【正文】 Material Movement in a Lean Manufacturing Operation 優(yōu)化生產(chǎn)中的物流活動(dòng),Total Systems Development 全體系生產(chǎn)提高,?,JIT生產(chǎn)(準(zhǔn)時(shí),準(zhǔn)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(zhǔn)時(shí),準(zhǔn)量供應(yīng)? Does it mean JIT Production? 準(zhǔn)時(shí),準(zhǔn)量生產(chǎn)?,?,So, what is JustInTime? 那么,什么是準(zhǔn)時(shí)準(zhǔn)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(shí)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(shuō)明: 在生產(chǎn)成品鞋的時(shí)候:制鞋所必需的部件(鞋幫和鞋底)要準(zhǔn)時(shí),準(zhǔn)量,準(zhǔn)型號(hào)地到達(dá)制造車(chē)間.,?,If we achieve JIT: 如果我們做到準(zhǔn)時(shí),準(zhǔn)量生產(chǎn):,Unnecessary inventories will be eliminated. 不必要的庫(kù)存就會(huì)消除 Stores and warehouses will not be needed. 儲(chǔ)存區(qū)和倉(cāng)庫(kù)也可以取消 Material carrying costs will be diminished. 資材搬運(yùn)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：?jiǎn)渭兊匾蕾?lài)計(jì)劃生產(chǎn)的方法,使所有工序同步生產(chǎn)，并不能完全實(shí)現(xiàn)所有環(huán)節(jié)的準(zhǔn)時(shí)，準(zhǔn)量生產(chǎn).,?,Weekly Schedule每周生產(chǎn)計(jì)劃,Typically, one control operation receives the customers’ orders and disseminates schedules. 通常，生產(chǎn)控制部門(mén)接受客戶(hù)定單，然后制訂并傳達(dá)計(jì)劃.,Production Control 生產(chǎn)控制,?,Weekly Schedule每周生產(chǎn)計(jì)劃,Production Control 生產(chǎn)控制,The problem comes when a change is made either because the order changes or equipment breaks down. 但是當(dāng)定單有變化或設(shè)備出現(xiàn)問(wèn)題的時(shí)候，就會(huì)發(fā)生一些問(wèn)題：,庫(kù)存,庫(kù)存,庫(kù)存,庫(kù)存,?,The result is excess inventory… 結(jié)果是導(dǎo)致過(guò)多的庫(kù)存…,…within the plant as WorkInProcess …在本車(chē)間工序內(nèi)積壓過(guò)多的庫(kù)存 …suppliers sending in parts that are not needed …上一道工序發(fā)來(lái)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(lái)堆放材料 Need expeditors to satisfy the changes in schedule. 需要人力和時(shí)間投入來(lái)改變生產(chǎn)計(jì)劃 Run overtime to make up parts that we now need. 用加班時(shí)間來(lái)生產(chǎn)現(xiàn)在所需部件,?,Toyota rethought how to communicate schedules. 豐田公司對(duì)調(diào)整生產(chǎn)計(jì)劃做了改進(jìn):,Toyota discovered a different way to manage their schedule, 豐田使用不同的方法來(lái)制訂調(diào)整生產(chǎn)計(jì)劃 They stopped trying to guess what the customer will want. 他們并不去猜想客戶(hù)的需求,?,Instead相反,Each department had installed a small inventory of each product. 每個(gè)車(chē)間都保持少量的庫(kù)存 Downstream proc
