [43ndash45] Enterprise accounts receiv-able [46] turnover rate can be used to measure the flowof corporate accounts receivable The enterprise inventoryturnover rate [47] can be used tomeasure the turnover rate ofthe enterprise inventory Liquidity [48] turnover can be usedto measure the profitability of liquid assets in the enterpriseThe total asset turnover [49] of an enterprise can be used tomeasure the rate at which an enterprise invests its assets intooutput during the business cycle Nonperforming assets ratio[50] refers to the ratio of nonperforming assets to the totalassets of an enterprise in a financial period which can be usedtomeasure the nonperforming assets of enterprisesThe assetloss [51] rate refers to the ratio of the loss on fixed assets to thebeginning of the total fixed assets in a financial period whichreflects the loss of fixed assets of the enterprise

333 Enterprise Profitability Risk The analysis of corporateprofitability risk can be measured from the following indica-tors [52] Operating profit margins measure howmuch profita business unit makes Return on total assets can measure thesize of the companyrsquos assets operating efficiency Capital rateof return can reflect the ability of its own capital to obtain netincomeThe cost-of-business profit marginmeasures the costof investing the profit per unit of business

334 Enterprise Development Capability Risk Analysis ofenterprise development capability risk can start with thefollowing indicators Sales growth rate refers to the ratioof sales revenue growth and total sales revenue in the lastfinancial cycle in a financial cycle It is an important indicatorto reflect whether the enterprise is in good condition and themarket possession ability is strong or weak [53]

34 Operational Risk Operational risks of natural gas pipe-line operation management are classified into human re-source risk material procurement management risk man-agement system risk and HSE risk [26 54 55]

341 Human Resource Risk Human resources risk is mainlyin the following areas [56ndash58] The unqualified person may

be recruited into the enterprise due to the asymmetricinformation in the labor market or the unclear job demandanalysis of the recruiters The loss of staff wastage occurswhen the employeersquos contribution to the enterprise has notreached the capital cost invested by the enterprise Employeesneglect their duties abuse their powers or violate the enter-prise management system to cause financial and reputationlosses to the enterprise Staff injuries cause the enterpriseincome loss and expenses Human resource managersrsquo lack-ing of ability and management ethics causes the managerialcorruption [59]

342 Material Procurement Risk Thematerial procurementis mainly reflected in three aspects procurement cost pro-curement quality and procurement time [60] When it isimpossible to purchase materials and spare parts for thedaily operation and maintenance of the pipeline at home theenterprises must invite tenders fromabroad for procurementThe procurement cost risk is incurred in international pro-curement due to price fluctuation exchange rate fluctuationand default of bidders Purchasing quality is influencedby suppliersrsquo noncompliance of supplier quality incompletequality supervision and unqualified quality inspection Theprocurement time also has influence on the risk since the pro-duction operation is blocked due to the poor procurementthe equipment operation risk increases and the emergencyrequirement cannot be satisfied [61 62]

343 Management System Risk The risk of managementsystem ismainly manifested in the fact that due to this naturalgas pipeline management company just taking over the oper-ation from the construction parties various managementsystems in daily operation and management have not beenestablished yet It will lead to risks such as unscrupulousoperation inefficiency and poor risk control

344 HSE Risk HSE (Health Safety and Environment)[63] risk refers to the risk caused by the HSE managementwhich is not in place and HSE management system is notestablished or not completed HSE budget is insufficientSafety hazards may not be rectified timely Many other factorsalso have influence on the HSE risk such as lacking of staffsafety education fatal accidents pipeline explosion leakageaccidents and employee occupational injuries [64 65]

35 Legal Risk Natural gas transmission pipeline has longdistance and wide coverage The relationship between enter-prises and local governments is complicated There are con-tract risks legal risks of safety and environmental protectionlabor law risks and operation compliance risks in operationof natural gas pipeline [63]

351 Contract Risk The contract risk is reflected in thesigning and fulfillment of the contract [66] The naturalgas pipeline company is in the middle position in the oiland gas industry chain and plays a role of transformationTherefore many contracts and market transactions existbetween pipeline companies and upstream gas fields anddownstream users Once the contract is formulated and

Mathematical Problems in Engineering 5

implemented the enterprise will face the risk of breach ofcontract [67]

352 Safety and Environmental Legal Risks Natural gas pipe-line transportation industry belongs to the high-risk industry[11 68] The massive natural gas leakage will cause somepollution to the environment [69 70] The high-pressurenatural gas pipeline passes through the villages and citiesalong the pipeline route Once the leakage explosion andfire accidents occur the consequences will be disastrousTherefore the pipeline safety management is under strictsupervision of local authorities

353 Labor Law Risks The operation of pipelines employsmany workers and has diversified employment patternsThere are protection mechanisms for employeesrsquo rightsEspecially with the improvement of the education level of thestaff the awareness of rights protection is very strong

354 Operation Compliance Risk Operation compliancerisks are mainly reflected in the business-related licenses orqualifications that have not been obtained for a businessThere is no synchronization with the latest laws regulationsor industry standards promulgated by the state Companymay be charged with illegal business operations and so on

4 Method to Deal with the LinguisticEvaluation Information in IntuitionisticFuzzy Linguistic Environment

Evaluators 119890119896 evaluate the alternative 119898119894 according to thecriterion 119888119895 to obtain the intuitionistic fuzzy decision matrix119877119896 = (120572119896119894119895)119899times119898 under the attribute of the alternative in which120572119896119894119895 = (120583119896119894119895 V119896119894119895) 0 le 120583119896119894119895 le 1 0 le V119896119894119895 le 1 0 le 120583119896119894119895+V119896119894119895 le1 120587119896119894119895 = 1 minus 120583119896119894119895 minus V119896119894119895 and 120583119896119894119895 V119896119894119895 120587119896119894119895 respectively expresses thesatisfaction dissatisfaction and hesitancy degree of evaluator119890119896 under the attributes 119888119895 of the alternative 119898119894

The higher the consistency of expertsrsquo opinion on eval-uation of criteria weight the greater the weight of expertsin weight evaluation [71] More experts agree on the criteriaweight and risk assessment the more understanding of thecriteria and the enterprise risk the greater the weight of theexperts in the risk assessment In the following based on thework [23ndash25 71 72] the linguistic evaluation information isdealt with by the following steps

Step 1 Assume that the rating of alternative mi with respectto criterion 119888119895 given by the evaluators 119890119896 can be expressedin IFS 119903(119896)119894119895 = (120583(119896)119894119895 V(119896)119894119895 120587(119896)119894119895 ) the rating of importance ofcriterion 119888119895 given by the evaluators119890119896 can be expressed inIFS 119908(119896)119895 = (120583(119896)119895 V(119896)119895 120587(119896)119895 ) Therefore the corresponding

