Most traditional research in this area used only time-based rules and performance criteria. Ho wever, in most managerial problems, cost was a more global and homogeneous cri terion than time-based criteria such as flow-time and lateness. Therefore, min imizing total cost is a more appropriate objective.This article investigates t he scheduling problem of FMSs by using a simulation model of an FMS. Specifica lly, relative performance of scheduling rules for machines and automatedguided vehicles (AGVs) are analyzed against the total cost criterion. Furthermore, o ne new composite rules is proposed, using job due date, processing time, curre nt shop time, inventory holding cost, and tardiness cost information. The new rule is compared with five other well-known rules that are basically time-orie nted and cost-based. Results show that total cost dependent scheduling rules o utperform total cost independent rules.
