The input components to a Materials Requirement Planning (MRP) system include:
Bill of materials (BOM): This is a detailed list of all the raw materials, components, and
assemblies required to manufacture a product.
Master Production Schedule (MPS): This is a plan for the production of individual end items, specifying the quantities and dates of production.
Inventory status file: This file contains data on the inventory levels of raw materials,
components, and finished goods.
All these components work together in the MRP system to ensure that the right materials are available for production at the right time.
