Special Issue Information

Dear Colleagues,

Models play a fundamental role in science and engineering, as abstraction and reduction allow the intended rigor and preciseness. Their readability also allows and facilitates their use as the basis for communication between users and engineers.

Petri nets are very suitable to support this interaction, as they can graphically specify sequence, concurrency, conflicts, and synchronizations. Petri nets provide a mathematically rigorous language for the construction of models with precise semantics, which can then be simulated and verified with modern computing tools.

This has made Petri nets a well-known formalism widely used in different application areas. In order to tune the models to specific application areas, several extensions of Petri nets have been defined, originating from different classes of Petri nets (e.g., synchronized, colored, timed, object-oriented, continuous).

The main aim of this Special Issue is to seek high-quality submissions addressing original research on Petri net modeling, as well as those on topics relevant to distributed and concurrent systems.

The topics of interest include but are not limited to:

  • System design and model-driven development using nets;
  • Structuring and composability in Petri nets modeling;
  • Verification and model checking using nets;
  • Tools for modeling and verification;
  • Tools for rapid prototyping using nets;
  • Code generation from Petri nets models;
  • Relationships between Petri nets and other approaches;
  • Applications in different areas, such as healthcare systems, industrial automation, home and building automation, smart grids, manufacturing systems, real-time systems, chemistry processes, and social sciences;
  • Applications to cyberphysical systems, Internet of Things, embedded systems, controller network, automotive networks, and wireless sensor networks, among others.

Papers reporting new and unpublished advances on any aspect of these topics are welcomed.

Simulation is a powerful process for perfectly planning and dimensioning web systems. However, a successful analysis using a simulation model usually requires variable load intensities. Furthermore, as the client’s behavior is subject to frequent changes in modern web systems, such models need to be adapted as well. Based on web systems observation, we come across the need for tools that allow flexible definitions of web systems load profiles. We propose Timed Colored Petri Nets (TCPN) event generators for web environments that could be used to drive simulations for performance evaluation. The article proposes the systematization of the generators for future development. The theoretical part focuses on a classification with a division into deterministic/stochastic and untimed/timed generators. Next, in this study, we investigate representative models of generators from different classes based on the formalism of TCPN. We perform model design and simulation processes using CPN Tools software. Finally, we present a case study involving workload analysis of a web system that processes requests from the designed generator. Full article
