It is a quantitative relationship between output and input.
Is there any formula..?
Productivity = total output/total input which is identical to total results achieved/total resources consumed or effectiveness/efficiency.Purposes of productivity measurementAdopt to Technology changes.Improve EfficiencyReal cost saving.Benchmarking production process.Living standards.
Measurements of productivity:(single factor)Types of output measuresType of input measuresLabour Capital Capital and labourGross outputLabour productivity(based on grossoutput)Capital productivity(based on grossoutput)Capital-labour MFP(based on grossoutput)Value addedLabour productivity(based on valueadded)Capital productivity(based on valueadded)Capital-labour MFP(based on valueadded)Multi factor:Capital and labourCapital, labour andintermediate inputs(energy, materials,services)Capital-labour MFP(based on gross output)multifactor productivityCapital-labour MFP(based on value added)Multifactor productivity (MFP) measuresIntroduction to CADWhat is CIM..? Computer Integrated Manufacturing (CIM) encompasses the entire range of product development and manufacturing activities with all the functions being carried out with the help of dedicated software packages.
What is CAD.?Computer-Aided Design (CAD) is the technology - creation, modification, analysis, and optimization of a design. major elements of a CIM system

Types of automation..?Fixed automationFlexible automationProgrammable automationSteps in automationStandardization of work.Job planningCNC programming.Raw material procurement.Workflow through shop.Palletisation and presetting.Automatic loading and unloading.System integration and options.Points favoring to automationMitigating risk and uncertaintyImproved working conditionsOne time investment.Elimination of human errors.Improved and standardized productivity.
Points against the automationNeeds Huge capital investment.Capability to adopt to the changes is less.No scope for customization.Resistance to changeIt leads to unemployment.Designing production system at shop floor:What is production?The processes andmethodsemployedto transformtangibleinputs (raw materials, semi finishedgoods, orsubassemblies) andintangibleinputs (ideas,information,knowledge) into goods orservices.
What is production system.?Manufacturingsubsystemthat includes allfunctionsrequiredtodesign,produce, distribute, andservicea manufacturedproduct.
What is considered to be shop floor..?TheShop floorliterally is thefloorof afactory(machine shop) where people work on machines, or the space in aretailestablishment where goods are sold to customers.Goals of designing PS @ SFBest qualityMaximizing the valueLowest cost.Minimizing wastage.Supporting organizational goals
Elements to be considered for PS@SFShortest process timeRight technology.Knowledge of the workers.Quantity to be produced.SafetyTypes of production resources.Optimum inventory levels to maintain.15
Work instructions:What it means..?A set of instructions for performing a task or for following a procedure.
How are they produced?Manually, with desktop automation tools for small businesses with low product complexity; and Automatically or semi-automatically using PLM (product life-cycle management) and PDM (product data management) applications.
Continued.Why should biz. have work instructions..........?
Have some consistency in serving your customers.When you have a frequent turnover of part time helpers.A ready reference for training new employees and for potential promotions.
Essentials of work instructionsMainly there are five essentials which are as follows:
Retaining the Focus to the Worker.Credible: Workers Trust Them.Clear: Workers Understand Them.Accessible: Workers Can Get To ThemConsistent: They Match Worker Training"Confidence comes not from always being right but from not fearing to be wrong."
