A hybrid intelligent approach is proposed which can be used to estimate the output of each product type in a semiconductor fabrication plant. This is a critical task for plant operation. First, the hybrid fuzzy-c-means (FCM) and fuzzy-back-propagation-neural-network (FBPN) approach is applied to estimate the output time for every job in the plant. Subsequently, the fuzzy output projection function (FOPF) is proposed to project the outputs into each future time period. To evaluate the advantages and/or disadvantages of the hybrid intelligent approach, a simulated semiconductor plant model is also used in this study to generate test data. From the experimental results, the output projection accuracy by the hybrid intelligent approach was significantly better than that of some existing approaches. |
