排程問題演變至今,已有眾多的專家學者以及業界先進,研究出許多的解決方法,然而在實務應用上,該選擇哪一種方法來解決排程問題,仍須考量產業特性、產品特性、加工類型,以及環境設備等限制因素;除此之外,所選定之方法或模式,亦須配合這些限制條件,來略做調整或改善,以求得最佳解。 本研究以晶片電阻之印刷製程為例,採用基因演算法(Genetic Algorithm),並針對晶片電阻印刷製程之特性與限制條件,來進行流線型等效平行機台之排程,以總延遲時間最小化為目標,研究結果顯示,採用基因演算法來進行流線型等效平行機台之排程,比案例公司現行之排程,有更佳的績效與結果。
Production scheduling problem is an NP-hard problem that has been discussed by many researchers. Therefore, how to raise the scheduling quality is the key issue on real world case. In practical application, Production scheduling problems need to consider many factors related to the characteristics of product, equipments and processes. This research applies the genetic algorithm to the scheduling problems of the chip resistor industry and focuses on the printing process especially. The objective is the minimization of the sum of the tardiness. According to the intensive experimental results, the genetic algorithm is more effective and efficiency than the traditional scheduling method. It shows this algorithm is worth considered for practical application in real world problems.
