精實生產 簡介 Let’s define Lean Manufacturing精實生產的定義 For our discussion, we will define lean manufacturing as the “ process of identifying and eliminating waste within our operations including manufacturing, engineering and administration.” 對於此次課程討論而言，我們將「精實」定義為：「生產、設計與管理運作當中，『找出』並『消除』浪費的過程。」 Evolution of the Manufacturing System The process of manufacturing and supplying products has evolved from simple craft production to a fast-paced, global-oriented arena.產品的產銷流程已經從手工製造發展到快速、全球導向的競爭中。 Customer demand is the universal driver in change所有改變的驅動力是：客戶需求 Why make the change to Lean Manufacturing?為何要轉變到精實生產？ Lean Manufacturing implementation has been shown to aid companies in the following areas:精實生產已運用在下列範疇中： So, what is Lean Manufacturing?那麼，什麼是精實生產呢？ How should we determine what “waste” is:我們如何定義浪費？ While products made in each factory may be different, the typical wastes found in factories are similar:雖說產品各有不同，但工廠裡出現的浪費卻是類似的： Waste of Product Defects產品不良的浪費 When defects occur at one station, operators at subsequent stations waste time waiting, thereby adding cost to the product and adding production lead time.當某工序出現瑕疵時，下工序的人就必須「花時間」等待，因此增加產品成本與等待時間。 Furthermore, rework may be required or the defective products are scrapped.不只如此，可能還要返工或報廢該產品。 If a defect occurs in assembly, additional labor is required to disassemble and additional parts are required to reassemble.如果成型出現一個不良，額外的動作就會被用作來拆裝；也需要另一個新物件來重新組裝。 Waste of Conveyance運送的浪費 For Example範例： Raw material being stored away from the place of use.原物料儲存處遠離現場 Result結果： We must inform tracking personnel where to pick up material我們必須告知專門運送人員去提領物料 We will need additional storage location other than point of use我們需要在現場之外準備儲存區域 We need additional material movement personnel and equipment我們需要額外運送物料的人員與設備 Waste of Motion動作的浪費 Whatever time not spent in adding value to the product should be eliminated as much as possible.與增加產品價值無關的時間，都應該盡可能地消除。 Movement does not necessarily indicate value-added work.「移動」不必然表示它是個「增加價值」的工作。 Wa
