並列MRPシステムにおける同期管理方式の開発

The application of parallel computing system to MRP (Material Requirements Planning) is essential to achieve a real-time demand forecasting for a whole e-Marketplace near future. The MRP using loosely connected multi-computer system is examined here. New methods of synchronization, load balancing and data access are required to keep high parallel efficiency increasing PE's(Processing Elements). In this paper 2 synchronization methods are proposed. Item synchronization method can keep 96% parallel efficiency for the MRP with 120, 000 items on the 6 PE's structure and can be robust against unbalanced load. The processing speed of the experimental system increases in liner fashion.
