Material Requirements Planning (MRP) is a material planning methodology developed in the 1970's making use of computer technology. MRP provide the ability to proactively manage inventory levels and material flows through a manufacturing facility. The primary features of MRP are the creation of material requirements via exploding the bills of material, and time-phasing of requirements using posted average lead times. MRP II was developed as the second generation of MRP and it features the closed loop system: production planning drives the master schedule which drives the material plan which is the input to the capacity plan. MRP determines when components items are needed and scheduling them to be ready at that time, no earlier or later.
