A systematic procedure is proposed in this study for output time forecast achievability evaluation in a wafer fab (fabrication plant), which is a critical task to the wafer fab. At first, a BPN is used to predict the output time of a wafer lot. Subsequently, a set of fuzzy inference rules (FIRs) is established to evaluate the achievability of an output time forecast, which is defined as the possibility that the fabrication on the wafer lot can be finished in time before the output time forecast. Managerially, achievability is as important as the other two performance measures in this field: precision and efficiency. However, the evaluation of achievability has not been investigated in traditional studies.
