For the successful realization of complex systems of interacting and reactive software and hardware components the use of a precise language at different stages of the development process is of crucial importance. Petri nets are becoming increasingly popular in this area, as they provide a uniform language supporting the tasks of modeling, simulation, validation, and verification. Their popularity is due to the fact that Petri nets capture fundamental aspects of causality, concurrency and choice in a natural and mathematically precise way without compromising readability.

The workshop PNSE'26 (Petri nets and Software Engineering) will take place as a satellite event of Petri Nets 2026.

The use of Petri nets (P/T-nets, colored Petri nets and extensions) in software engineering, covering modeling, validation, and verification, will be presented as well as their application and tools supporting the disciplines mentioned above.

This year we will put an emphasize on the impact of software engineering in general and its model based development on Petri nets by their concepts, methods, techniques and tools. Therefore we especially invite contributions that work on subjects that could(!) be relevant for Petri nets, their applications or their tools. Results on other formalisms or semi-formal techniques, their concepts, methods, tools and experiences (successful or not successful) are highly welcome.

As model based development has proven to be very successful, we want to discuss ideas, applications, concepts, foundations and recent results from the area of modeling during the workshop. Communication is based on models, therefore, the transformation from domain models to software models and back are major tasks that we want to discuss during the workshop from several perspectives. Last but not least, in the context of any organizational institution, the roles of modeling and how to use concepts, methods or tools for modeling may be addressed

The idea is to inspire the Petri nets community with new ideas, insights, relevant concepts, etc. In case that you still have doubts if your contribution will fit: Just contact the PC-Chairs!
