چکیده

In this paper, we show that the evolution equations for timed free choice Petri net can be used to prove logical properties of the underlying un-timed net. For example, this approach leads to new methods and algorithms to check liveness and several other basic properties, such as absence or presence of deadlocks. The main tools for proving these properties are graph theory and idempotent algebras. Vivacitt des rrseaux choix libres approche alggbrique RRsumm : Dans cet article, nous montrons que les quations d''volution pour un rrseau de Petri choix libres temporiss permettent d''tablir des propriitts logiques du rrseau non temporiss sous-jacent. Par exemple, cette approche ammne de nouvelles mmthodes et de nouveaux algorithmes pour tester la vivacitt du rrseau et d'autres propriitts comme la prrsence ou l'absence de blocages dans le rrseau. Les principaux outils utilisss sont la thhorie des graphes et les alggbres idempotentes.

Free-choice Petri Nets an Algebraic Approach

In this paper, we give evolution equations for free choice Petri net which generalize the max; +]-algebraic setting already known for event graphs. These evolution equations can be seen as a coupling of two linear systems, a (min; +)-linear system, and a quasi (+;)-linear one. This leads to new methods and algorithms to: In the untimed case: check liveness and several other basic logical proper...

Complexity Results for 1-safe Nets

We study the complexity of several standard problems for 1-safe Petri nets and some of its subclasses. We prove that reachability, liveness, and deadlock are all PSPACE-complete for 1-safe nets. We also prove that deadlock is NP-complete for free-choice nets and for 1-safe free-choice nets. Finally, we prove that for arbitrary Petri nets, deadlock is equivalent to reachability and liveness.

On Compositionality of Boundedness and Liveness for Nested Petri Nets

Nested Petri nets (NP-nets) are Petri nets with net tokens. The liveness and boundedness problems are undecidable for two-level NP-nets [10]. Boundedness is EXPSPACE and liveness is EXPSPACE or worse for plain Petri nets [4]. However, for some restricted classes, e.g. for plain free-choice Petri nets, problems become more amenable to analysis. There is the polynomial time algorithm to check if ...

On liveness and boundedness of asymmetric choice nets

This paper concerns two important techniques, characterization and property-preserving transformation, for verifying some basic properties of asymmetric choice Petri nets (AC nets). In the literature, a majority of the characterizations are for ordinary free choice nets. This paper presents many extended (from free choice nets) and new characterizations for four properties: liveness with respec...

On a Free-Choice Equivalent of a Petri Net

A Petri net (PN) 2, 3] is said to be live if it is possible to re any transition from every reachable marking, although not necessarily immediately. In this paper we consider the issue of enforcing liveness in non-live PNs via supervisory control. Using a construction procedure , similar to that in reference 1], that converts an arbitrary PN into an equivalent member of a family of PNs called F...

An Efficient Polynomial-Time Algorithm to Decide Liveness and Boundedness of Free-Choice Nets

In 3] J. Esparza presented an interesting characterization of structurally live and structurally bounded Free-Choice Nets (LBFC-Nets). Exploiting this characterization in combination with new results and reened algorithms the authors formulate an O(jPjjTjjFj) algorithm deciding whether a Free-Choice Net is a LBFC-Net or not. Furthermore the algorithm contains a simple and eecient test to ensure...
