Abstract
Within an environment of rapid demand fluctuations, production planning changes are frequent and reductions in the plan proposal/revision cycle are sought. Also, an enlarged production planning scale is urgently sought to deal with integrated management of multiple, globally spread production points. To handle these demands, rapid processing of large scale data has become a major theme of Material Requirements Planning (MRP). In this paper a Parallel MRP System, using a loosely connected parallel computer, is described. A newly developed parallel algorithm, data transfer method and load balancing method are used and the system can reduce the 10 hours or more required by a conventional main frame computer for MRP calculations, on the 120,000 item level, to within 9 minutes using a structure with 6 WS servers. The processing speed of the 6 machine structure is 5.98 times the speed of 1 machine and the capabilities increase in a linear fashion. In this way simulated applications are possible for MRP in the workstation integrated management of multiple factories.
