Modeling and Analyzing Reliable Cyber-Physical Systems Based on Aspect Orientation

Abstract

Cyber-physical systems (CPS) consists of distributed computation interconnected by computer networks. Finding a common semantics among these diverse components that facilitate system modeling, synthesis, and verification is a significant challenge of CPS. Aspect oriented method is proposed to model and analyze reliable CPS, Petri nets are used to observe behaviors of basic component, such as device, computation and physical interaction, component and communication process. The reliability assurance strategy of CPS is proposed, aspect orientation is used to weave it into the base net. Based on this, the effectiveness and feasibility of proposed method are analyzed based on the operation semantics of Petri nets. A case study of material balancing system and experimental results demonstrate that the approach can contribute to the improvement of design quality in developing reliable CPS.
