摘要

今日，全球企業的經營環境快速變化，產業間彼此的競爭非常激烈，除了不斷地加強產品研發創新的能力以及行銷策略的手法，更必須提高製程系統的能力。一個能提供高品質、低成本，以及交期準確的製程系統，往往會是企業競爭力的基本根源。
在製程系統中，現場排程往往扮演著關鍵性的角色。一個不良的排程系統將會影響產品的生產效率，造成在製品的堆積，和訂單交期的延誤。因此，本研究透過限制驅導式現場排程(Drum-Buffer-Rope, DBR)的手法，與個案工廠現況排程方法的實例演練做比較，尋求一個改善生產效率與控制排程的最佳手法。
而由本研究的實例演練中，可以從其結果得知以DBR的現場排程方式相較於個案工廠現況排程方法，可以更明白地指出製程系統的瓶頸所在，並且根據瓶頸給予適當的緩衝區間。以執行一個妥善的生產排程機制，來掌握現場的生產狀況，與交期預測和控制，以確保產品的如期產出，進而提升顧客滿意度，獲取更大量的訂單。

Nowadays, the environment of global business is changing rapidly. Due to the severe competition, companies not only have to strengthen their product innovation ability and marketing strategy, but also need to improve the manufacturing management. An effective production scheduling system will improve the quality, lower the cost and assure the delivery time. Hence, production scheduling is one of the fundamental factors in commercial competition.
In manufacturing management, on-site scheduling plays a crucial role. An inefficient scheduling system can affect the production efficiency, sequence and eventually cause excess inventory or shipping delay. This research sought solutions to improve production efficiency and scheduling by comparing the Drum-Buffer-Rope (DBR) methodology with the case study practiced in a factory.
After the field practical experiment, the bottleneck of production could be easily identified by using on-site planning of DBR, in contrast to the existing scheduling method in the factory. Therefore, buffer zones could be properly arranged according to the bottleneck. As a result, by operating an efficient manufacture schedule to control the production line, predicate the lead-time and avoid delay will consequently increase the customer satisfaction and bring more orders to the company.
