Titre / Title: Symbolic Graph for Petri nets
Abstract : In this paper we consider programs with one parameter, the number of processes, represented by Petri nets. A marked Petri net models a program with a fixed number of processes, i.e., an instantiated program. We give an algorithm to build a symbolic graph that represents the reachability graphs of a Petri net with an infinite number of initial markings. There is an initial marking for each value of the parameter. We introduce symbolic markings that define sets of markings of instantiated programs. We prove that the symbolic graph represents exactly the reachable markings of all the instantiated programs. Each possible execution of an instantiated program is represented in the symbolic graph. We show how to verify properties on the symbolic graph.
