【文章內容簡介】 em ”推動“生產體系 ? In traditional manufacturing, various production schedules are released to all processes。 ponent making and assembly. 在傳統(tǒng)的生產中 ,各種生產計劃被傳達到各個工序 ,部件生產和組裝部門 . 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. 部件生產部門按照收到的計劃生產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. 這種方法使生產很難迅速對變化作出反應 ? Each production schedule must be changed at each process simultaneously. 每個工序的生產計劃都必需同時變化以適應同步生產 The Push System (cont.)”推動” The Result導致 : – The pany 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. –各工序間的庫存達不到平衡 The Pull System “拉動”生產體系 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 . B A “ production” kanban “ withdrawal” kanban Product部件 Product部件 Market 供應超市 Supplying Process 供應工序 Customer Process 客戶工序 “生產”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. 因為只有制造準確地了解所需時間和部件數(shù)量 ,以只要制造收到生產計劃即可 . Assembly Stockfit準備 Stitching縫紉 Assembly制造 Shipping裝船 Weekly Schedule每周生產計劃 Final Assembly receives a schedule and pulls from the Market Place. Stitching and Stockfit replenishes the Market Place. 制造接受生產計劃 ,并借助“供應超市”拉動生產 .縫紉和準備向“供應超市”補充部件 . Production Control 生產控制 The Pull System (cont.)”拉動”體系 With the schedule, the finalassembly goes to the supplying departments and withdraws what parts are needed. 根據(jù)生產計劃 ,制造到供應車間去提取所需部件 . The Pull System (cont.)”拉動“生產 The preceding operation then produces the replacements of the parts withdrawn by the subsequent process. 這樣 ,前一道工序開始生產被下一道工序提走的部件以補充所需 . B Assembly 制造 Stitching 縫紉 A “ production” kanban “ withdrawal” kanban Product 部件 Product
