1. PRESENTAION BY- DEEP SHREE TYPES OF PRODUCTION SYSTEMS
2. PRODUCTION A production process consists of activities that
are required in transforming an input set (human resources, raw
materials, energy, money,information, e tc.) to valuable outputs
with the help of processors. 3. Production system A production
system converts inputs into outputs with the help of processors A
generalised production system can be represented as:- INPUT OUTPUT
(goods/services) PROCESSOR 4. Types of production systems
Classification on the basis of output Three bases considered- 1.
Variety 2. Uniformity 3. Volume per output type o Two types -
a)continuous b)intermittent 5. CONTINUOUS INTERMITTENT FLOW
PRODUCTION MASS PRODUCTION BATCH PRODUC- TION JOB ORDER PROJECTS
LOW HIGH VARIETY HIGH LOW UNIFORMITY HIGH LOW VPOT 6. DIFFERENCE
BETWEEN CONTINUOUS AND INTERMITTENT SYSTEMS ON THE BASIS OF
MACHINERY CONTINUOUS INTERMITTENT 1.SPECIFIC MACHINERY
1.GENERALISED MACHINERY 2.PERMANENT MACHINE SETUP 2.FREQUENT
CHANGES IN MACHINE SETUP 3.DUPLICATION OF MACHINES 3.LESS MACHINES
REQUIRED 7. ON THE BASIS OF MATERIAL HANDLING AND LABOUR USE
CONTINUOUS INTERMITTENT 1.UNSKILLED AS WELL AS SMALL TEAM OF
SPECIALISED LABOUR FORCE 1.HIGHLY SKILLED LABOUR FORCE 2.MECHANIZED
MATERIAL HANDLING 2.NOT FEASIBLE TO EMPLOY MECHANIZED HANDLING
3.MATERIAL HANDLING COST IS LESS 3.MATERIAL HANDLING COST IS HIGHER
4.INVESTMENT IN INVENTORY IS HIGHER 4.NEED FOR INVENTORY IS
MINIMISED 8. ON THE BASIS OF OUTPUT PRODUCED- CONTINUOUS
INTERMITTENT 1.FEW STANDARD PRODUCTS IN LARGE QUANTITIES 1.WIDE
RANGE OF PRODUCTS IN SMALL QUANTITIES 2.OUTPUT ON THE BASIS OF
ANTICIPATION OF DEMAND 2.OUTPUT ACCORDING TO ORDER RECEIVED 9.
DIFFERENCES ON THE BASIS OF MAINTENANCE AND CONTROL EMPLOYED
CONTINUOUS INTERMITTENT 1.ABSENCE OF MAINTENNCE MAY INTERRUPT WHOLE
PROCESS 1.NO DANGER OF STOPPAGE OF WHOLE LINE 2.CONTROLLING IS
SIMPLER 2.CONTROLLING IS COMPLEX 10. TYPES OF CONTINUOUS PRODUCTION
SYSTEM 1.FLOW TYPE Output cannot be segregated into different units
High degree of uniformity Output cannot be measured directly
Example-power plant 11. 2.MASS PRODUCTION Straight line flow of
materials Output of one stge normally becomes input for another
Output visible in form of identical units Standardised output
produced in large quantities PROBLEMS 1. Balancing of production
lines 2. Machine maintenance 3. Raw materials supply Example sugar
production 12. Types of intermittent production systems 1.BATCH
PRODUCTION SYSTEM- Variety of products are made in small quantities
Various products compete for share of machines Outputs are
aggregated in form of batches Batches may comprise of similar or
dissimilar outputs PROBLEMS 1. Machine-job allocation problem 2.
Determination of economic batch quantity 3. Scheduling and
sequencing of operations Example electrical goods 13. 2.JOB-ORDER
PRODUCTION SYSTEM Does not has its own standard product but accepts
whatever customer orders come in Output identifiable in terms of
specific job order Material flow is very complex PROBLEMS 1.
Determination of the sequence of processing Example tailor shop 14.
3.PROJECT PRODUCTION SYSTEM Project is a temporary endeavour having
a defined beginning and end ;undertaken to meet unique goals and
objectives Project is non repetitive This type of production system
uses resources on different projects Product remains fixed and
manpower and facilities put work on it PERT/CPM can be used for
planning and control in this case 15. THANK YOU
