限制驅導式在製罐產業生產管理之應用研究

本文主要是在探討傳統產能的生產線設計與限制驅導式排程與管理（Drum-Buffer-Rope, DBR)產能的生產線設計之優劣比較，並應用且藉此改善A公司之生產效率。良好的生產製造系統能夠降低生產週期時間與提高達交率。為了達成這些目標，製造系統必須應付各種變異事件與隨機波動的影響，同時要使生產成本極小化。鑑於此，傳統生產上追求產能平衡並在各製程前面設置大量在製品，來保護整個生產線，此導致較長的生產週期時間，容易傷害交期的可靠度並使成本提高。而由限制理論(Theory of constraints, TOC)所延伸出來的DBR 生產，是藉由派工的調整與瓶頸的控制，讓系統的產出與瓶頸同步，達到生產線流量(Flow)平衡，本研究方法將製罐現場生產線狀況，以DBR方式來規劃設計執行，再以實際工廠生產線運作之方式收集資料並計算出實際生產運作的結果, 並以統計檢定，其顯示應用以DBR的生產線方式比傳統的生產線方式有更好的成果。

The purpose of this paper is to compare the benefits of two ways of Production’s line design. One is traditional capacity design, and the other is DBR（Drum-Buffer-Rope, DBR）protective capacity design, and also based on the result to improve the production efficency of case A company . A good manufacturing system is enable to reduce production cycle time and raises the reliability of due day. In order to reach the objectives, manufacturing system must overcome the effects of various variable events, random fluctuation on production line, and minimum of the production cost as well. In view of the foregoing, traditional production system pursues capacity balance and places work-in-process (WIP) inventory in front of every machines to protect overall line, which will lead to production cycle time raise and lower the reliability of due day. Meanwhile, the DBR production system pursues flow balance and work adjusts. In general, DBR investment will greater than traditional capacity balance, but it will show good results in lowering WIP, cycle time, and due day. As to the results, how many the benefits will be? In order to answer the benefits, this research builds a real production line (DBR system) in the can-making plant to compare and analyze the results of both production line design concepts. It shows that the DBR system gets better results than traditional system.
