    • 2. MRRII- Manufacturing resource planning (it evolved into ERP, this does your master schedule and other, not used as much)
  2. MRP II : Overview go of the slide digram
  3. Dependent Demand
    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
  4. 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
  5. the MRP is designed to answer three questions
    • What is needed?
    • How mich is needed?
    • When is it needed?
  6. 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
  7. 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
  8. 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
  9. 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
  10. MRP Processing
    takes the end item requirements specified by the master schedule and explodes them into time phased requirements
