Focus Workshop - Material Requirements Planning

One-day Workshop

Click here to see our Focus Workshop Series schedule.

Material requirements planning is a set of techniques that uses bill of material data, inventory data and the master production schedule to calculate requirements for materials. Time-phased MRP begins with the items listed on the master production schedule (MPS) and determines (1) the quantity of all components and materials required to fabricate those items, and (2) 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.

This one-day workshop will focus on Basics of MRP and Managing with MRP.
