WebCoverability trees contain a wealth of information about the system at hand, and allow to answer various coverability and boundedness questions allowing us to derive a new … Webof coverability languages. Then in sections4and5, we show that the coverability and termination problems are EXPSPACE-complete. In section6, we conclude and give some perspectives to this work. All missing proofs can be found in the appendix. 2 Recursive Petri Nets 2.1 Presentation An RPN has a structure akin to a ‘directed rooted tree’ of ...

Weba) Derive the coverability tree of PN1. b) Find a Petri net PN2 such that: 1. the coverability tree of PN2 is the same as that of PN1; 2. in PN2, the marking M = (1, 1, 0, 0) is not reachable from the initial marking M 0 = (1, 0, 1, 0). WebJan 1, 2005 · This contributions provides an introduction to the theory of place/transition Petri nets. Topics include the sequential and the concurrent behavior of place/ transition Petri nets, marking graphs and coverability trees, and some analysis techniques that are based on the structure of place/transition Petri nets.
