PetriNets, by Tagliaferro Mauricio, is an Android app for modeling and simulating Petri nets used to describe concurrent systems. The app lets users construct graphical nets, set initial token markings, and run interactive simulations with manual or automated transition firing to observe behavior. It includes analysis capabilities such as reachability and coverability tree generation plus save/load project support. Designed for university students, engineering professionals, and researchers seeking portable, hands-on practice with formal modeling.

What educational tasks does the app handle?

The app functions as a portable modeling and simulation workspace for Place-Transition Petri nets. Users build diagrams with a graphical editor and add the structural elements they need. Typical elements supported include:

• Places for token storage
• Transitions representing events
• Arcs linking places and transitions

How does the tool support learning formal methods?

The app promotes inquiry through interactive execution and formal analysis. Students can step through transition firings or run automated sequences to observe token flow, and the integrated analysis engine reports structural and behavioral properties such as reachability and boundedness. Generation of reachability and coverability trees helps learners visualize state spaces, which supports hypothesis testing about liveness and deadlocks in small to medium models.

Is the app suitable for beginners, students, or researchers?

The app targets higher-education and professional users, specifically computer science students, engineering professionals, and researchers. Its focus on formal properties means prior coursework or familiarity with Petri nets improves usefulness. The mobile-centric, touch-oriented editor supports quick sketches and experiments, making it convenient for study sessions away from a desktop, though it assumes the user understands core Petri net concepts.

How does it help with study workflows and model analysis?

The app supplies an analysis-oriented workflow rather than classroom management. Users can save and load projects for ongoing study, inspect mathematical properties via the built-in analysis engine, and export understanding through generated trees. Tagliaferro designed the tool to provide immediate feedback on model behavior, so learners can iterate models and compare results without moving to desktop analysis software.

Practical mobile lab for formal modeling, best for higher-education learners

PetriNets is a practical option for university students and researchers who want portable, hands-on practice with Petri nets and state-space reasoning. Expect it to suit learners already studying formal methods rather than complete novices. Tip: use short, focused modeling sessions and save incremental project versions to explore single properties per session for clearer learning outcomes.
