MRP II : Overview go of the slide digram
demand for items that are sub assemblies or components parts to be used in the production of finished goods
- Dependent demand tends to be sporadic or "lumpy"
- Large quantities are used at specific points in time eith little
Material requrements plannings MRP
A computer based information system that translates master schedules requirement for end items into time phased requirements for subassemblies, components , and raw materials
the MRP is designed to answer three questions
- What is needed?
- How mich is needed?
- When is it needed?
Bill of materials
A listing of all of the assemblies, sub assemblies, parts and raw materials needed to produce one unit or end itmem of product example this is the recipe to make a pie, order, how much we need, steps
MRP Inputs: Master Schedule
- Master Schedule
- One of the three primary inputs in MRP; states which ends items are to be produced, when these are needed, and in what quantities
- Managers like to plan far enough into the future so they have reasonable estimates of upcoming demands
- The master schedule should cover a perod that is at least equivalent to the cumulative lead time
Cumulative lead time
The sum of the lead time that sequential phases of a process require, from ordering of parts or raw materials to completion of final assembly
Low level coding
restructuring the bill of material so that multiple occurrences of a component all coincide with the lowest level at which the component occurs
takes the end item requirements specified by the master schedule and explodes them into time phased requirements