Step 32The entropy weights of evaluators based on the evaluation

of the company can be calculated with (16)-(17)

119867119909 (1198901) = 013

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

2 Intuitionistic Fuzzy Sets

Due to the complexity and uncertainty of candidates somecriteria are more suitable for evaluation in linguistic formThe linguistic terms are mostly modeled with triangularfuzzy number [15 16] Afterwards intuitionistic fuzzy sets areproposed to model the linguistic terms [17] Compared withfuzzy sets which only consider the degree of membershipintuitionistic fuzzy sets is characterized by both a member-ship function and a nonmembership function and the sum ofboth values is allowed to be less than one [18] It has been usedsuch as in the area of search algorithm selection [19] RuralLogistics Center Location [20] information system projectselection [21] and green supply chain [22] In the followingintuitionistic fuzzy sets are reviewed briefly [17 18 23ndash25]

Definition 1 (see [17]) Let X be a given finite set then definean intuitionistic fuzzy set on X as A

in which 120583119860 119883 997888rarr [0 1] and V119860 119883 997888rarr[0 1] are respectively the membership function and thenonmembership function with the condition 0 le 120583119860(119909) +V119860(119909) le 1

In addition 120587119860(119909) = 1 minus 120583119860(119909) minus V119860(119909) represents theintuitionistic fuzzy index or hesitancy degree of whether 119909belongs to 119860 or not with the condition 0 le 120587119860(119909) le 1Definition 2 (see [18]) Arithmetic operations on intuitionis-tic fuzzy numbers

Let both 120572 = (120583119860 V119860) and 120573 = (120583119861 V119861) be intuitionisticfuzzy numbers and 120582 be real number The arithmetic opera-tions on intuitionistic fuzzy numbers are defined as follows

(5) 120572120573 = (min (120583119860 120583119861) max (V119860 V119861)) (6)

Definition 3 (see [25]) For intuitionistic fuzzy numbers thescore function of 120572 is defined as

119904 (120572) = 119896120583120572 minus 119896V120572 + (1 minus 2119896) 10038161003816100381610038161 minus (120583 + V120572)1003816100381610038161003816 (7)

where k reflects the decision attitude of the evaluator and 0 lt119896 lt 1

Definition 4 (see [24]) Entropy for intuitionistic fuzzy num-bers is as follows

3 Evaluation Criteria of the Risk of NaturalGas Pipeline Operation Management

Natural gas is a national strategic resource and its prod-uct characteristic determines its unique risk in the marketcompetition From the perspective of overall corporate riskpipeline operation company like other enterprises shares thesame risks in terms of strategy law and human resourcesAccording to [26 28 29] the first level is gotten Then theevaluation criteria are established based on [11 26 28ndash70]which are shown in Table 1

31 Strategic Risk Strategic risk of the natural gas pipelinecompany includes the external macro environment theindustries the resources and capabilities in the enterprises[30ndash32]

311 Macro Environment National policies and regulationshave influences on themacro environment To encourage andsupport the exploration and utilization of natural gas a seriesof preferential policies are issued [33] If these preferentialpolicies change the company will be influenced significantlyPipeline companies sell natural gas to downstream industrialand commercial enterprises to make profits [34] If thedomestic economy goes down the pipeline enterprises willface the decrease of downstream users and the reduction ofgas consumption [35]

312 Industry and Competition Risk In most countries thenatural gas industry is monopolized [36] The transportationand sales of natural gas are controlled by the natural gaspipeline company The alternative pipeline transportationproduct such as LNG photovoltaic and wind energy willbreak the monopoly Meanwhile with the introducing ofnew competitors companies will have to reduce margins toparticipate in competitions

313 Internal Resources and Capacity Risk Strategic plan-ning implementation investment decision-making andoperational capability have influence on the internalresources and capacity risk [37] It is mainly reflected in theunreasonable strategic decision-making market positioningis not accurate and the development strategy is not clearThe mismatch between the organizational structure andoperation mode and the development strategy will lead tothe results that the implementation of the strategy is blockedand the strategic awareness of all staff in the organization isweak and the planning and execution of the unit cannot becarried out in good accordance with the corporate strategy

32 Market Risk Market risk refers to the interactionbetween participants in the market competition whichcauses the change of supply and demand in the market andthe uncertainty of this change forms the market risk [38]

The market risk factors of the enterprise can be summedup in four aspects downstream user risk unbalanced market

supply and demand risk market price risk and competitionrisk [39 40]

321 Downstream User Risk Downstream natural gas pipe-line users include industrial users city gas LNG and CNG[41] Downstream user risk is mainly reflected in the gasconsumption instability and downstream users stickinessinstability The instability of the gas season will bring unbal-anced supply andmarketing risks to the upstream explorationand development and midstream pipeline transportationenterprises In the precondition that the gas has no muchmore price advantage compared with the oil coal and othertraditional energy fuel the cost of equipment replacementand branch line construction will reduce the customer stick-iness

322 The Imbalance between Supply and Demand RisksThe relationship between supply and demand in the marketdetermines the position of buyers and sellers in the marketFor example in this country with undeveloped industry theaverage daily gas consumption is much less than the optimaldesigned annual gas transmission volume As a result thenew developed natural gas field is overproduction forming abuyerrsquos market and the profit margins of upstream gas fieldsandmidstream processing plants and pipeline enterprises aredeclining

323 Price Risk The major income resource of the naturalgas pipeline companies is pipeline transportation fee Thepricing mechanism of natural gas prices mainly refer to theprice of natural gas and natural gas substitute fuels suchas oil prices in the international market and then calculatethe domestic various types of rates tax rates and upstreammining costs and profits to make a comprehensive pricingWith the increase of postproduction costs and operatingcosts natural gas prices will be raised accordingly Gas powerplants ceramics factories and cement plants are sensitive toprice changes Natural gas prices rise will inevitably lead tothe loss of some customers

324 Competition Risk The market competition risks ofnatural gas pipeline enterprises are mainly reflected in thecompetition risks of the main alternative energy utilizationand competitor risks The technological development andprice changes of alternative energy sources will directlycompete with the consumption of natural gas With thedevelopment of technologies such as LNG and LPG moreand more countries export LNG and LPG and LNG andLPG in the international market will also compete withtheir own countriesrsquo natural gas enterprises Meanwhile theother natural gas pipeline will also compete with pipelinecompanies for customer resources

33 Financial Risk Corporate financial risk refers to the riskof financial loss caused by the lack of financial rules andregulations financial operations and fund management andother noncompliance The financial risk includes corporatesolvency capital operation ability corporate profitability andsustainable development capacity aspects [42 43]

