Material Movement in a Lean Manufacturing Operation  优化生产中的物流活动 Total Systems Development 全体系生产提高 JIT生产(准时,准量生产): So, what is Just-In-Time?那么,什么是准时准量生产? The concept of producing the necessary units in the necessary quantities at the necessary time is described by the short-phrase “Just-In-Time”. JIT生产是:在必需时间内生产必需数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. 举例说明: 在生产成品鞋的时候:制鞋所必需的部件(鞋帮和鞋底)要准时,准量,准型号地到达制造车间. If we achieve JIT: 如果我们做到准时,准量生产: Unnecessary inventories will be eliminated. 不必要的库存就会消除 Stores and warehouses will not be needed. 储存区和仓库也可以取消 Material carrying costs will be diminished. 资材搬运成本降低 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：单纯地依赖计划生产的方法,使所有工序同步生产，并不能完全实现所有环节的准时，准量生产. Typically, one control operation receives the customers’ orders and disseminates schedules.通常，生产控制部门接受客户定单，然后制订并传达计划. The problem comes when a change is made either because the order changes or equipment breaks down.但是当定单有变化或设备出现问题的时候，就会发生一些问题： The result is excess inventory…结果是导致过多的库存… Additionally另外, Toyota rethought how to communicate schedules.丰田公司对调整生产计划做了改进: Instead相反..
