Given the PN model (PNM) of an FMS prone to deadlock, the goal is to synthesize a live controlled PNM. Its use for FMS control guarantees its deadlock-free operation and high performance in terms of resource utilization and system throughput. The proposed method is an iterative approach. At each iteration, a first-met bad marking is singled out from the reachability graph of a given PNM. The objective is to prevent this marking from being reached via a place in variant of the PN. A well-established invariant-based control method is used to derive a control place. This process is carried out until the net model becomes live. The proposed method is generally applicable, easy to use, effective, and straightforward although its off-line computation is of exponential complexity. Two FMS are used to show its effectiveness and applicability.eninfo:eu-repo/semantics/closedAccessdeadlockdeadlock preventionflexible manufacturing systems (FMS)Petri net (PN)reachability analysisArticle37336237110.1109/TSMCA.2007.8934842-s2.0-34247199855N/AWOS:000246034500008Q2
