主生產(chǎn)排程培訓(xùn)講義(完整版)
【正文】 表示預(yù)測低估， MPS取訂單量。 ? MPS是否合理可行決定了 MRP 是不是能發(fā)揮作用。主生產(chǎn)排程 Master Production Scheduling (MPS) MPS的目的 ?協(xié)調(diào)各單位的活動，尤其是產(chǎn)銷之間的配合。 MPS和 PP ?生產(chǎn)規(guī)劃 (PP)是針對產(chǎn)品群或「平均產(chǎn)品」而作； 而 MPS是針對個別完成品而作。在 PTF之後， MPS只考慮預(yù)測量。 ?材料主檔 (item master)中，某項(xiàng)目定義為MPS項(xiàng)目，則所有上階父件均為 MPS項(xiàng)目，均由 MPS系統(tǒng)處理。 MPS Approaches MTO ATO MTS Approach Control point MPS unit Backlog FAS Forecast Cust orders Options End items Product level End prod.
