Abstract

Manufacturing planning and control (MPC) systems have existed since the earliest days of the industrial revolution. To gain a historical perspective, it is useful to look at the evolution of these systems. Five major stages were involved: reorder point (ROP) systems, materials requirement planning (MRP) systems, manufacturing resource planning (MRP-II) systems, MRP-II with manufacturing execution systems (MES), and enterprise resource planning systems (ERP) with MES. When examined in detail, each stage represents the next logical step in manufacturing philosophy and technological innovation over the preceding stage.
