Performance evaluation of a flexible machining/assembly system and routing comparisons

This paper discusses the performance evaluation of the flexible machining/assembly systems (FMS/FAS) of a central server type, and gives a comparative consideration of a fixed, dynamic versus an ordered-entry routing rule. First, the steady-state equations are given, and the system throughput is obtained. Next, the system configurations of FMS/FAS are numerically discussed on the basis of system throughput. Finally, the superiority of an ordered-entry routing rule is numerically discussed for development of routing theory.
