發電機操作訓練專家系統開發之研究
Development of an Expert System for Generator Operation Training
摘要
由於半導體產業大多數是以24小時連續的生產方式，來提高機器的使用率，若是產生停電等意外事件，則需要一段不少的維修及熱機的時間，不論在良率或是生產力方面都會受到極大的影響，所以重要的機台幾乎都會連結到自動發電系統來持續提供電力，使機台繼續維持生產力，將損失減到最小，所以幾乎每個工廠都備有發電機以備不時之需，但是發電機台的操作極為複雜，造成員工沒有辦法在第一時間做出最正確的反應 本研究以W工廠為實際的例子，設計一套兼具教育訓練與緊急應變的專家系統，一方面藉著專家系統來有效率的訓練新進的人員以及對老手做重複的訓練，另一方面設計一個搜尋系統，來提供輪值員工在發生緊急事件的時候，可以藉由這套系統來獲得一個較為正確的解決辦法，利用這套系統來縮短員工對於緊急事件的反應時間且提高正確性。 本實驗以二十二位沒有發電機經驗的清華大學工業工程學生做為受試者，將受試者隨機分成兩組，一組接受傳統的訓練方式，另一組使用本研究所發展的訓練系統，績效衡量指標為受試者完成訓練程序之後，接受測試之正確性的分數，結果顯示本研究所發展之系統在教學的成效上有顯著的幫助，但是在教學時間的縮短上，並沒有顯著的幫助，此外系統可模擬發電機實際的操作介面，有效的幫助員工在不常接觸機器的情況下，模擬機器的操作情形，增加操作的熟練度，來幫助員工在突發狀況發生時，更正確、更迅速的做出正確的反應。經由結果的討論，提出本研究的貢獻、限制及未來的發展方向，有待未來增加應用的範圍與層面。

The expensive facilities of semiconductor run for 24 hour a day in order to keep high utility rate. If any accidents such as power failure happen, it takes lots of time to set up and fix the facilities for reoperation, and results in significant negative effects on yield and production. In most companies, the important machines are protected by generators. Generators keep machines operated continually and reduce loss when power fails. However, the control of generator system is complex, and thus only experts could control generators well. Most staffs cannot make the best decision immediately for lacking experiences or practice. In this research, an expert system was developed including training function and emergency searching function in W factory. Then, an experiment was conducted to verity the effect of the generator training system. Subjects were 22 students in industrial engineering at NTHU. None of the students had experiences about generators before. These subjects were randomly assigned to one of the training conditions. One group used generator training system for training, and the other group received conventional training. The accuracy of test after training and training time were used to evaluate subject’s performance. From the results of the experiment, one could see that there was no significant different between generator training system and conventional training on training time, but generator training system had better performance in accuracy of test. The main, contributions and limitation of this research were discussed. For the future study, the similar design concept can be applied to other complex machines in the factory to improve performance on emergency operation.
