Abstract

This paper addresses the optimization of a sorting system encountered in the semiconductor industry. Thesystem consists of parallel sorting machines and a material handler to transport materials to, from andbetween machines. The problem is decomposed into multiple subproblems. For each of these subproblemsheuristic methods are proposed. A discrete-event simulation is used to study the performance of thesystem using these heuristics. Application on two real-world cases shows that this heuristic approach cansignificantly decrease the makespan and cost, yielding practically feasible schedules.
