Abstract

In this paper, we propose a new architecture for decentralized control of discrete event systems, whose basic principle is as follows: for every event which is controllable by several supervisors, each of the latter takes an enabling/disabling decision only when it is sure that this is the right decision which can be applied to the plant. Otherwise, the supervisor transmits its local information to the fusion system which will thus be involved in the enabling/disabling decision-making. We compare our approach with the previous decentralized approaches.
