MPS 技術(shù) (2) ? 預(yù)計(jì)可用量 (PAB) 表示若採(cǎi)行 MPS建議的行動(dòng)訊息及計(jì)劃訂單，各期期未的預(yù)計(jì)庫(kù)存量 。 ATP出現(xiàn)在 MPS報(bào)表中的第一期及有在途訂單或計(jì)劃訂單的時(shí)段 。 ? TPOP的技術(shù)用在 MPS和 MRP的計(jì)算上。 ?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。 ?只有在材料主檔中「訂購(gòu)政策」定為 MRP的材料， MRP系統(tǒng)才會(huì)計(jì)算其材料需求。最終產(chǎn)品通常包含標(biāo)準(zhǔn)項(xiàng)目和針對(duì)顧客需求特別設(shè)計(jì)的項(xiàng)目。 ? 接單組裝 (AssembletoOrder, ATO)：關(guān)鍵零組件根據(jù)客戶需求預(yù)測(cè)，事先計(jì)劃、採(cǎi)購(gòu)、生產(chǎn)、並儲(chǔ)存在倉(cāng)庫(kù)中，在接到客戶訂單時(shí)，領(lǐng)出客戶指定的關(guān)鍵零組件，組裝成最終完成品。 MPS Approaches MTO ATO MTS Approach
