Production Planning and Control Flashcards
What are the inputs for materials requirements planning?
What to make, how much, by when?
What’s is in stock?
What parts and materials does the parts require
What are the outputs for materials requirements planning?
Purchasing requirements
Work orders
What is BOM?
Bill of materials - file to break down a product into its constituent components
What is a push system planning technique?
issuing orders to shop floor via plan. Little feedback in system assumes system can manufacture orders before production. Daily management of shop floor during production.
What is included in the BOM?
Quantity, lead time, type - bought-in or manufactured, components linked by their sub-assembly parts
What is closed loop MRP(II)?
Wider concept - includes, business, marketing, production and resource requirements planning.
What is JIT?
Just-In-Time - aims to reduce waste i.e. something that adds to the cost but no value. Only produce amount needed for that specific time.
What is kanban concept?
JIT system where bins or ‘kanbans’ fill up with parts. Machine only is active when its kanban bin is not full. Therefore parts are being ‘pulled’ through the system.
What is OPT?
optimised production technology - pull system that meets the demand of a bottleneck system.. Time lost at bottleneck is time lost by the whole system, time saved that is not the bottleneck is an illusion.
the sum of the local optimisations is not equal to the optimisation of the whole system
What is distributed planning and control?
used to manage multiple production facilities. Geographical positions of facilities may be different. Cooperative working structure rather than top down.
What is heterarchical structure?
equal players i.e. individuals factories have their own control.
What is semi heterarchical structure?
Similar to heterarchical structure but their is a central oversight to make sure business values are kept etc.
