Abstract

Cyber-Physical Systems (CPS) are integration of computation and physical processes connected through networks. The high complexity of cross-domain engineering in combination with the pressure for system innovation, higher quality, time-to-market, and budget constraints make it imperative for engineers to use integrated engineering methods and tools for CPS design. However, existing computer-based engineering tools are mainly focused on a particular domain and therefore it is challenging to perform system-level analysis for CPS due to the difficulty of knowledge integration from different domains. This thesis studies the problem in the modeling of cross-domain CPS. Problems in the modeling of both functional and non-functional requirements during CPS design are explored and a functional model-based approach is proposed for high level CPS modeling. Moreover, targeting the security requirement in CPS, which is one of the key non-functional requirements in CPS, physics-based models and solutions are proposed in this thesis.
