The service requirements are scheduled by MRP at the latest start time (LST). The system also calculates the earliest start time (EST) schedule. Schedules are then adjusted between EST and LST to balance the loading and capacity. 精品 資 料網(wǎng) 第三章 再論材料需求規(guī)劃 MPS： 件號 ./需求量 /需求日期 單階 BOM展開，利用計劃訂單發(fā)出 (POR)計算各期
