Deadlock problems in flexible manufacturing systems (FMS) have received more and more attention in the last two decades. Petri nets are one of the more promising mathematical tools for tackling deadlocks in various resource allocation systems. In a system modeled with Petri nets, siphons are tied to the occurrence of deadlock states as a structural object. The book systematically introduces the novel theory of siphons, traps, and elementary siphons of Petri nets as well as the deadlock control strategies for FMS developed from it. Deadlockprevention methods are examined comparatively. The many FMS examples presented to demonstrate the concepts and results of this book range from the simple to the complex. Importantly, to inspire and motive the reader’s interest in further research, a number of interesting and open problems in this area are proposed at the end of each chapter. Gives the reader new methods for avoiding bottlenecks and interruptions in the manufacturing process, elevating efficiency and reducing costs Contains many real-world examples of flexible manufacturingsystems from which readers may draw parallels with their own systems INDICE: Introduction.- Petri Nets.- Elementary Siphons of Petri Nets.- Monitor Implementation of GMEC.- Deadlock Control Based on Elementary Siphons.- Optimal Liveness-enforcing Supervisors.- Comparison of Deadlock Prevention Policies.- Conclusions and Future Research.
