rs 最終組裝排程 (FAS) ? FAS在接到客戶訂單後才安排, 考慮到材料及產(chǎn)能限制。 ? 接單組裝 (AssembletoOrder, ATO):關(guān)鍵零組件根據(jù)客戶需求預(yù)測,事先計(jì)劃、採購、生產(chǎn)、並儲(chǔ)存在倉庫中,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。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。 ?只有在材料主檔中「訂購政策」定為 MRP的材料, MRP系統(tǒng)才會(huì)計(jì)算其材料需求。 ?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。 ? TPOP的技術(shù)用在 MPS和 MRP的計(jì)算上。 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 。 PTF) ?Specific changes allowed within product groups as long as parts are available ?
