In this paper a divide-and-conquer-method for the synthesis of liveness enforcing supervisors (LES) for flexible manufacturing systems (FMS) is proposed. Given the Petri net model (PNM) of an FMS prone to deadlocks, it aims to synthesize a live controlled Petri net system. For complex systems, the use of reachability graph (RG) based deadlock prevention methods is a challenging problem, as the RG...
In this paper, a method is proposed for the computation of liveness enforcing supervisors (LES) from submodels of a Petri net model (PNM) of a flexible manufacturing system (FMS). Given the PNM of an FMS prone to deadlock, it aims to synthesize a live controlled Petri net. The PNM of the system is divided into small connected subnets (submodels). Each connected subnet prone to deadlock is then used...
