Coverability tree
WebApr 10, 2024 · A basis coverability graph (BCG) is constructed to address the CSO verification of a DES modelled with unbounded Petri nets (UPNs); such a system cannot be modelled with a finite state automaton. A condition in [ 6] is extended, i.e., some unobservable transitions can be detected in a partially observed DES. WebMar 1, 2024 · Coverability tree (co-tree) is a very important tool for the analysis of Petri net models. In coverability analysis, we determine the states that are reachable from a given initial state, assuming that all the transitions always fire if enabled.
