TAPAAL and Reachability Analysis of P/T Nets
نویسندگان
چکیده
We discuss selected model checking techniques used in the tool TAPAAL for the reachability analysis of weighted Petri nets with inhibitor arcs. We focus on techniques that had the most significant effect at the 2015 Model Checking Contest (MCC). While the techniques are mostly well known, our contribution lies in their adaptation to the MCC reachability queries, their efficient implementation and the evaluation of their performance on a large variety of nets from MCC’15.

Soundness of Timed-Arc Workflow Nets
Analysis of workflow processes with quantitative aspects like timing is of interest in numerous time-critical applications. We suggest a workflow model based on timed-arc Petri nets and study the foundational problems of soundness and strong (time-bounded) soundness. We explore the decidability of these problems and show, among others, that soundness is decidable for monotonic workflow nets whi...
متن کاملUndecidability of Coverability and Boundedness for Timed-Arc Petri Nets with Invariants
Timed-Arc Petri Nets (TAPN) is a well studied extension of the classical Petri net model where tokens are decorated with real numbers that represent their age. Unlike reachability, which is known to be undecidable for TAPN, boundedness and coverability remain decidable. The model is supported by a recent tool called TAPAAL which, among others, further extends TAPN with invariants on places in o...
متن کاملA Forward Reachability Algorithm for Bounded Timed-Arc Petri Nets
Timed-arc Petri nets (TAPN) are a well-known time extension of the Petri net model and several translations to networks of timed automata have been proposed for this model. We present a direct, DBM-based algorithm for forward reachability analysis of bounded TAPNs extended with transport arcs, inhibitor arcs and age invariants. We also give a complete proof of its correctness, including reducti...
متن کاملSoundness of Timed-Arc Workflow Nets in Discrete and Continuous-Time Semantics
Analysis of workflow processes with quantitative aspects like timing is of interest in numerous time-critical applications. We suggest a workflow model based on timed-arc Petri nets and study the foundational problems of soundness and strong (time-bounded) soundness. We first consider the discrete-time semantics (integer delays) and explore the decidability of the soundness problems and show, a...
متن کاملTAPAAL: Editor, Simulator and Verifier of Timed-Arc Petri Nets
TAPAAL is a new platform independent tool for modelling, simulation and verification of timed-arc Petri nets. TAPAAL provides a stand-alone editor and simulator, while the verification module translates timed-arc Petri net models into networks of timed automata and uses the UPPAAL engine for the automatic analysis. We report on the status of the first release of TAPAAL (available at www.tapaal....
