    Model-Based Testing Cyber-Physical Systems: Theory and Practice


    Cyber-physical systems are the results of the tight integration of computation, control, and communication. Hence, their mode-based design involves hybrid and multi-disciplinary models addressing discrete behaviour, integrated with continuous dynamics along with (often asynchronous) communication. In this talk, we focus on model-based conformance testing of such systems and present an overview of the theories of conformance testing adapted to this domain. Then, we present some of our ongoing research results towards a practical framework for model-based testing cyber-physical systems. 

    Based on joint work with:  A. Aerts (TU Eindhoven, NL), H. Araujo (F.U. Pernambuco, Brazil), G. Carvalho (F.U. Pernambuco, Brazil),  N. Khakpour (Linneaus U., Sweden), M. Mohaqeqi (Uppsala, Sweden), M.A. Reniers (TU Eindhoven, NL), A. Sampaio (F.U. Pernambuco, Brazil), M. Taromi Rad (Halmstad, Sweden)

    Domains and Event Structures for Fusions (Joint work with Paolo Baldan and Fabio Gadducci)

    Stable event structures, and their duality with prime algebraic domains (arising as partial orders of configurations), are a landmark of concurrency theory, providing a clear characterisation of causality in computations. They have been used for defining a concurrent semantics of several formalisms, from Petri nets to linear graph rewriting systems, which in turn lay at the basis of many visual frameworks. Stability however is restrictive for dealing with formalisms where a computational step can merge parts of the state, like graph rewriting systems with non-linear rules, which are needed to cover some relevant applications (such as the graphical encoding of calculi with name passing). We characterise, as a natural generalisation of prime algebraic domains, a class of domains that is well-suited to model the semantics of formalisms with fusions. We then identify a corresponding class of event structures, that we call connected event structures, via a duality result formalised as an equivalence of categories.We show that connected event structures are exactly the class of event structures that arise as the semantics of nonlinear graph rewriting systems. Interestingly, the category of general unstable event structures coreflects into our category of domains, so that our result provides a characterisation of the partial orders of configurations of such event structures.
