【正文】 Lean Manufacturing 精益 生產(chǎn) Ford Motor China Sourcing Office 福特汽車中國采購中心 經(jīng)理人世界 制造業(yè)頻道 First Time Through Calculation (FTT) Definition: 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 offline repair, or returned. It is a measure of the quality of the manufacturing process. 定義 : 首次通過率是指一次性完成一個(gè)生產(chǎn)過程并且滿足質(zhì)量要求的零件的百分率， 不包括報(bào)廢，返工，再測試，下線修理或返回。 FTT 用于衡量制造過程的質(zhì)量。 FTT= Units entering process(scrap+reruns+retests+repaired offline+returns) Units entering process 經(jīng)理人世界 制造業(yè)頻道 First Time Through Calculation (FTT) 單工序： 進(jìn)入數(shù)量 = 1000 報(bào)廢 = 10 返工 = 15 測試 = 5 下線修理 = 0 FTT% = 1000 （ 10+ 15+ 5+ 0） 1000 FTT% = % 多工序： FTT (工序 1) = % FTT (工序 2) = % FTT (工序 3) = % 最終檢驗(yàn) (工序 4) = % 總 FTT% = % X % X % X % Total FTT% = % 經(jīng)理人世界 制造業(yè)頻道 Total Dock To Dock Calculation (DTD) Definition: Dock to Dock is the elapsed time between the unloading of raw materials 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. 定義 : DTD指從原材料到發(fā)運(yùn)產(chǎn)品之間的總運(yùn)轉(zhuǎn)時(shí)間間隔。 DTD用于測量原材料轉(zhuǎn)化成成品發(fā)運(yùn)的速度。也就是指材料通過工廠的速度，而不是加工工藝的速度。 DTD (Single Operation) = Total Units of Control Part End of line Rate DTD (Multiple Operation)= DTD(OP 1)+DTD(OP 2)+… End of line Rate 經(jīng)理人世界 制造業(yè)頻道 Total Dock
