A Resilience Assessment Method for Equipment System-of-Systems (ESoS) Based on Network Percolation

The 2022 Russia-Ukraine conflict has revealed that contemporary warfare, characterized by informatization, involves distinct elements of system-of-systems confrontation. Research on the resilience of equipment system-of-systems (ESoS) is crucial for effectively accomplishing combat missions and selecting robust combat forces. This paper presents an assessment method for assessing ESoS resilience based on network percolation. Specifically, the performance of the ESoS is evaluated by quantifying the number of operation loops. Subsequently, the concepts of degradation resilience and recovery resilience are introduced, based on observed changes in ESoS performance. To measure the resilience of the ESoS, a comprehensive resilience metric is proposed based on network percolation. Finally, the feasibility and effectiveness of the proposed method is validated using a military case. The analysis results demonstrate that the proposed method not only expands the application scope of percolation theory but also provides a novel approach and perspective for assessing ESoS resilience.
