精益生产（Lean Production）

一、精益生产（Lean Production,Lean Manufacturing）:是以没有任何库存、时间、空间、劳动力浪费为目标，持续推行价值链整体改善的一种生产方式。

二、基于消除浪费的精益生产思想：1.七大浪费 2.效率速度 3.减少库存

三、精益思想：

价值（Value):站在客户的立场上

价值流（Value Stream):从接单到发货过程的一切活动

流动（Flow):象畅通的河水一样流动

需求拉动（Demand Pull):BTR-按需生产

完美（Perfact):没有任何事情是完美的，要不断改进。

结论：降低成本，改善质量，缩短生产周期

三、消除七种浪费

1、返工（Correction)

2、过量生产（OverProduction)

3、搬运（Conveyance)

4、多余动作（Motion)

5、等待(Waiting)

6、库存(Iventory)

7、非增值过程（Processing)

四、与six sigma的区别：

Both the Lean and the Six Sigma methodologies have proven over the last twenty years that it is possible to achieve dramatic improvements in cost, quality, and time by focusing on process performance. Whereas Six Sigma is focused on reducing variation and improving process yield by following a problem-solving approach using statistical tools, Lean is primarily concerned with eliminating waste and improving flow by following the Lean principles and a defined approach to implement each of these principles.

The impressive results companies such as Toyota, General Electric, Motorola, and many others have accomplished using either one of them have inspired many other firms to follow their example. As a result, most companies have either a Lean or Six Sigma program in place. However, using either one of them alone has limitations: Six Sigma will eliminate defects but it will not address the question of how to optimize process flow; and the Lean principles exclude the advanced statistical tools often required to achieve the process capabilities needed to be truly 'lean'. Therefore, most practitioners consider these two methods as complementing each other. And while each approach can result in dramatic improvement, utilizing both methods simultaneously holds the promise of being able to address all types of process problems with the most appropriate toolkit. For example, inventory reduction not only requires reducing batch sizes and linking operations by using Lean, but also minimizing process variation by utilizing Six Sigma tools.-质量-SPC ,Therefore, many firms are looking for an approach that allows to combines both methodologies into an integrated system or improvement roadmap. However, the differences between the Six Sigma and Lean are profound:-质量-SPC ,six sigma,TS16949,MSA,FMEA jM {.sa(\Xp7[
