Material Requirement Planning
From PLMpedia
Manufacturing planning and inventory control aimed at efficient management of product manufacturing. MRP-systems enable to simultaneously achieve the following goals:
- Check that materials or products are available for manufacturing or supplying to the customers
- Manage the lowest possible level of inventory
- Plan manufacturing processes, supplies and procurement
At the input of such systems there are a Master Production Schedule (MPS), inventory data (information on availability of raw materials and semi-finished products), a Bill of Materials (BOM) and information on planning (routing, labor and machine tool standards). At the output– a recommended production plan (detailed information about the starting time and the end time of each operation in terms of the product components) and a recommended procurement plan for the raw materials and semi-finished products. MRP technology was developed at the end of 1960s and has been further extended to a more general technology of Manufacturing Resource Planning (MRP II) and the concept of Enterprise Resource Planning (ERP).
