Abstract

We propose an algorithm for the hierarchical decomposition of a large automaton-based discrete-event system. We also provide an estimation of the numerical cost in terms of the size of the system. Our hierarchical decomposition is illustrated with simple examples from dynamical ST-control and supervisory control with uncontrollable events and unsafe states.
