In a manufacturing system, completion time of an order is affected by many factors related to order characteristics and system status and is very difficult to predict accurately. Also, the level of influence of each factor on completion time of an order may depend on the production system characteristics, such as the releasing and dispatching rule used. Discussed in this paper are a method to identify factors that have significant effects on completion times of orders under various combinations of scheduling rules through computer simulation and statistics analyzes, then develop due date assignment rules. The first step of the research is selecting releasing and dispatching rules that had more cited times in related research of wafer fabrication. Second, for each combination of scheduling rules combine simulation and statistics analyze to find out the effective predicted factors of completion times of orders. Third, for each combination of scheduling rules establish efficient due date assignment rules according to the effective factors through regression model to predict the due date of orders accurately.
