摘要
This study takes a metal product sightseeing factory as an example, and develops a set of intelligent scheduling system; the purposes of this study are decreasing the number of delay orders and minimizing the total production time and so on. This study uses the dispatching rules such as the methods of shortest processing time, first-in/first-out, and early due date as its initial solutions. Then, this study uses random number algorithm (RNA) to optimize the scheduling solutions. Meanwhile, this study also considers the factors of production batch, delivery deadline, set-up time, and the tardiness cost. The decision makers can choose one scheduling performance indicator according to their needs. For instance, the minimum of total completion time, the shortest of total tardiness, the least number of total delay orders, and the smallest of total punishment cost. This study conducts a study of multi-order and multi-product to optimize the production schedule and improve the scheduling performance. The results confirm that the production scheduling system developed by this study has a user interface, and it can get the near optimal solution within 17 minutes or less. Also, the new production route of new products can be added, and the optimal scheduling results would be presented in the form of Gantt chart. In this study, it meets the practical needs and has a good execution performance. © 2019, Chinese Society for Quality. All rights reserved.
