JIT production planning approach with fuzzy due date for OKP manufacturing systems

In general practice, most customers use a fuzzy due date rather than exact date when operating their one-of-a-kind product (OKP) manufacturing systems. They usually have different degrees of satisfaction with the due date. In order to clearly describe the practical problems, two kinds of models with different types of fuzzy due dates for OKP manufacturing systems are built to control production by the just-in-time (JIT) philosophy. In addition, we have developed an algorithm for JIT production planning with a fuzzy due date. The proposed method extends the traditional production planning approaches that have a precise nature to those with a case imprecise nature. The computational results have shown that the algorithm has the potential to be applied to practical OKP manufacturing systems.
