Recursive ECATNets‐based approach for formally verifying System Modelling Language activity diagrams

Abstract

System Modelling Language (SysML) is a modelling language that allows system description with various integrated diagrams. The SysML activity diagram (SAD) is widely used to graphically describe system behaviours. Nevertheless, despite the various advantages of SysML, it lacks for formal semantics to achieve the verification of behavioural requirements. Petri nets (PNs) are a popular technique for modelling and verifying the dynamic behaviours of systems. Recursive ECATNets (RECATNets) not only take all the advantages of PNs but also allow concise specifications and more capabilities for the verification process. In this study, the authors propose an approach which describes a verification methodology of SADs based on their transformation into RECATNet models. Case studies are presented to show the benefits and the usefulness of the proposed approach.

Formal modeling and verification of UML Activity Diagrams (UAD) with FoCaLiZe

“…Another approach consists of translating a UML activity diagram into CPN (Colored Petri Nets) specifications [28,4] to attribute a formal semantics for UML activity diagrams and verify their properties. Recent contributions focus on the verification of SysML activity diagrams through their translation into Recursive RECATNets [29] and into Modular Petri Nets [30]. Yet here, neither OCL, action constraints nor activity partitions are considered.…”

SysML model-driven approach to verify blocks compatibility

“…These transformations are generally implemented and offered as tools which can assist architects during the verification of their systems. Many of these works are dedicated to generate formal models from UML and SysML diagrams (Rehab and Chaoui (2015)) (Aouag et al (2014)) (Rahim et al (2015)), which are considered as informal models. In fact, the sequence diagram, which is a shared model between UML and SysML, was be the matter of many transformation works.…”
