Ensuring nonblockingness remains challenging for automated manufacturing systems (AMS) owing to their discrete event dynamics. Both scalability and maximal permissiveness are essential for the synthesis and implementation of their centralized supervisors. Inspired by the divide and conquer philosophy, this work proposes a partition methodology and distributed control technique for large scale AMS...
In the framework of automated manufacturing systems (AMS), Petri nets are widely used to model, analyze, and control them. Resolving deadlocks is of paramount significance because their emergence reduces the system throughput to zero. Supervisory control technique is the most widely adopted method to resolve them. A control policy can be converted into satisfying a set of inequalities, each of which...
The mixed integer programming (MIP)-based deadlock detection method plays an important role in the development of deadlock prevention policies for flexible manufacturing systems (FMS). In this paper, an optimal deadlock prevention policy is proposed for a class of Petri nets called Systems of Simple Sequential Processes with Resources (S3PR) without any ξ-resource. A ξ-resource is a one-unit resource...
