Data should be collected at the same time which best represents the operating pattern of a product line 衡量指標 DTD *如何做 ? .降低原材料庫存 ? .降低安全庫存量 ? .提高進料頻度 衡量指標 DTD *如何做 ? ? . 降低成品庫存 ? ? .降低安全庫存 ? ? .提高交貨頻度 衡量指標 DTD *如何做 ? .減少在制品 /制程高效率化 ? .目視化 以及 防誤措施 ? .一個流 小批量 ? .作業(yè)依排程生產(chǎn) ? .推展全員生產(chǎn)性保養(yǎng) ? .縮短轉(zhuǎn)換時間 衡量指標 DTD *降低總 DTD 時間 . 制程工程分析改善物流效率 . 消除停滯減少搬運 . 制程作業(yè)分析改善 . 降低周期時間 .消除不良 . 提高首次合格率 .排除稼動損失 . 提高總合設備效率 .善用價值流圖析 衡量指標 DTD *降低總 DTD 時間 ? .DTD從價值流圖析能作用明確有效展現(xiàn) ? .應用工業(yè)工程分析改善效率 並 進行時間縮短改善 （ 時間） 是 各 企業(yè)公司同樣擁有之唯一 等量資源 衡量指標 DTD ? 單作業(yè) DTD= 復合作業(yè) DTD= 總管制數(shù) 線 末速率 DTD作業(yè) 1+DTD作業(yè) 2+DTD作業(yè) 3 線 末速率 Total Dock To Dock Calculation ? (Single Operation ) DTD = (Multiple Operation) DTD= Total Units of Control Part End of Line Rate DTD(Operation1)+DTD(Operation2)+DTD(Operation) End of Line Rate 首次合格率－ FTT First Time Through 衡量指標 —FTT 定義 Definition 1 ? .FTT是為在一完整制程生產(chǎn)中，第一次既符合品質(zhì)要求的產(chǎn)品件數(shù)的百分比率 ? 不含 被報廢 ，返工，重試驗， 線 外修理，返回件數(shù) First Time Through is the percentage of units that plete a process and quality guidelines the first time without being scrapped, return, retested, repaired, or returned 衡量指標 —FTT 定義 Definition 2 ? .FTT是衡量生產(chǎn)制程的品質(zhì) ? it is a measure of the quality of the manufacturing process ? .可應用 FPS程序工具改善 FTT (防誤措施，幕式化工廠，快速轉(zhuǎn)換 ) we can improve our FTT by applying our FPS process and tools (error proofing, visual factory quick changeover). 衡量指標 —FTT ? FTT首次合格率 投入制程總件數(shù) （報廢 +返工 +重試 +線外修理 +退回件數(shù)） ? Units entering process – (Scrap + returns + retests + repaired offline +returns) 投入制程總件數(shù) Units entering process 衡量指標 FTT 利益 Benefits 1 ? .提升制程 /品質(zhì) 不良減少 ，庫存 降低 ,改善 DTD時間 ? Increased process/out quality reduces the need for extra production inventory, improvement DTD time. ? .改善及維護順序通過制程 以 改進 BTS ? improves and maintains sequence throughout the process, improving Build to schedule (BTS). 衡量指標 FTT 利益 Benefits 2 ? .確保接收良品提高品質(zhì)水準與降低浪費產(chǎn)生 並 全面提升 OEE ? Increased quality before the constraint ensures that it only receives ―good parts‖ which promotes a higher quality rate and reduces wasted out at the constraint ,which all improve the OEE ? .以降低索賠（保證）， 報 費，與修理成本改善總成本 ? Total cost is improved through lower warranty, scrap and repair costs 衡量指標 FTT 為什 麼 Why:1 ? 改善 FTT成果將 improvements in First Through will result in: .提升產(chǎn)能 increased capacity .改善產(chǎn)品品質(zhì)對內(nèi)部及外部客戶 Improved product quality to internal and external customers .降低大量生產(chǎn)庫存結(jié)果，改善了 DTD時間 Reduced need for excess production inventory resulting in improved Dock to Dock time 衡量指標 FTT 為什么 Why:2 ? .改善了能力以維護順序通過制程 改善了 BTS improved ability to maintain sequence throughout the process resulting in improved Build Schedule ? .提升品質(zhì) 加入作業(yè)要求改善 OEE increased quality input to constr
