A Methodology for Model-based Development and Safety Analysis of Transport Systems

We present a method to engineer the control software of transport systems and analyze their safety using the Reactive Blocks framework. The development bene ts from the model-based approach and makes the analysis of the systems at design time possible. The software is analyzed for freedom of collisions and other spatiotemporal properties by combining test runs of already existing devices to find out their physical constraints with the analysis of simulation runs using the verification tool BeSpaceD. This allows us to discover potential safety hazards already during the development of the control software. In particular, we introduce a methodology for the engineering and safety analysis of transportation systems and elaborate its practical usability by means of a demonstrator based on Lego Mindstorms.
