In a companion paper [BPV06], we investigated the expressiveness of Time Petri Nets extended with Priorities and showed that it is very close to that Timed Automata, in terms of weak timed bisimilarity. As a continuation of this work we investigate here the applicability of the available state space abstractions for Bounded Time Petri Nets to Bounded(More)
The paper is organized as follows. Section 2 reviews the terminology of time Petri nets and the definitions of their state spaces. The classical "state classes" construction, preserving markings and LTL properties, is explained in section 3, and its properties discussed. Section 4 explains the richer "strong state classes" abstraction, that allows in(More)
Systems’ requirements are usually written in a natural language since it generally means a greater understanding among the various stakeholders. However, using an informal language potentially gives rise to interpretation problems, which are to be resolved prior to using (automated) verification techniques. This article tackles an important issue pertaining(More)
Diagnosability is a procedure whose goal is to determine whether any failure – or a class of failures – can be determined in finite time after its occurrence. Earlier works on diagnosability of discrete event systems (DES) establish some intermediary models from the analyzed model and then call some procedures to check diagnosablity based on these models,(More)
Finding an infinite sequence of transitions (a run) going through some special states (called accepting) is of importance for fields like formal verification. Whereas finding such a sequence as been extensively studied, the problem of maintaining this sequence upon changes in the model or the specification has received less attention. In this work, we(More)
