types of production system
- 1. TYPES OF PRODUCTION SYSTEMS PRESENTAION BY- DEEP SHREE
- 2. PRODUCTION A production process consists of activities that are required in transforming an input set (human resources, raw materials, energy, money,information, etc.) 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 PROCESSOR OUTPUT (goods/services)
- 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. LOW HIGH VARIETY CONTINUOUS INTERMITTENT FLOW MASS BATCH JOB PROJECTS PRODUCTION PRODUCTION PRODUC- ORDER TION 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 2.FREQUENT CHANGES IN SETUP MACHINE SETUP 3.DUPLICATION OF 3.LESS MACHINES MACHINES REQUIRED
- 7. ON THE BASIS OF MATERIAL HANDLING AND LABOUR USE CONTINUOUS INTERMITTENT 1.UNSKILLED AS WELL AS 1.HIGHLY SKILLED LABOUR SMALL TEAM OF FORCE SPECIALISED LABOUR FORCE 2.MECHANIZED MATERIAL 2.NOT FEASIBLE TO HANDLING EMPLOY MECHANIZED HANDLING 3.MATERIAL HANDLING 3.MATERIAL HANDLING COST IS LESS COST IS HIGHER 4.INVESTMENT IN 4.NEED FOR INVENTORY IS INVENTORY IS HIGHER MINIMISED
- 8. ON THE BASIS OF OUTPUT PRODUCED- CONTINUOUS INTERMITTENT 1.FEW STANDARD PRODUCTS 1.WIDE RANGE OF PRODUCTS IN LARGE QUANTITIES IN SMALL QUANTITIES 2.OUTPUT ON THE BASIS OF 2.OUTPUT ACCORDING TO ANTICIPATION OF DEMAND ORDER RECEIVED
- 9. DIFFERENCES ON THE BASIS OF MAINTENANCE AND CONTROL EMPLOYED CONTINUOUS INTERMITTENT 1.ABSENCE OF MAINTENNCE 1.NO DANGER OF STOPPAGE MAY INTERRUPT WHOLE OF WHOLE LINE PROCESS 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
