A Model-based Approach for the Modeling and the Verification of Railway Signaling System
Résumé
Railway Signaling System aims at resolving interoperability problems of railway signaling and train control/command. An European system is taken place to guarantee interoperability between international borders. Such complex systems require a high-level of safety. We propose an approach for modeling and verifying railway signaling systems. Our approach consists of graphical modeling such systems and automatically generating formal specification in Event-B. It is based on model-driven engineering techniques. We propose model-to-model transformation to generate Event-B model from UML class diagram profiled with safety and railways concepts. A textual Event-B code is also automatically generated using model-to-text transformation. The proposed approach allows to formally verify the safety of railway signaling systems based on model checking and animator tool.
