Abstract

Based on resource-oriented Petri net models of automated manufacturing systems (AMS), and Wu´s previous work (1999) on a necessary and sufficient condition for deadlock-free operation, this paper proposes a new control policy such that deadlock is completely avoided, starvation and blocking situations are reduced and sometimes eliminated. It attempts to release an appropriate number of jobs into the system and control the order of resource usage based on state information in the net model. The theoretical results for the correctness of this policy are presented. A simple AMS is used to demonstrate its great potential to high utilization and productivity
