Abstract:This chapter presents an approach for certified design of railway critical systems. This approach, which realizes the software development cycle, relies on metamodeling architecture and model-transformations. It combines semi-formal UML models and formal models in order to check, proof and generate code by refinement; we use the process algebra FSP to check the dynamic behavior and B to generate proved code. Initially, the authors select an UML subset, which could be uses to model the key aspects of critical s… Show more
