Mobile Synchronizing Petri Nets: A Choreographic Approach for Coordination in Ubiquitous Systems
The term Ubiquitous Computing was coined by Mark Weiser almost two decades ago. Despite all the time that has passed since Weiser's vision, ubiquitous computing still has a l...

A Petri-Net Based Reflective Framework for the Evolution of Dynamic Systems
Nowadays, software evolution is a very hot topic. Many applications need to be updated or extended with new characteristics during their lifecycle. Software evolution is character...

Petri Nets and Matrix Graph Grammars: Reachability
This paper contributes in two directions. First, several concepts of our matrix approach to graph transformation [1,2] such as coherence and minimal initial digraph are applied to ...

Matching observed behavior and modeled behavior: An approach based on Petri nets and integer programming
Inspired by the way SAP R/3 and other transactional information systems log events, we focus on the problem to decide whether a process model and a frequency profile "fit"...

Free Choice Petri Nets without frozen tokens and Bipolar Synchronization Systems
Bipolar synchronization systems (BP-systems) constitute a class of coloured Petri nets, well suited for modelling the control flow of discrete dynamical systems. Every BP-system ha...

Timed Petri nets and timed automata: On the discriminating power of zeno sequences
Timed Petri nets and timed automata are two standard models for the analysis of real-time systems. In this paper, we prove that they are incomparable for the timed language equival...

Integration of the Association Ends within UML State Diagrams
: UML currently still lacks a rigorously defined semantics for its models, which makes formally analyzing a model and verifying its properties extremely difficult. To remedy that, ...

Analyzing Reachability for Some Petri Nets With Fast Growing Markings
Using linear algebraic techniques, we analyse the computational complexity of testing reachability in Petri nets for which markings can grow very fast. This leads to two subclasse...

Analyzing interacting WS-BPEL processes using flexible model generation
We address the problem of analyzing the interaction between WS-BPEL processes. We present a technology chain that starts out with a WS-BPEL process and translates it into a Petri ...
