Modeling and verification of interactive behavior for cyber-physical systems

Abstract

Energy Consumption Interaction Automata (ECIA) is presented to model cyber-physical systems' interaction behavior and energy consumption constraint information. The component-interaction automata is an excellent model for specifying architecture and behavior information, but fails to depict energy consumption constraint information in cyber-physical systems. ECIA extends the description ability of component interaction automata by binding each action with an energy consumption interval. ECIA models of cyber-physical systems can be composed together based on the ECIA composition definition we presented in this paper. Applications of ECIA, such as specifying and verifying components' interaction properties in the design stage of developing component-based cyber-physical systems, are discussed. An example is given to demonstrate how ECIA can be used to analyze the energy-related properties of components' behavior in cyber-physical systems.