4 Mathematical Problems in Engineering

331 Corporate Solvency Risk The liquidity ratio and thequick ratio reflect the ability of the enterprise to repay thecurrent debt in the short term and they are respectivelyequal to the circulating assets and the ratio of the quickassets to the cash liabilities in a financial period Theratio of firmrsquos equity reflects the strength and weakness ofthe stability of the basic financial structure from a singleperspective Interest guarantee rate is used to measure theprofitability of the enterprise in the current period to repayinterest The cash flow debt ratio of a company is used tomeasure the current ability of an enterprise to repay short-term debts Long-term asset suitability of enterprises canbe used to measure the strength of long-term corporatesolvency

332 Enterprise Operational Capacity Risk The analysis ofthe risk of an enterprisersquos operational capability can be startedby calculating the financial indicators related to the turnoverof the enterprisersquos capital [43ndash45] Enterprise accounts receiv-able [46] turnover rate can be used to measure the flowof corporate accounts receivable The enterprise inventoryturnover rate [47] can be used tomeasure the turnover rate ofthe enterprise inventory Liquidity [48] turnover can be usedto measure the profitability of liquid assets in the enterpriseThe total asset turnover [49] of an enterprise can be used tomeasure the rate at which an enterprise invests its assets intooutput during the business cycle Nonperforming assets ratio[50] refers to the ratio of nonperforming assets to the totalassets of an enterprise in a financial period which can be usedtomeasure the nonperforming assets of enterprisesThe assetloss [51] rate refers to the ratio of the loss on fixed assets to thebeginning of the total fixed assets in a financial period whichreflects the loss of fixed assets of the enterprise

333 Enterprise Profitability Risk The analysis of corporateprofitability risk can be measured from the following indica-tors [52] Operating profit margins measure howmuch profita business unit makes Return on total assets can measure thesize of the companyrsquos assets operating efficiency Capital rateof return can reflect the ability of its own capital to obtain netincomeThe cost-of-business profit marginmeasures the costof investing the profit per unit of business

334 Enterprise Development Capability Risk Analysis ofenterprise development capability risk can start with thefollowing indicators Sales growth rate refers to the ratioof sales revenue growth and total sales revenue in the lastfinancial cycle in a financial cycle It is an important indicatorto reflect whether the enterprise is in good condition and themarket possession ability is strong or weak [53]

34 Operational Risk Operational risks of natural gas pipe-line operation management are classified into human re-source risk material procurement management risk man-agement system risk and HSE risk [26 54 55]

341 Human Resource Risk Human resources risk is mainlyin the following areas [56ndash58] The unqualified person may

be recruited into the enterprise due to the asymmetricinformation in the labor market or the unclear job demandanalysis of the recruiters The loss of staff wastage occurswhen the employeersquos contribution to the enterprise has notreached the capital cost invested by the enterprise Employeesneglect their duties abuse their powers or violate the enter-prise management system to cause financial and reputationlosses to the enterprise Staff injuries cause the enterpriseincome loss and expenses Human resource managersrsquo lack-ing of ability and management ethics causes the managerialcorruption [59]

342 Material Procurement Risk Thematerial procurementis mainly reflected in three aspects procurement cost pro-curement quality and procurement time [60] When it isimpossible to purchase materials and spare parts for thedaily operation and maintenance of the pipeline at home theenterprises must invite tenders fromabroad for procurementThe procurement cost risk is incurred in international pro-curement due to price fluctuation exchange rate fluctuationand default of bidders Purchasing quality is influencedby suppliersrsquo noncompliance of supplier quality incompletequality supervision and unqualified quality inspection Theprocurement time also has influence on the risk since the pro-duction operation is blocked due to the poor procurementthe equipment operation risk increases and the emergencyrequirement cannot be satisfied [61 62]

343 Management System Risk The risk of managementsystem ismainly manifested in the fact that due to this naturalgas pipeline management company just taking over the oper-ation from the construction parties various managementsystems in daily operation and management have not beenestablished yet It will lead to risks such as unscrupulousoperation inefficiency and poor risk control

344 HSE Risk HSE (Health Safety and Environment)[63] risk refers to the risk caused by the HSE managementwhich is not in place and HSE management system is notestablished or not completed HSE budget is insufficientSafety hazards may not be rectified timely Many other factorsalso have influence on the HSE risk such as lacking of staffsafety education fatal accidents pipeline explosion leakageaccidents and employee occupational injuries [64 65]

35 Legal Risk Natural gas transmission pipeline has longdistance and wide coverage The relationship between enter-prises and local governments is complicated There are con-tract risks legal risks of safety and environmental protectionlabor law risks and operation compliance risks in operationof natural gas pipeline [63]

351 Contract Risk The contract risk is reflected in thesigning and fulfillment of the contract [66] The naturalgas pipeline company is in the middle position in the oiland gas industry chain and plays a role of transformationTherefore many contracts and market transactions existbetween pipeline companies and upstream gas fields anddownstream users Once the contract is formulated and

Mathematical Problems in Engineering 5

implemented the enterprise will face the risk of breach ofcontract [67]

352 Safety and Environmental Legal Risks Natural gas pipe-line transportation industry belongs to the high-risk industry[11 68] The massive natural gas leakage will cause somepollution to the environment [69 70] The high-pressurenatural gas pipeline passes through the villages and citiesalong the pipeline route Once the leakage explosion andfire accidents occur the consequences will be disastrousTherefore the pipeline safety management is under strictsupervision of local authorities

353 Labor Law Risks The operation of pipelines employsmany workers and has diversified employment patternsThere are protection mechanisms for employeesrsquo rightsEspecially with the improvement of the education level of thestaff the awareness of rights protection is very strong

354 Operation Compliance Risk Operation compliancerisks are mainly reflected in the business-related licenses orqualifications that have not been obtained for a businessThere is no synchronization with the latest laws regulationsor industry standards promulgated by the state Companymay be charged with illegal business operations and so on

4 Method to Deal with the LinguisticEvaluation Information in IntuitionisticFuzzy Linguistic Environment

(27)

Step 8 In the condition that the weighted rating of thealternative with the parent criteria needs to be comparedbased on (7) the score function can be used as

119904 (120585119894119897) = 119896120588119894119897 minus 119896120590119894119897 + (1 minus 2119896) 10038161003816100381610038161 minus (120588119894119897 + 120590119894119897)1003816100381610038161003816 (28)

51 Deriving the Evaluation Results

Step 1 Construct the individual intuitionistic fuzzy decisionmatrix

Using Table 2 the initial ratings are converted into theintuitionistic fuzzy forms in Tables 3 and 4

