- 7. PRODUCTION PLANNING AND CONTROL (PPC) PRODUCTION: that transformation of raw materials to finished goods. PLANNING: looks ahead, anticipates possible difficulties and decides in advance as to howthe production, best, be carried out. CONTROL: phase makes sure that the programmed production is constantly maintained.

- 9. Production planning and Control • Production planning is an activity that is performed before the actual production process takes place. • It involves determining • the schedule of production, • sequence of operations, • economic batch quantities, and • the dispatching priorities for sequencing of jobs. • Production control is mainly involved in implementing production schedules and is the corollary to short-term production planning or scheduling. • It includes • initiating production, • dispatching items, • progressing and • then finally reporting back to production planning.
- 10. Objectives of production planning and control • 1. To plan production facilities in the best possible manner along with the proper systematic planning of production activities. • 2. Providing men, machines, materials etc. of right quality, quantity and also providing them at the right time forms a very important factor. • 3. To inform, about the difficulties or the various awkward positions expected to crop up later, to the management beforehand.
- 11. PRODUCTION SYSTEM System is a whose function is to convert a set of inputs into a set of desired outputs.
- 12. PRODUCTION PLANNING Given a specific process planning, process technologies and production conditions predetermine varieties, quantities, qualitiy,and scheduled of products to be produced according to market demand of products..

- 14. TIME DIMENSIONS Long Range Planning; is done annually and focus on a planninghorizon greater than one year. Medium Range Planning; usually covers a period from 6 months to 18 months, with monthly or sometimes quarterly time increments. Short Range Planning; covers a period fromone day or less to six months, with weekly time increment usually.
- 16. PRODUCTION PLANNING PLANNING That may be defined as the technique of foreseeing every step in a long series ofseperate operations. Each step to be taken at the right time, and in the right place and each operation to be performed in maximum efficiency.
- 17. PRODUCTION PLANNING ROUTING Under this operations , their path and sequenceare established. The main aim of routing; determine the best and cheapest sequence of operations and to ensurethat this sequence is strictly followed.
- 18. PRODUCTION PLANNING Routing procedure involves following different activities; An analysis of the article to determine whatto make and what to buy To determine the quality and type ofmaterial Determining the manufacturing operations and their sequence An analysis of cost of the article Determination of scrap factors
- 19. PRODUCTION PLANNING SCHEDULING It mainly concerns with time element and priorities of a job. The pattern of scheduling differs from one jobto another which is explained asbelow: Production Schedule Master Schedule Manufacturing Schedule
- 20. PRODUCTION PLANNING LOADING Defined as the relationship between loadand capacity, so as to assign the work for the production. Capacity: the time available for work atwork centres expressed in machine hours or in man hours. Load: to assign work to the capacity availableat particular work centres. It includes the assignment of the work tothe operators at their machines or work places.
- 21. PRODUCTION PLANNING Loading determines; who will do the workas routing determines; where and scheduling determines; when it shall be done.
- 22. PLANNING PHASE PRIOR PLANNING Forecasting Type, Quantitiy,Quality Product Design Specifications,Bill of Materials Order Writing To undertake a particular job.
- 23. PLANNING PHASE ACTIVE PLANNING Process Planning and Routing Economic Process, How to do, Where to Work Materials and Tools Control Requirements, Controls Loading Assignment of Work, Manpower, Machinery Scheduling Time Phase, Sequence of Work
- 24. PLANNING PHASE ACTION PHASE Dispatching Ordering to start the working CONTROL PHASE Progress Reporting Data Reporting, Performance Comparison Corrective Phase Expediting, Replanning
- 27. PRODUCTION CONTROL Production control; is the process of planning production in advance of operations, establishing the extract route of each individual item part or assembly, setting, starting and finishing for each important item, assembly the finishing production and releasing the necessary orders as well as initiating thenecessary follow-up to have the smooth function of the enterprise.
- 28. PRODUCTION CONTROL DISPATCHING Involves issue of production orders for startingthe operations. Movement of materials to different workstations Movement of tools and fixtures necessary foreach operation Beginning of work on each operation
- 29. PRODUCTION CONTROL et DISPATCHING Recording of time and cost involved ineach operation Movement of work from one operation toanother in accordance with the routeshe Inspecting or supervision of work
- 30. PRODUCTION CONTROL FOLLOW UP It includes delays or deviations fromthe production plans. It helps to reveal detects in routing and scheduling, misunderstanding of orders and instruction, under loading or overloading ofwork.
- 31. PRODUCTION CONTROL INSPECTION To ensure the quality of goods. It can berequired as effective agency of production CORRECTIVE MEASURES involve any of those activities of adjusting the route, rescheduling of work changing the workloads, repairs and maintenance of machinery or equipment, control over inventories of thecause of deviation is the poor performance of the employees
- 32. MATERIAL REQUIREMENT PLANNING (MRP) PHILOSOPHY MRP- Materials should be expedited when their lack would delay the overall production schedule. AIM of MRP Renawal of products inventory To meet customer orders
