## CSP-OZ-DC: a combination of specification techniques for processes, data and time.(English)Zbl 1088.68643

Summary: CSP-OZ-DC is a new combination of three well researched formal techniques for the specification of processes, data and time: CSP, Object-Z, and Duration Calculus. This combination is illustrated by specifying the train controller of a case study on radio controlled railway crossings. The technical contribution of the paper is a smooth integration of the underlying semantic models and its use for verifying timing properties of CSP-OZ-DC specifications. This is done by combining the model-checkers FDR for CSP and UPPAAL for timed automata with a new tool $$f2u$$ that transforms FDR transition systems and certain patterns of Duration Calculus formulae into timed automata. This approach is illustrated by the example of a vending machine.