Step 2 Construct the initial aggregated intuitionistic fuzzydecision matrix separately

matrix can be derived as is in the fourth column of Table 5Step 22Weights of the experts are equal with (13) the initial

aggregated intuitionistic fuzzy decision matrix of risk levelof the company can be derived as in the second column ofTable 5

Step 3 Obtain the entropy weightStep 31The entropy weights of evaluators based on the evaluation

of the criteria can be calculated with (14)-(15)

119867119888 (1198901) = 019119867119888 (1198902) = 019119867119888 (1198903) = 011119867119888 (1198904) = 012119867119888 (1198905) = 012119867119888 (1198906) = 013119867119888 (1198907) = 012

(29)

Step 32The entropy weights of evaluators based on the evaluation

of the company can be calculated with (16)-(17)

119867119909 (1198901) = 013

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

(30)

Step 4 Calculate the cross entropy weightStep 41With (18)-(19) the cross entropy weight of evaluators

based on evaluation of the criteria can be derived119862119888 (1198901)=014119862119888 (1198902) = 010119862119888 (1198903) = 019119862119888 (1198904) = 012119862119888 (1198905) = 016119862119888 (1198906) = 013119862119888 (1198907) = 016

(31)

Step 42With (20)-(21) the cross entropy weight of evaluators

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

312 Industry and Competition Risk In most countries thenatural gas industry is monopolized [36] The transportationand sales of natural gas are controlled by the natural gaspipeline company The alternative pipeline transportationproduct such as LNG photovoltaic and wind energy willbreak the monopoly Meanwhile with the introducing ofnew competitors companies will have to reduce margins toparticipate in competitions

313 Internal Resources and Capacity Risk Strategic plan-ning implementation investment decision-making andoperational capability have influence on the internalresources and capacity risk [37] It is mainly reflected in theunreasonable strategic decision-making market positioningis not accurate and the development strategy is not clearThe mismatch between the organizational structure andoperation mode and the development strategy will lead tothe results that the implementation of the strategy is blockedand the strategic awareness of all staff in the organization isweak and the planning and execution of the unit cannot becarried out in good accordance with the corporate strategy

32 Market Risk Market risk refers to the interactionbetween participants in the market competition whichcauses the change of supply and demand in the market andthe uncertainty of this change forms the market risk [38]

The market risk factors of the enterprise can be summedup in four aspects downstream user risk unbalanced market

supply and demand risk market price risk and competitionrisk [39 40]

321 Downstream User Risk Downstream natural gas pipe-line users include industrial users city gas LNG and CNG[41] Downstream user risk is mainly reflected in the gasconsumption instability and downstream users stickinessinstability The instability of the gas season will bring unbal-anced supply andmarketing risks to the upstream explorationand development and midstream pipeline transportationenterprises In the precondition that the gas has no muchmore price advantage compared with the oil coal and othertraditional energy fuel the cost of equipment replacementand branch line construction will reduce the customer stick-iness

322 The Imbalance between Supply and Demand RisksThe relationship between supply and demand in the marketdetermines the position of buyers and sellers in the marketFor example in this country with undeveloped industry theaverage daily gas consumption is much less than the optimaldesigned annual gas transmission volume As a result thenew developed natural gas field is overproduction forming abuyerrsquos market and the profit margins of upstream gas fieldsandmidstream processing plants and pipeline enterprises aredeclining

323 Price Risk The major income resource of the naturalgas pipeline companies is pipeline transportation fee Thepricing mechanism of natural gas prices mainly refer to theprice of natural gas and natural gas substitute fuels suchas oil prices in the international market and then calculatethe domestic various types of rates tax rates and upstreammining costs and profits to make a comprehensive pricingWith the increase of postproduction costs and operatingcosts natural gas prices will be raised accordingly Gas powerplants ceramics factories and cement plants are sensitive toprice changes Natural gas prices rise will inevitably lead tothe loss of some customers

324 Competition Risk The market competition risks ofnatural gas pipeline enterprises are mainly reflected in thecompetition risks of the main alternative energy utilizationand competitor risks The technological development andprice changes of alternative energy sources will directlycompete with the consumption of natural gas With thedevelopment of technologies such as LNG and LPG moreand more countries export LNG and LPG and LNG andLPG in the international market will also compete withtheir own countriesrsquo natural gas enterprises Meanwhile theother natural gas pipeline will also compete with pipelinecompanies for customer resources

33 Financial Risk Corporate financial risk refers to the riskof financial loss caused by the lack of financial rules andregulations financial operations and fund management andother noncompliance The financial risk includes corporatesolvency capital operation ability corporate profitability andsustainable development capacity aspects [42 43]

4 Mathematical Problems in Engineering

331 Corporate Solvency Risk The liquidity ratio and thequick ratio reflect the ability of the enterprise to repay thecurrent debt in the short term and they are respectivelyequal to the circulating assets and the ratio of the quickassets to the cash liabilities in a financial period Theratio of firmrsquos equity reflects the strength and weakness ofthe stability of the basic financial structure from a singleperspective Interest guarantee rate is used to measure theprofitability of the enterprise in the current period to repayinterest The cash flow debt ratio of a company is used tomeasure the current ability of an enterprise to repay short-term debts Long-term asset suitability of enterprises canbe used to measure the strength of long-term corporatesolvency

332 Enterprise Operational Capacity Risk The analysis ofthe risk of an enterprisersquos operational capability can be startedby calculating the financial indicators related to the turnoverof the enterprisersquos capital [43ndash45] Enterprise accounts receiv-able [46] turnover rate can be used to measure the flowof corporate accounts receivable The enterprise inventoryturnover rate [47] can be used tomeasure the turnover rate ofthe enterprise inventory Liquidity [48] turnover can be usedto measure the profitability of liquid assets in the enterpriseThe total asset turnover [49] of an enterprise can be used tomeasure the rate at which an enterprise invests its assets intooutput during the business cycle Nonperforming assets ratio[50] refers to the ratio of nonperforming assets to the totalassets of an enterprise in a financial period which can be usedtomeasure the nonperforming assets of enterprisesThe assetloss [51] rate refers to the ratio of the loss on fixed assets to thebeginning of the total fixed assets in a financial period whichreflects the loss of fixed assets of the enterprise

333 Enterprise Profitability Risk The analysis of corporateprofitability risk can be measured from the following indica-tors [52] Operating profit margins measure howmuch profita business unit makes Return on total assets can measure thesize of the companyrsquos assets operating efficiency Capital rateof return can reflect the ability of its own capital to obtain netincomeThe cost-of-business profit marginmeasures the costof investing the profit per unit of business

