Bringing MRP into the 21st Century
MRP, first developed in limited fashion in the 1950s and 60s, really took off in the 1970s, when computer systems enabled widespread adoption and APICS undertook the “MRP Crusade” to popularize it.
MRP morphed in the late 1970s and 80s into MRP II and ultimately ERP. But the heart of today’s ERP systems, at least in the manufacturing sector, is still the MRP processing logic that is essentially unchanged since the 1970s.
Demand Driven MRP
Demand Driven Material Requirements Planning is an innovative multi-echelon pull methodology to plan inventories and materials.
It enables a company to build more closely to actual market requirements and promotes better and quicker decisions and actions at the planning and execution level.
DDMRP was introduced to the world in the book Orlicky’s Material Requirements Planning, Third Revised Edition by Carol Ptak and Chad Smith.
