    Abstract

    When developing safety-critical systems, it is necessary to satisfy not only functional requirements defining the set of tasks to be performed by the system, but also safety requirements describing the characteristics the system should possess in order to ensure proper safety. Reliability is, as well, an acute issue in the development of safety-critical systems. Enhancement of safety and reliability can be achieved by applying formal methods, while complexity of large systems can be mastered using a graphical language for modelling, e.g., UML. Here we introduce a UML-based development process that incorporates safety analysis and provides a logical interface to a formal refinement based development in B-action systems. The tools associated with the B Method provide a good mechanised support for proving the correctness of the development within B-action systems. We show the feasibility of our development process within a healthcare case study where we develop a safety-critical drug discovery system.