334 Enterprise Development Capability Risk Analysis ofenterprise development capability risk can start with thefollowing indicators Sales growth rate refers to the ratioof sales revenue growth and total sales revenue in the lastfinancial cycle in a financial cycle It is an important indicatorto reflect whether the enterprise is in good condition and themarket possession ability is strong or weak [53]

34 Operational Risk Operational risks of natural gas pipe-line operation management are classified into human re-source risk material procurement management risk man-agement system risk and HSE risk [26 54 55]

341 Human Resource Risk Human resources risk is mainlyin the following areas [56ndash58] The unqualified person may

be recruited into the enterprise due to the asymmetricinformation in the labor market or the unclear job demandanalysis of the recruiters The loss of staff wastage occurswhen the employeersquos contribution to the enterprise has notreached the capital cost invested by the enterprise Employeesneglect their duties abuse their powers or violate the enter-prise management system to cause financial and reputationlosses to the enterprise Staff injuries cause the enterpriseincome loss and expenses Human resource managersrsquo lack-ing of ability and management ethics causes the managerialcorruption [59]

342 Material Procurement Risk Thematerial procurementis mainly reflected in three aspects procurement cost pro-curement quality and procurement time [60] When it isimpossible to purchase materials and spare parts for thedaily operation and maintenance of the pipeline at home theenterprises must invite tenders fromabroad for procurementThe procurement cost risk is incurred in international pro-curement due to price fluctuation exchange rate fluctuationand default of bidders Purchasing quality is influencedby suppliersrsquo noncompliance of supplier quality incompletequality supervision and unqualified quality inspection Theprocurement time also has influence on the risk since the pro-duction operation is blocked due to the poor procurementthe equipment operation risk increases and the emergencyrequirement cannot be satisfied [61 62]

343 Management System Risk The risk of managementsystem ismainly manifested in the fact that due to this naturalgas pipeline management company just taking over the oper-ation from the construction parties various managementsystems in daily operation and management have not beenestablished yet It will lead to risks such as unscrupulousoperation inefficiency and poor risk control

344 HSE Risk HSE (Health Safety and Environment)[63] risk refers to the risk caused by the HSE managementwhich is not in place and HSE management system is notestablished or not completed HSE budget is insufficientSafety hazards may not be rectified timely Many other factorsalso have influence on the HSE risk such as lacking of staffsafety education fatal accidents pipeline explosion leakageaccidents and employee occupational injuries [64 65]

35 Legal Risk Natural gas transmission pipeline has longdistance and wide coverage The relationship between enter-prises and local governments is complicated There are con-tract risks legal risks of safety and environmental protectionlabor law risks and operation compliance risks in operationof natural gas pipeline [63]

351 Contract Risk The contract risk is reflected in thesigning and fulfillment of the contract [66] The naturalgas pipeline company is in the middle position in the oiland gas industry chain and plays a role of transformationTherefore many contracts and market transactions existbetween pipeline companies and upstream gas fields anddownstream users Once the contract is formulated and

Mathematical Problems in Engineering 5

implemented the enterprise will face the risk of breach ofcontract [67]

352 Safety and Environmental Legal Risks Natural gas pipe-line transportation industry belongs to the high-risk industry[11 68] The massive natural gas leakage will cause somepollution to the environment [69 70] The high-pressurenatural gas pipeline passes through the villages and citiesalong the pipeline route Once the leakage explosion andfire accidents occur the consequences will be disastrousTherefore the pipeline safety management is under strictsupervision of local authorities

353 Labor Law Risks The operation of pipelines employsmany workers and has diversified employment patternsThere are protection mechanisms for employeesrsquo rightsEspecially with the improvement of the education level of thestaff the awareness of rights protection is very strong

354 Operation Compliance Risk Operation compliancerisks are mainly reflected in the business-related licenses orqualifications that have not been obtained for a businessThere is no synchronization with the latest laws regulationsor industry standards promulgated by the state Companymay be charged with illegal business operations and so on

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

(30)

Step 4 Calculate the cross entropy weightStep 41With (18)-(19) the cross entropy weight of evaluators

based on evaluation of the criteria can be derived119862119888 (1198901)=014119862119888 (1198902) = 010119862119888 (1198903) = 019119862119888 (1198904) = 012119862119888 (1198905) = 016119862119888 (1198906) = 013119862119888 (1198907) = 016

(31)

Step 42With (20)-(21) the cross entropy weight of evaluators

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

4 Mathematical Problems in Engineering

331 Corporate Solvency Risk The liquidity ratio and thequick ratio reflect the ability of the enterprise to repay thecurrent debt in the short term and they are respectivelyequal to the circulating assets and the ratio of the quickassets to the cash liabilities in a financial period Theratio of firmrsquos equity reflects the strength and weakness ofthe stability of the basic financial structure from a singleperspective Interest guarantee rate is used to measure theprofitability of the enterprise in the current period to repayinterest The cash flow debt ratio of a company is used tomeasure the current ability of an enterprise to repay short-term debts Long-term asset suitability of enterprises canbe used to measure the strength of long-term corporatesolvency

332 Enterprise Operational Capacity Risk The analysis ofthe risk of an enterprisersquos operational capability can be startedby calculating the financial indicators related to the turnoverof the enterprisersquos capital [43ndash45] Enterprise accounts receiv-able [46] turnover rate can be used to measure the flowof corporate accounts receivable The enterprise inventoryturnover rate [47] can be used tomeasure the turnover rate ofthe enterprise inventory Liquidity [48] turnover can be usedto measure the profitability of liquid assets in the enterpriseThe total asset turnover [49] of an enterprise can be used tomeasure the rate at which an enterprise invests its assets intooutput during the business cycle Nonperforming assets ratio[50] refers to the ratio of nonperforming assets to the totalassets of an enterprise in a financial period which can be usedtomeasure the nonperforming assets of enterprisesThe assetloss [51] rate refers to the ratio of the loss on fixed assets to thebeginning of the total fixed assets in a financial period whichreflects the loss of fixed assets of the enterprise

333 Enterprise Profitability Risk The analysis of corporateprofitability risk can be measured from the following indica-tors [52] Operating profit margins measure howmuch profita business unit makes Return on total assets can measure thesize of the companyrsquos assets operating efficiency Capital rateof return can reflect the ability of its own capital to obtain netincomeThe cost-of-business profit marginmeasures the costof investing the profit per unit of business

334 Enterprise Development Capability Risk Analysis ofenterprise development capability risk can start with thefollowing indicators Sales growth rate refers to the ratioof sales revenue growth and total sales revenue in the lastfinancial cycle in a financial cycle It is an important indicatorto reflect whether the enterprise is in good condition and themarket possession ability is strong or weak [53]

