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流程緊密結合起來 ? We need to improve munication in regards to material movement. 在物流方面要加強各工序間的溝通 The Push System ”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 .
