This paper proposes a distributed deadlock avoidance policy for flexible manufacturing systems. The whole digraph model is decomposed into subsystems, which could be controlled locally and independently by a suitable deadlock avoidance policy. The flexibility of the deadlock avoidance policy is demonstrated and the complexity analysis is given
In this paper, we present a filtered beam search method to solve deadlock-free scheduling problems in FMSs, which are proven to be NP-hard. Some methods in literatures have been proposed to solve those problems, however, they are very time-consuming and not applicable in large scale systems. The algorithm presented in this paper is based on a fast and approximate heuristic method in searching decision...