34 Operational Risk Operational risks of natural gas pipe-line operation management are classified into human re-source risk material procurement management risk man-agement system risk and HSE risk [26 54 55]

341 Human Resource Risk Human resources risk is mainlyin the following areas [56ndash58] The unqualified person may

be recruited into the enterprise due to the asymmetricinformation in the labor market or the unclear job demandanalysis of the recruiters The loss of staff wastage occurswhen the employeersquos contribution to the enterprise has notreached the capital cost invested by the enterprise Employeesneglect their duties abuse their powers or violate the enter-prise management system to cause financial and reputationlosses to the enterprise Staff injuries cause the enterpriseincome loss and expenses Human resource managersrsquo lack-ing of ability and management ethics causes the managerialcorruption [59]

342 Material Procurement Risk Thematerial procurementis mainly reflected in three aspects procurement cost pro-curement quality and procurement time [60] When it isimpossible to purchase materials and spare parts for thedaily operation and maintenance of the pipeline at home theenterprises must invite tenders fromabroad for procurementThe procurement cost risk is incurred in international pro-curement due to price fluctuation exchange rate fluctuationand default of bidders Purchasing quality is influencedby suppliersrsquo noncompliance of supplier quality incompletequality supervision and unqualified quality inspection Theprocurement time also has influence on the risk since the pro-duction operation is blocked due to the poor procurementthe equipment operation risk increases and the emergencyrequirement cannot be satisfied [61 62]

343 Management System Risk The risk of managementsystem ismainly manifested in the fact that due to this naturalgas pipeline management company just taking over the oper-ation from the construction parties various managementsystems in daily operation and management have not beenestablished yet It will lead to risks such as unscrupulousoperation inefficiency and poor risk control

344 HSE Risk HSE (Health Safety and Environment)[63] risk refers to the risk caused by the HSE managementwhich is not in place and HSE management system is notestablished or not completed HSE budget is insufficientSafety hazards may not be rectified timely Many other factorsalso have influence on the HSE risk such as lacking of staffsafety education fatal accidents pipeline explosion leakageaccidents and employee occupational injuries [64 65]

35 Legal Risk Natural gas transmission pipeline has longdistance and wide coverage The relationship between enter-prises and local governments is complicated There are con-tract risks legal risks of safety and environmental protectionlabor law risks and operation compliance risks in operationof natural gas pipeline [63]

351 Contract Risk The contract risk is reflected in thesigning and fulfillment of the contract [66] The naturalgas pipeline company is in the middle position in the oiland gas industry chain and plays a role of transformationTherefore many contracts and market transactions existbetween pipeline companies and upstream gas fields anddownstream users Once the contract is formulated and

Mathematical Problems in Engineering 5

implemented the enterprise will face the risk of breach ofcontract [67]

352 Safety and Environmental Legal Risks Natural gas pipe-line transportation industry belongs to the high-risk industry[11 68] The massive natural gas leakage will cause somepollution to the environment [69 70] The high-pressurenatural gas pipeline passes through the villages and citiesalong the pipeline route Once the leakage explosion andfire accidents occur the consequences will be disastrousTherefore the pipeline safety management is under strictsupervision of local authorities

353 Labor Law Risks The operation of pipelines employsmany workers and has diversified employment patternsThere are protection mechanisms for employeesrsquo rightsEspecially with the improvement of the education level of thestaff the awareness of rights protection is very strong

354 Operation Compliance Risk Operation compliancerisks are mainly reflected in the business-related licenses orqualifications that have not been obtained for a businessThere is no synchronization with the latest laws regulationsor industry standards promulgated by the state Companymay be charged with illegal business operations and so on

4 Method to Deal with the LinguisticEvaluation Information in IntuitionisticFuzzy Linguistic Environment

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights of evaluator 119890119896

Step 51According to the cross entropy weights and entropy

weights of evaluator 119890119896 on the evaluation of importance ofcriteria we can get the corresponding final weight 120578119896119888 by

120578119896119888 = 120572119862119888 (119890119896) + (1 minus 120572)119867119888 (119890119896) (22)

where 0 le 120572 le 1Step 52According to the cross entropy weights and entropy

weights of evaluators on the evaluation of alternative 119898119894 wecan get the corresponding final weight 120578119870119894 by

120578119896119894 = 120572119862119898119894 (119890119896) + (1 minus 120572)119867119898119894 (119890119896) (23)

where 0 le 120572 le 1Step 53Based on 120578119896119888 and 120578119896119894 calculate the corresponding final

weight 120578119896 which comprehensively considers the consistencyof indicator evaluation and the indicator scores of evaluatorsby

120578119896 = 120579120578119896119888 + (1 minus 120579) 120578119896119894 (24)

where 0 le 120579 le 1Step 6 Calculate the integrated evaluation result matrix

Step 61Integrating the weight based on the rating of criteria

of evaluators based on (4) the integrated evaluation resultmatrix 119861119888 = (1205731 1205732 120573119899) of criteria can be obtained by

120573119895 = 119904sum119896=1

119908(119896)119895 120578119896119888 = (120588119895 120590119895) (25)

120572(119896)119894119895 120578119896 = (120588119894119895 120590119894119895) (26)

Step 7 Determine the final evaluation results Based on(2)ndash(6) the weighted evaluation value of the alternative 119898119894with respect to the parent criteria 119862119897 can be derived by

120585119894119897 = sum119888119895isin119862119897 120573119894119895 otimes 120573119895sum119888119895isin119862119897 120573119895 = sum119888119895isin119862119897 (120588119894119895 120590119894119895) otimes (120588119895 120590119895)sum119888119895isin119862119897 (120588119895 120590119895)= (120588119894119897 120590119894119897)

(27)

Step 8 In the condition that the weighted rating of thealternative with the parent criteria needs to be comparedbased on (7) the score function can be used as

119904 (120585119894119897) = 119896120588119894119897 minus 119896120590119894119897 + (1 minus 2119896) 10038161003816100381610038161 minus (120588119894119897 + 120590119894119897)1003816100381610038161003816 (28)

In order to control the risks of X Gas Pipeline Company theproposed approach is used to evaluate the risks Seven peopleare invited to evaluate the risk of company and the weight ofcriteria using the linguistic terms in Table 2

51 Deriving the Evaluation Results

Step 1 Construct the individual intuitionistic fuzzy decisionmatrix

Using Table 2 the initial ratings are converted into theintuitionistic fuzzy forms in Tables 3 and 4

Step 2 Construct the initial aggregated intuitionistic fuzzydecision matrix separately

