本研究試圖探討S工廠所面臨的瓶頸,S工廠是一個傳統的IC程式编程(IC燒錄)服務,嚴重依賴手動操作。採用MES系統的概念,結合流程再造的特點。提出了引入資訊技術支援過程的變更建議。預計通過該提案,可以提高生產服務的性能。;The goals of traditional production factories are to effective accomplish the work orders. This relies heavily on experienced personnel. Management is not just about the process itself, but about the people who execute the process, because no matter whether the workflow is complex or not, as long as it involves human operation and judgment, there will be risks. In the era of information technology, even small factories have started to grasp the concept of industry 4.0. The application of information and communication technology can connect the resources, information, goods and people in the field of factory production, so that the transformation of factory to intelligent production can improve the overall production level. The MES system is a production management system for intelligent production. However, the complicated functions of MES system is useless for small factories or the small factories are unable to afford the high development costs of MES system. The real requirement of small factories is to manage key operations with better information, and increase user convenience and flexibility. This study attempts to look into the bottlenecks faced by Factory S, which is a traditional IC Programming (IC burning) Service, heavily relying of manual operations. Concepts of MES systems, combined with features of process reengineering are employed. A proposal to introduce process changes enabled by information technologies is made. It is expected that through the proposal, the performance of the production services can be improved.
