Abstract :
In this paper we present an approach to solve the problem of diagnosability of bounded Petri net systems. In particular, we first give necessary and sufficient conditions for diagnosability. Then, we present a method to test diagnosability that is based on the analysis of two graphs that depend on the structure of the net, including the faults model, and the initial marking. The first graph is called basis reachability diagnoser, the second one is called modified basis reachability graph.
