Siemens Digital Industries Software Demand-driven material requirements planning
Demand-driven material requirements planning (DDMRP) is an approach to production planning and production scheduling designed to reduce overstocks and shortages in the manufacturing supply chain. The overall purpose of demand-driven material requirements planning is to overcome the difficulties and shortcomings of applying conventional planning approaches to modern, complex supply chains.
DDMRP diverges from traditional material requirements planning (MRP 1) and make-to-stock (MTS) planning in that it does not rely as heavily on forecasts. It also helps overcome the challenge of long lead times associated with make-to-order (MTO) planning. DDMRP does so by determining where in the supply chain to place strategic inventory buffers, and how large these buffers should be.
The inventory buffers used in demand-driven material requirements planning are also referred to as “decoupling points.” This is because each stock buffer helps disconnect sequential lead times that otherwise accumulate and lengthen delivery time to unacceptable levels. For example, if an inventory buffer is created between an intermediate, complex component and the assembly step that incorporates that component into the finished product, then delivery time for the finished product is decoupled from lead time for the complex component.
The reduced lead times offered by demand-driven material requirements planning help mitigate one of the critical drawbacks of make-to-order and other pull-type operations. Because conventional MTO operations are triggered by sales orders, production operations all occur between the time of the order and the time of delivery. By effectively moving some production operations to the period before the order is received, DDMRP reduces time to delivery.
Demand-driven material requirements planning draws upon some aspects of MRP 1, combining them with elements from other production practices. Specifically, DDMRP employs a lean manufacturing pull method to limit the queues at each operation, and an emphasis on variability reduction from six sigma in manufacturing.
Demand-driven material requirements planning is typically characterized as a five-step process:
A wide array of companies across the manufacturing spectrum are adopting demand-driven material requirements planning because it is tailored to new challenges created by greater product variety, smaller lot and batch sizes, and more complex production operations.
