1、Lean Manufacturing精益精益 Ford Motor China Sourcing OfficeFord Motor China Sourcing OfficeFirst Time Through Calculation FTTDefinition:First Time Through is the percentage of units that plete a process and meet quality guidelines the first time without being scraped,rerun,retested,diverted for off-line
2、 repair,or returned.It is a measure of the quality of the manufacturing process.定义定义:首次通过率是指一次性完成一个生产过程并且满足质量要求的零件的百分率，不包括报废，返工，再测试，下线修理或返回。FTT 用于衡量制造过程的质量。FTT=Units entering process-scrap+reruns+retests+repaired off-line+returns Units entering processFirst Time Through Calculation FTT单工序：单工序：进入数量 =

4、and the release of finished goods for shipment.DTD measures how fast raw materials are converted to finished goods and shipped.It is a measure of the speed of material through the plant,not the speed of the processes.定义:DTD指从原材料到发运产品之间的总运转时间间隔。DTD用于测量原材料转化成成品发运的速度。也就是指材料通过工厂的速度，而不是加工工艺的速度。DTD Single

11、 produce what its customers want,when its customers want it,and in the order the customers use the product.BTS%=Volume%X Mix%X Sequence%Volume Performance:Volume Performance,is the traditional measure that manufacturing has used to monitor their performance to schedule.Mix Performance:The Mix ponent
12、 of BTS measures the percentage of product derivatives/models/types that a plant builds on the right day.Sequence Performance:The sequence ponent of BTS measures the percentage of those products built on the right day that were also built in the right sequence.Process with a sequenced batch of many
13、scheduleBuild to Schedule BTS定义定义:BTS是指在指点的生产日按照正确的生产顺序完成生产方案的比例情况。BTS 反映了工厂能够按照客户的要求完成生产的能力,客户需何种产品,何时需要和客户使用产品的顺序。BTS%=Volume%X Mix%X Sequence%Volume Performance:产量性能用于监控生产方案完成情况。Mix Performance:BTS的混线性能用于测量在厂内制造的产品系/型号/类型等在适当的生产日的完成比率。Sequence Performance:BTS的顺序性能用于测量在适当的生产日按照正确的生产顺序完成生产任务的比率。Pro
