Abstract

This study explores a new application of Case-Based Reasoning (CBR) in the due-date assignment problem of the wafer fabrication factory. Owing to the complexity of the wafer fabrication, the manufacturing processes of the wafer are very complicated and time-consuming. Thus, the due-date assignment of each order presents a challenging problem to the production planning and scheduling people. Since the product of each order is closely related to the products manufactured before, the CBR approach provides a good tool for us to apply it to the due-date assignment problem. The CBR system could potentially replace the human decision in the estimation of the due-date. Therefore, a CBR system is developed in this study using the similarity coefficient of each order with previous orders. The experimental results show that the proposed approach is very effective and comparable with a neural network approach.
