Abstract :
This paper deals with fault detection of manufacturing systems modeled by Petri nets. We show that the theoretical results obtained for continuous Petri nets allow us to treat with systems that are intractable using the theory developed for discrete Petri nets. In particular systems in which the unobservable part contains cycles can be studied. On the other hand, only three diagnosis states can be defined making impossible the splitting of the uncertain state into two different states, to obtain different degrees alarm for the uncertainty.
