Petri nets are excellent networks which have great characteristics of combining a welldefined mathematical theory with a graphical representation of the dynamic behavior of systems. The theoretical aspect of Petri nets allows precise modeling and analysis of system behavior, at the same time, the graphical representation of Petri nets enable visualization of state changes of the modeled system ...

A polynomial algorithm was given by the authors and Bernar-dinello for synthesizing pure weighted Petri nets from nite labeled transition systems. The limitation to pure nets, serious in practice e.g. for modelling waiting loops in communication protocols, may be removed by a minor adaptation of the algorithm, working for general Petri nets red sequentially. The rule of sequential ring reduces ...

This paper introduces PeCAn, a tool supporting compositional verification of Petri nets. Beyond classical features (such as onthe-fly analysis and synchronisation between multiple Petri nets), PeCAn generates Symbolic Observation Graphs (SOG), and uses their composition to support modular abstractions of multiple Petri nets for more efficient verification. Furthermore, PeCAn implements an incre...

Analytical modeling is a crucial part in the analysis and design of computer systems. Stochastic Petri Nets represent a powerful tool, widely used for dependability, performance and performability modeling. Many structural and stochastic extensions have been proposed so as to increase their modeling power. In this paper we review the main structural and stochastic extensions of Petri nets, by p...

Petri Nets are tools for the analysis and design of concurrent systems. There is a formal theory, which supports Petri Nets. We propose Petri Nets with Clocks which has a high expressive power in the concurrent and asynchronous process modeling and gives the possibility to model real time systems. The Petri Nets with Clocks are useful to model systems with temporal requirements via specificatio...

Within MDA models are usually created in the UML. However, one may prefer to use different notations such as Petri-nets, for example, for modelling concurrency and synchronization properties of systems. This paper claims that techniques that are adopted within the context of MDA can also be beneficial in modelling systems by using notations other than the UML. Petri-Nets are widely used for mod...

When designing complex systems, mechanisms for structuring, composing, and reusing system components are crucial. Today, there are many approaches for equipping Petri nets with such mechanisms. In the context of defining a standard interchange format for Petri nets, modular PNML was defined as a mechanism for modules in Petri nets that is independent from a particular version of Petri nets and ...