Step 21Weights of the experts are equal then with (11)-(12) the

matrix can be derived as is in the fourth column of Table 5Step 22Weights of the experts are equal with (13) the initial

aggregated intuitionistic fuzzy decision matrix of risk levelof the company can be derived as in the second column ofTable 5

Step 3 Obtain the entropy weightStep 31The entropy weights of evaluators based on the evaluation

of the criteria can be calculated with (14)-(15)

119867119888 (1198901) = 019119867119888 (1198902) = 019119867119888 (1198903) = 011119867119888 (1198904) = 012119867119888 (1198905) = 012119867119888 (1198906) = 013119867119888 (1198907) = 012

(29)

Step 32The entropy weights of evaluators based on the evaluation

of the company can be calculated with (16)-(17)

119867119909 (1198901) = 013

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

(30)

Step 4 Calculate the cross entropy weightStep 41With (18)-(19) the cross entropy weight of evaluators

based on evaluation of the criteria can be derived119862119888 (1198901)=014119862119888 (1198902) = 010119862119888 (1198903) = 019119862119888 (1198904) = 012119862119888 (1198905) = 016119862119888 (1198906) = 013119862119888 (1198907) = 016

(31)

Step 42With (20)-(21) the cross entropy weight of evaluators

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

352 Safety and Environmental Legal Risks Natural gas pipe-line transportation industry belongs to the high-risk industry[11 68] The massive natural gas leakage will cause somepollution to the environment [69 70] The high-pressurenatural gas pipeline passes through the villages and citiesalong the pipeline route Once the leakage explosion andfire accidents occur the consequences will be disastrousTherefore the pipeline safety management is under strictsupervision of local authorities

353 Labor Law Risks The operation of pipelines employsmany workers and has diversified employment patternsThere are protection mechanisms for employeesrsquo rightsEspecially with the improvement of the education level of thestaff the awareness of rights protection is very strong

354 Operation Compliance Risk Operation compliancerisks are mainly reflected in the business-related licenses orqualifications that have not been obtained for a businessThere is no synchronization with the latest laws regulationsor industry standards promulgated by the state Companymay be charged with illegal business operations and so on

4 Method to Deal with the LinguisticEvaluation Information in IntuitionisticFuzzy Linguistic Environment

Evaluators 119890119896 evaluate the alternative 119898119894 according to thecriterion 119888119895 to obtain the intuitionistic fuzzy decision matrix119877119896 = (120572119896119894119895)119899times119898 under the attribute of the alternative in which120572119896119894119895 = (120583119896119894119895 V119896119894119895) 0 le 120583119896119894119895 le 1 0 le V119896119894119895 le 1 0 le 120583119896119894119895+V119896119894119895 le1 120587119896119894119895 = 1 minus 120583119896119894119895 minus V119896119894119895 and 120583119896119894119895 V119896119894119895 120587119896119894119895 respectively expresses thesatisfaction dissatisfaction and hesitancy degree of evaluator119890119896 under the attributes 119888119895 of the alternative 119898119894

The higher the consistency of expertsrsquo opinion on eval-uation of criteria weight the greater the weight of expertsin weight evaluation [71] More experts agree on the criteriaweight and risk assessment the more understanding of thecriteria and the enterprise risk the greater the weight of theexperts in the risk assessment In the following based on thework [23ndash25 71 72] the linguistic evaluation information isdealt with by the following steps

Step 1 Assume that the rating of alternative mi with respectto criterion 119888119895 given by the evaluators 119890119896 can be expressedin IFS 119903(119896)119894119895 = (120583(119896)119894119895 V(119896)119894119895 120587(119896)119894119895 ) the rating of importance ofcriterion 119888119895 given by the evaluators119890119896 can be expressed inIFS 119908(119896)119895 = (120583(119896)119895 V(119896)119895 120587(119896)119895 ) Therefore the corresponding

intuitionistic fuzzy decision matrices 119877(119896) and 119882(119896) can beexpressed in matrix form concisely as follows

119877(119896) = (119903(119896)119894119895 )119899times119898 =[[[[[[[[

matrix can be derived as is in the fourth column of Table 5Step 22Weights of the experts are equal with (13) the initial

aggregated intuitionistic fuzzy decision matrix of risk levelof the company can be derived as in the second column ofTable 5

Step 3 Obtain the entropy weightStep 31The entropy weights of evaluators based on the evaluation

of the criteria can be calculated with (14)-(15)

119867119888 (1198901) = 019119867119888 (1198902) = 019119867119888 (1198903) = 011119867119888 (1198904) = 012119867119888 (1198905) = 012119867119888 (1198906) = 013119867119888 (1198907) = 012

(29)

Step 32The entropy weights of evaluators based on the evaluation

of the company can be calculated with (16)-(17)

119867119909 (1198901) = 013

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

(30)

Step 4 Calculate the cross entropy weightStep 41With (18)-(19) the cross entropy weight of evaluators

based on evaluation of the criteria can be derived119862119888 (1198901)=014119862119888 (1198902) = 010119862119888 (1198903) = 019119862119888 (1198904) = 012119862119888 (1198905) = 016119862119888 (1198906) = 013119862119888 (1198907) = 016

(31)

Step 42With (20)-(21) the cross entropy weight of evaluators

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights of evaluator 119890119896

Step 51According to the cross entropy weights and entropy

weights of evaluator 119890119896 on the evaluation of importance ofcriteria we can get the corresponding final weight 120578119896119888 by

120578119896119888 = 120572119862119888 (119890119896) + (1 minus 120572)119867119888 (119890119896) (22)

where 0 le 120572 le 1Step 52According to the cross entropy weights and entropy

weights of evaluators on the evaluation of alternative 119898119894 wecan get the corresponding final weight 120578119870119894 by

where 0 le 120572 le 1Step 53Based on 120578119896119888 and 120578119896119894 calculate the corresponding final

weight 120578119896 which comprehensively considers the consistencyof indicator evaluation and the indicator scores of evaluatorsby

120578119896 = 120579120578119896119888 + (1 minus 120579) 120578119896119894 (24)

where 0 le 120579 le 1Step 6 Calculate the integrated evaluation result matrix

Step 61Integrating the weight based on the rating of criteria

of evaluators based on (4) the integrated evaluation resultmatrix 119861119888 = (1205731 1205732 120573119899) of criteria can be obtained by

120573119895 = 119904sum119896=1

119908(119896)119895 120578119896119888 = (120588119895 120590119895) (25)

Step 62Integrating the weight based on both the rating of

alternatives and the rating of criteria of evaluators based on(4) the integrated evaluation result matrix 119861119898119894 = (120573119894119895)119899times119898 ofalternative 119898119894 is derived by

