【正文】 dation of lean manufacturing (NOS) is the continual pursuit to eliminate waste. 盡管大家的觀點有些不一樣,但所有人都認(rèn)為NOS的基礎(chǔ)是持續(xù)不斷地減少浪費 Waste is defined as anything that consumes resources or time, but does not add value to the product. 浪費是任何耗費資源或時間,但不增加產(chǎn)品價值的活動,?,Excess Inventory is Waste 多余的庫存是一種浪費,Excess inventory hides problems 多余的庫存會隱藏一些問題,Poor Scheduling 計劃不力,Machine Breakdown 設(shè)備停機(jī),Quality Problems 質(zhì)量問題,Line Imbalance 線內(nèi)不平衡,Long Set Up Time 過長調(diào)整時間,Lack of House Keeping 倉儲管理問題,溝通問題,?,Our goal for materials management in NOS NOS資材管理的目標(biāo),The ideal state is a smooth flow of materials throughout our own factory 理想的狀態(tài)是物料在整個工廠內(nèi)順暢的流動. We want to tie together processes that are separated by large physical distances. 使那些有一定距離而相對分離的生產(chǎn)流程緊密結(jié)合起來 We need to improve communication in regards to material movement. 在物流方面要加強(qiáng)各工序間的溝通,?,The Push System ”推動“生產(chǎn)體系,In traditional manufacturing, various production schedules are released to all processes。 component making and assembly. 在傳統(tǒng)的生產(chǎn)中,各種生產(chǎn)計劃被傳達(dá)到各個工序,部件生產(chǎn)和組裝部門.,?,The Push System (cont.)”推動“,These partmaking processes produce the parts in accordance to their schedules and transport the parts to the next process. 部件生產(chǎn)部門按照收到的計劃生產(chǎn)并把成品部件運送到下一道工序.,?,The Push System (cont.)”推動“,This method makes it difficult to promptly adapt to changes. 這種方法使生產(chǎn)很難迅速對變化作出反應(yīng) Each production schedule must be changed at each process simultaneously. 每個工序的生產(chǎn)計劃都必需同時變化以適應(yīng)同步生產(chǎn),?,The Push System (cont.)”推動”,The Result導(dǎo)致: The company must hold extra inventory among all processes. 公司不得不在各個工序保持額外的庫存 This creates an imbalance of stock between processes. 各工序間的庫存達(dá)不到平衡,?,The Pull System “拉動”生產(chǎn)體系,In contrast, in a PULL SYSTEM, each process will withdraw the parts it needs from the proceeding process. 相反, “拉動”生產(chǎn)體系要求各個工序僅需從上一道工序提取自己所需要的部件.,Supplying Process 供應(yīng)工序,Customer Process 客戶工序,“生產(chǎn)”指示板,“拒收”指示板,?,The Pull System (cont.)”拉動”體系,Since only the finalassembly process can accurately know the necessary timing and quantity of parts required, they are the only ones to receive a schedule. 因為只有制造準(zhǔn)確地了解所需時間和部件數(shù)量,以只要制造收到生產(chǎn)計劃即可.,?,Weekly Schedule每周生產(chǎn)計劃,Final Assembly receives a schedule and pulls from the Market Place. Stitching and Stockfit replenishes the Market Place. 制造接受生產(chǎn)計
