Resilience theory plays a vital role in the practical design of modern engineered resilient systems composed of cyber-physical systems and components having interdependencies intended to make the entire system robust. In this paper, the percolation-based metric is applied to measure the communication systems’ resilience and efficiency. Because there is no consistent and reliable way to measure resilience, the percolation-based metric framework is developed to model the component or system failure by removing fractions of the nodes or links, causing the network to transition from functional to non-functional. The utility of the percolation-based metric model is demonstrated by using the power grid and maritime platform systems (legacy and future design versions) as case studies. The results from analyses of the maritime communication and power grid systems are presented. The results indicate that percolation-base metric may be a useful approach for system engineers and designers to gain improved insight into the quantification of communication system resilience and efficiency.