120572(119896)119894119895 120578119896 = (120588119894119895 120590119894119895) (26)

Step 7 Determine the final evaluation results Based on(2)ndash(6) the weighted evaluation value of the alternative 119898119894with respect to the parent criteria 119862119897 can be derived by

120585119894119897 = sum119888119895isin119862119897 120573119894119895 otimes 120573119895sum119888119895isin119862119897 120573119895 = sum119888119895isin119862119897 (120588119894119895 120590119894119895) otimes (120588119895 120590119895)sum119888119895isin119862119897 (120588119895 120590119895)= (120588119894119897 120590119894119897)

(27)

Step 8 In the condition that the weighted rating of thealternative with the parent criteria needs to be comparedbased on (7) the score function can be used as

119904 (120585119894119897) = 119896120588119894119897 minus 119896120590119894119897 + (1 minus 2119896) 10038161003816100381610038161 minus (120588119894119897 + 120590119894119897)1003816100381610038161003816 (28)

51 Deriving the Evaluation Results

Step 1 Construct the individual intuitionistic fuzzy decisionmatrix

Using Table 2 the initial ratings are converted into theintuitionistic fuzzy forms in Tables 3 and 4

Step 2 Construct the initial aggregated intuitionistic fuzzydecision matrix separately

Step 21Weights of the experts are equal then with (11)-(12) the

matrix can be derived as is in the fourth column of Table 5Step 22Weights of the experts are equal with (13) the initial

aggregated intuitionistic fuzzy decision matrix of risk levelof the company can be derived as in the second column ofTable 5

Step 3 Obtain the entropy weightStep 31The entropy weights of evaluators based on the evaluation

of the criteria can be calculated with (14)-(15)

119867119888 (1198901) = 019119867119888 (1198902) = 019119867119888 (1198903) = 011119867119888 (1198904) = 012119867119888 (1198905) = 012119867119888 (1198906) = 013119867119888 (1198907) = 012

(29)

Step 32The entropy weights of evaluators based on the evaluation

of the company can be calculated with (16)-(17)

119867119909 (1198901) = 013

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

(30)

Step 4 Calculate the cross entropy weightStep 41With (18)-(19) the cross entropy weight of evaluators

based on evaluation of the criteria can be derived119862119888 (1198901)=014119862119888 (1198902) = 010119862119888 (1198903) = 019119862119888 (1198904) = 012119862119888 (1198905) = 016119862119888 (1198906) = 013119862119888 (1198907) = 016

(31)

Step 42With (20)-(21) the cross entropy weight of evaluators

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

5 Illustrate Example

In order to control the risks of X Gas Pipeline Company theproposed approach is used to evaluate the risks Seven peopleare invited to evaluate the risk of company and the weight ofcriteria using the linguistic terms in Table 2

51 Deriving the Evaluation Results

Step 1 Construct the individual intuitionistic fuzzy decisionmatrix

Using Table 2 the initial ratings are converted into theintuitionistic fuzzy forms in Tables 3 and 4

Step 2 Construct the initial aggregated intuitionistic fuzzydecision matrix separately

Step 21Weights of the experts are equal then with (11)-(12) the

matrix can be derived as is in the fourth column of Table 5Step 22Weights of the experts are equal with (13) the initial

aggregated intuitionistic fuzzy decision matrix of risk levelof the company can be derived as in the second column ofTable 5

Step 3 Obtain the entropy weightStep 31The entropy weights of evaluators based on the evaluation

of the criteria can be calculated with (14)-(15)

119867119888 (1198901) = 019119867119888 (1198902) = 019119867119888 (1198903) = 011119867119888 (1198904) = 012119867119888 (1198905) = 012119867119888 (1198906) = 013119867119888 (1198907) = 012

(29)

Step 32The entropy weights of evaluators based on the evaluation

of the company can be calculated with (16)-(17)

119867119909 (1198901) = 013

119867119909 (1198902) = 014119867119909 (1198903) = 015119867119909 (1198904) = 017119867119909 (1198905) = 014119867119909 (1198906) = 013119867119909 (1198907) = 014

(30)

Step 4 Calculate the cross entropy weightStep 41With (18)-(19) the cross entropy weight of evaluators

based on evaluation of the criteria can be derived119862119888 (1198901)=014119862119888 (1198902) = 010119862119888 (1198903) = 019119862119888 (1198904) = 012119862119888 (1198905) = 016119862119888 (1198906) = 013119862119888 (1198907) = 016

(31)

Step 42With (20)-(21) the cross entropy weight of evaluators

based on evaluation of the company can be derived

119862119909 (1198901) = 014119862119909 (1198902) = 019119862119909 (1198903) = 014119862119909 (1198904) = 010119862119909 (1198905) = 015119862119909 (1198906) = 013119862119909 (1198907) = 015

(32)

Step 5 Attain the corresponding final weight based on thecross entropy weights and entropy weights

Step 51Let 120572 = 06 120573 = 04 then using (22) the final weight of

evaluators based on the evaluation of criteria can be gotten

1205781119888 = 0161205782119888 = 0141205783119888 = 0161205784119888 = 0121205785119888 = 015

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

Step 52Let 120572 = 06 120573 = 04 then using (23) the final weight

of evaluators based on the evaluation of evaluation of thecompany can be gotten

1205781119909 = 0131205782119909 = 0171205783119909 = 0141205784119909 = 0131205785119909 = 0151205786119909 = 0131205787119909 = 014

(34)

Step 53Let 120579 = 05 based on 120578119896119888 and 120578119896119894 calculate the corre-

sponding final weight 120578119896 which comprehensively considersthe consistency of evaluation indicators of evaluators and theindicator scores by (24)

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible

Mathematical Problems in Engineering 11

Table 6 Weighted evaluation value of the company in the first level

Criteria Weighted evaluation value Score value RankStrategic risk (061 024) 019 FourthMarket risk (055 026) 014 FifthFinancial risk (083 007) 038 SecondOperation risk (090 004) 043 FirstLegal risk (080 009) 035 Third

Overall the risk of gas pipeline operation management isnot high Among the risks the operation risk is higher thanother risks and market risk is lowest

6 Conclusions

As the risks control is important for safeguarding the opera-tion of natural gas pipelines In the paper the evaluation of therisk of natural gas pipeline operation management is studiedFirstly the comprehensive evaluation criteria for the risk ofnatural gas pipeline operation management are constructedIt is constructed from the strategic risk market risk financialrisk operation risk and legal risk aspects Since the ratingsare given in linguistic terms In order to deal with theseratings the intuitionistic fuzzy model is used to represent thelinguistic terms The illustrated example shows the proposedapproach is feasible
