What Is Capacity Requirements Planning?

Demand Driven Materials Requirement Planning (DDMRP) is a formal planning and execution method designed to complement and upgrade traditional MRP to meet cash-labile, complex, and service-oriented supply and manufacturing environments . DDMRP uses an innovative multi-level pull-type method to plan inventory and raw materials, bringing the company closer to the actual market demand, and promoting better and faster decisions and actions when planning and executing.

Demand-driven MRP

DDMRP is used in 21st century supply chain execution solutions and plans. DDMRP can provide enterprises with sensory capabilities to adapt to and serve today's highly volatile and complex demand chains. The basis of the entire DDMRP is the relationship between the creation, protection, and acceleration of relevant material flows, information, and return on investment. ^[1]

Replenishment + (R +) is a multi-level material and inventory management software with machine learning capabilities, which can promote demand-driven inventory systems to maintain consistency with demand-driven material demand management theory (DDMRP). R + is by far the only software that fully uses DDMRP theory.
