Data
The data that must be considered include:
• The end item (or items) being created. This is sometimes called Independent Demand, or Level "0" on BOM (Bill of materials).
• How much is required at a time.
• When the quantities are required to meet demand.
• Shelf life of stored materials.
• Inventory status records. Records of net materials available for use already in stock (on hand) and materials on order from suppliers.
• Bills of materials. Details of the materials, components and sub-assemblies required to make each product.
• Planning Data. This includes all the restraints and directions to produce the end items. This includes such items as: Routing, Labor and Machine Standards, Quality and Testing Standards, Pull/Work Cell and Push commands, Lot sizing techniques (i.e. Fixed Lot Size, Lot-For-Lot, Economic Order Quantity), Scrap Percentages, and other inputs.
