摘要:	由於現今產業競爭加劇、品質要求嚴苛、訂單少量多樣且變動劇烈、交貨前置時間壓縮，使得製造業持續面臨經營的艱困挑戰。而無論是傳統或者電子產業的製造部門，無不以提昇產品品質、準時交貨，同時保持最佳生產效率、維持正常庫存水準作為營運目標，才能保持企業競爭力。本研究探討導入「製造執行系統」（MES, Manufacturing Execution System）取代原有系統的過程分析，並根據文獻探討予以彙整資訊，更進一步整理更換製造系統之原因、過程，以及系統導入效益，檢視是否符合個案公司預期達到提升生產效率、落實產品生產溯源、降低庫存水準的目標。本研究採用「質性研究方法」中的「個案研究法」來進行探討，深入研究個案的現況、發展過程與系統導入所遭遇的問題，與系統上線後是否達成專案預期效益。經由研究發現，藉著系統設計的嚴謹與作業流程重整，可有效杜絕人為作業疏失，有助於企業加強生產流程控管、提高資訊正確性、改善良率與降低營運成本。 ;Manufacturing firms are all facing increasingly more difficult challenges to sustain competitiveness. The challenges include increased industry competition, more stringent quality requirements, greater variety in smaller quantities of customer orders, larger fluctuations, and compressed delivery time. No matter in the electronic industries or traditional industries, the manufacturing units all have to continuously improve product quality, delivery time, production efficiency, inventory management to ensure the competitiveness of the company. This study analyzes the replacement of MES (Manufacturing Execution System) from the original one. Based on the framework from a literature review, the analysis provides the reasons for the replacement of manufacturing systems, and the impact and effectiveness of such a replacement. The case study also shows whether the company has achieved the objectives of implementing the new system such as improvement in production efficiency, enhanced product traceability, and reduction in inventory levels. This case study uses qualitative approach to explore the research issues in-depth from the original situation, the development processes, to the implementation stage. The study also evaluates the achievement of expected efficiency. This study shows that by flowing the exact design of the system and reforming work processes, implementing the MES can effectively reduce the human errors, improve process control, information accuracy, and production yield rate, and then decrease the operation costs. The results of the case study provide the key factors and issues that may cause the delay of MES implementation, offering implications that may help other companies in successfully introducing MES.
