The classic MRP work up-to-date with new information on supply chain synchronization Thoroughly revised, Orlicky s Material Requirements Planning, Third Edition reviews the poor business results embedded in most of today s business systems; discusses the core problems causing the results; presents and discusses an alternative pull structure for planning and controlling materials flow; and presents initial results from actual implementations. This new edition reveals the next evolutionary step for materials and supply chain synchronization in the modern manufacturing landscape. This update describes: A solution to a chronic MRP-related problem that plagues many manufacturers: shortages of materials, components that block the smooth flow of work through the plant A competitive edge through strategic lead time reductions Significant reductions in total inventory investment Significant increases in service levels This new edition helps companies tackle three pervasive problems: unacceptable inventory performance; unacceptable service level performance; and high related expenses and waste.
