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)渭兊匾蕾囉?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) .

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 municate schedules. 豐田公司對(duì)調(diào)
