Goal programming methods for implementation of just-in-time production

Abstract Lot size and setup time reduction for the just-in-time (JIT) system have been studied extensively using different EOQ model approaches. However, the decision making process for lot size and setup time reduction under JIT usually involves mixed model production and multiple conflicting objectives. Thus, goal programming (GP) is an ideal tool for this decision problem. This paper deals with the problem of fabricating different models of the same general product on one production line. It also discusses the superior aspects of GP over conventional EOQ approaches when solving lot size and setup time problems for JIT. A GP model is presented and the implementation results of an illustrative problem are discussed.
