Priority nets for scheduling flexible manufacturing systems

Abstract On-line scheduling and control of flexible manufacturing systems is highly complex due to a number of variables and feasible alternatives. In this context, priority nets are developed for flexible and realistic modeling and simulation of flexible manufacturing systems (FMSs). A dynamic scheduling algorithm is described that employs priority net aided simulation to determine the operating policies under varying conditions of FMS operation. The efficacy of the algorithm is demonstrated with a case study.
