Abstract
- In this paper, the reliability performance analysis of coupled cyber-physical systems under different network types is investigated. To study the underlying network model, their interactions, and relationships and how cascading failures occur in the interdependent cyber-physical systems, we propose a practical model for interdependent cyber-physical systems using network percolation theory. Besides, for different network models, we also study the effect of cascading failures effect and reveal mathematical analysis of failure propagation in such systems. Then we analyze the reliability of our proposed model caused by random attacks or failures by calculating the size of giant functioning components in interdependent cyber-physical systems. In order to gain an insight into the proposed analysis model, numerical simulation analysis is also provided. The results show that there exists a threshold for the proportion of faulty nodes, beyond which the cyber-physical systems collapse. We also determine the critical values for different system parameters. In this way, the reliability analysis based on network percolation theory can be effectively utilized for anti-attack and protection purposes in coupled cyber-physical systems. [ABSTRACT FROM AUTHOR]
