優(yōu)化生產(chǎn)中的物流活動(ppt39頁)-文庫吧在線文庫
【正文】 nt making and assembly. 在傳統(tǒng)的生產(chǎn)中 ,各種生產(chǎn)計(jì)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(jì)劃生產(chǎn)并把成品部件運(yùn)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(jì)劃都必需同時(shí)變化以適應(yīng)同步生產(chǎn) ?) The Push System (cont.)”推動” The Result導(dǎo)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(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 .

Markets are the storage locations for all the parts prior to going to the next operation. “供應(yīng)超市”是為下一道工序儲存所需各種部件的區(qū)域 . ? Markets simply are anized collections of purchased parts and workinprocess. 組建“供應(yīng)超市”只是為了搜集購買的部件和線上的庫存 . ? If parts are already stored in your plant, then you can construct markets. 如果工廠內(nèi)有儲存部件 ,那就可以設(shè)置此體系 . ?) Cautions about Markets 關(guān)于“超市體系
