Material Requirements Planning
<application> (MRP) A system for effectively managing material
requirements in a manufacturing process.
Information systems have long been an important part of the manufacturing
environment. In the 1960s, manufacturers developed Material Requirements
Planning (MRP). According to the American Production and Inventory Control
Society, Inc. (APICS), MRP is a set of techniques that uses bill of material
data, inventory data, and the master production schedule to calculate
requirements for materials. It makes recommendations to reorder materials.
Furthermore, because it is time-phased, it makes recommendations to reschedule
open orders when due dates and need dates are not in phase. Time-phased MRP
begins with the items listed on the Master Production Schedule and determines
the quantity of all components and materials required to fabricate those items
and the date that the components and material are required. Time-phased MRP is
accomplished by exploding the bill of material, adjusting for inventory
quantities on hand or on order and offsetting the net requirements by the
appropriate lead times.
