Petri nets are less expressive than state-extended PA
We show that the class of Petri nets is less expressive with respect to bisimulation equivalence than the class of PA processes extended with a finite state control unit. Key word...

Extension of Petri Nets for Representing and Reasoning with Tasks with Imprecise Durations
This paper presents an extension of Petri net framework with imprecise temporal properties. We use possibility theory to represent imprecise time by time-stamping tokens and assig...

Modeling and Supervisory Control of Railway Networks Using Petri Nets
In this paper we deal with the problem of modeling railway networks with Petri nets so as to apply the theory of supervisory control for discrete event systems to automatically de...

Analysis of Approximate Petri Nets by Means of Occurrence Graphs
Abstract. Approximate Petri nets (AP-nets) can be used for the knowledge representation and approximate reasoning. The AP-net model is defined on the basis of the rough set approa...

Interpreted Nets
The nets considered here are an extension of Petri nets in two aspects. In the semantical aspect, there is no one firing rule common to all transitions, but every transition is tr...

An Axiomatization of the Token Game Based on Petri Algebras
The firing rule of Petri nets relies on a residuation operation for the commutative monoid of natural numbers. We identify a class of residuated commutative monoids, called Petri ...

A Structure Causality Relation for Liveness Characterisation in Petri Nets
: Characterising liveness using a structure based approach is a key issue in theory of Petri nets. In this paper, we introduce a structure causality relation from which a topologic...

Associative Omega-product of Processes
The notion of an associative omega-product is applied to processes. Processes are one of the ways to represent behavior of Petri nets. They have been studied for some years as an ...
