A fully revised and updated edition of the landmark work on material requirements planning (MRP), Orlicky's Material Requirements Planning, Third Edition focuses on the new rules required to effectively support a manufacturing operation using MRP systems in the twenty-first century. This authoritative resource offers proven solutions that help you gain the competitive edge through strategic lead time reductions, substantial reductions in total inventory investment, and significant increases in service levels.

Building on the pioneering work of Joseph Orlicky, this new edition of the classic text on material requirements planning (MRP) reveals the next evolutionary step for materials and supply chain synchronization in the modern manufacturing landscape.

Orlicky's Material Requirements Planning, Third Edition  explains an alternative pull structure for planning and controlling materials flow, and presents results from actual implementations. This thoroughly updated edition offers comprehensive coverage of MRP, describes the current state of the MRP application, and identifies the fundamental changes required to achieve sustainable success given the current global circumstances and technology options. This state-of-the art guide articulates the next generation of MRP logic—demand driven MRP (DDMRP)—and provides a roadmap for the near and distant future for this critical manufacturing management tool.
