Abstract: Predicting job completion time is an important but difficult task to a semiconductor fabrication plant. To further enhance its effectiveness, an evolving hybrid neural approach is proposed in this study. To evaluate the effectiveness of the proposed approach, Production Simulation (PS) is also employed to generate test data. According to experimental results, the predicting accuracy of the evolving hybrid neural approach is significantly better than those of many existing approaches. In addition, to improve the practicability of the evolving hybrid neural approach, several issues in practical applications are addressed and discussed. Though the proposed evolving hybrid neural approach seems to be theoretically complicated, its ease of implementation on the production planning and control for a semiconductor plant is demonstrated in this study.
