A SCHEDULING MODEL OF UNRELIABLE MANUFACTURING SYSTEMS ON RECEDING HORIZON

摘要

An unreliable manufacturing system is examined.The system can produce several types of products.A setup (with setup time or cost or both) is considered when the production is switched from one type of products to another.The decision variables are a sequence of setups and the production plan.After a more straightforward necessary condition and a necessary and sufficient condition for the optimality of the just-in-time (JIT) control policy were presented respectively, based on the hedging point control policy and the idea of JIT (just-in-time), a new real-time receding horizon scheduling algorithm is presented.Numerical results are also presented.
