types of production system types of production system Presentation Transcript

  • TYPES OF PRODUCTION SYSTEMS PRESENTAION BY- DEEP SHREE
  • PRODUCTIONA production process consists ofactivities that are required intransforming an input set (humanresources, raw materials, energy,money,information, etc.) to valuableoutputs with the help of processors.
  • 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)
  • Types of productionsystems Classification on the basis of outputThree bases considered-1. Variety2. Uniformity3. Volume per output typeo Two types -a)continuousb)intermittent
  • LOW HIGH VARIETY CONTINUOUS INTERMITTENTFLOW MASS BATCH JOB PROJECTSPRODUCTION PRODUCTION PRODUC- ORDER TION HIGH LOW UNIFORMITY HIGH LOW VPOT
  • DIFFERENCE BETWEEN CONTINUOUS ANDINTERMITTENT SYSTEMS ON THE BASIS OF MACHINERYCONTINUOUS INTERMITTENT1.SPECIFIC MACHINERY 1.GENERALISED MACHINERY2.PERMANENT MACHINE 2.FREQUENT CHANGES INSETUP MACHINE SETUP3.DUPLICATION OF 3.LESS MACHINESMACHINES REQUIRED
  •  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
  •  ON THE BASIS OF OUTPUT PRODUCED-CONTINUOUS INTERMITTENT1.FEW STANDARD PRODUCTS 1.WIDE RANGE OF PRODUCTSIN LARGE QUANTITIES IN SMALL QUANTITIES2.OUTPUT ON THE BASIS OF 2.OUTPUT ACCORDING TOANTICIPATION OF DEMAND ORDER RECEIVED
  •  DIFFERENCES ON THE BASIS OF MAINTENANCE AND CONTROL EMPLOYEDCONTINUOUS INTERMITTENT1.ABSENCE OF MAINTENNCE 1.NO DANGER OF STOPPAGEMAY INTERRUPT WHOLE OF WHOLE LINEPROCESS2.CONTROLLING IS SIMPLER 2.CONTROLLING IS COMPLEX
  • TYPES OF CONTINUOUSPRODUCTION SYSTEM1.FLOW TYPE Output cannot be segregated into different units High degree of uniformity Output cannot be measured directly Example-power plant
  • 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 PROBLEMS1. Balancing of production lines2. Machine maintenance3. Raw materials supply Example – sugar production
  • Types of intermittentproduction systems1.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 PROBLEMS1. Machine-job allocation problem2. Determination of economic batch quantity3. Scheduling and sequencing of operations Example – electrical goods
  • 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 PROBLEMS1. Determination of the sequence of processing Example – tailor shop
  • 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
