【正文】 ?) Material Movement in a Lean Manufacturing Operation 優(yōu)化生產(chǎn)中的物流活動 Total Systems Development 全體系生產(chǎn)提高 ?) JIT生產(chǎn) (準時 ,準量生產(chǎn) ): What is meant by the term, “JustInTime”? JIT生產(chǎn)意味著什么 ? – Does it mean JIT Supply? 準時 ,準量供應(yīng) ? – Does it mean JIT Production? 準時 ,準量生產(chǎn) ? ?) So, what is JustInTime? 那么 ,什么是準時準量生產(chǎn) ? The concept of producing the necessary units in the necessary quantities at the necessary time is described by the shortphrase “JustInTime”. JIT生產(chǎn)是 :在必需時間內(nèi)生產(chǎn)必需數(shù)量的必需部品的概念 . ?) For example…. In building shoes: The necessary subassemblies of the proceeding process (uppers and bottoms) should arrive at the assembly line at the time needed in the amounts needed. 舉例說明 : 在生產(chǎn)成品鞋的時候 :制鞋所必需的部件 (鞋幫和鞋底 )要準時 ,準量 ,準型號地到達制造車間 . ?) If we achieve JIT: 如果我們做到準時 ,準量生產(chǎn) : ? Unnecessary inventories will be eliminated. 不必要的庫存就會消除 ? Stores and warehouses will not be needed. 儲存區(qū)和倉庫也可以取消 ? Material carrying costs will be diminished. 資材搬運成本降低 ?) However…. To rely solely on a central planning approach that instructs the production schedules to all processes simultaneously is not likely to result in a JIT process for all operations. 但是 ：單純地依賴計劃生產(chǎn)的方法 ,使所有工序同步生產(chǎn)，并不能完全實現(xiàn)所有環(huán)節(jié)的準時，準量生產(chǎn) . ?)

The result is excess inventory… 結(jié)果是導(dǎo)致過多的庫存 … …within the plant as WorkInProcess …在本車間工序內(nèi)積壓過多的庫存 …suppliers sending in parts that are not needed …上一道工序發(fā)來的并不需要的部件 ?) Additionally另外 , ? We need extra floor space to store the material. 我們需要額外的空間來堆放材料 ? Need expeditors to satisfy the changes in schedule. 需要人力和時間投入來改變生產(chǎn)計劃 ? Run overtime to make up parts that we now need. 用加班時間來生產(chǎn)現(xiàn)在所需部件 ?) Toyota rethought how to municate schedules. 豐田公司對調(diào)整生產(chǎn)計劃做了改進 : ? Toyota discovered a different way to manage their schedule, 豐田使用不同的方法來制訂調(diào)整生產(chǎn)計劃 ? They stopped trying to guess what the customer will want. 他們并不去猜想客戶的需求 ?) Instead相反 .. ? Each depar
