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...
Continuous Petri nets are an approximation of discrete Petri nets introduced to cope with the state explosion problem typical of discrete event systems. In this paper we start the problem of state estimation for timed continuous Petri nets with finite server semantics. Under the assumption that no observation is available, and thus the set of consistent markings only depends on the time elapsed, we...
