Multi-domain Modeling of Cyber-Physical Systems Using Architectural Views

Designing cyber-physical systems (CPSs) increasingly requires the use of multi-domain models throughout the development process. Ensuring consistent relationships between various system models is an important part of an integrated design methodology. This paper describes an architectural approach to reasoning about relations between heterogeneous system models. The run-time base architecture of the system is used as a unifying representation to compare the structure and semantics of the associated models. Each model is related to the base architecture through the abstraction of an architectural view, which captures structural and semantic correspondences between model elements and system entities. The use of the architectural view framework to relate system models from different domains is illustrated in the context of a quadrotor air vehicle.
