Modeling and Resilience Analysis of Combat Systems-of-Systems Based on Kill Web

A reasonable assessment of combat systems-of-systems (CSoS) resilience is of great value to the improvement and optimization of the CSoS structure, to improve weapon construction efficiency, and building a CSoS that adapts to intelligent warfare requirements and fulfills missions. From the SoS point of view, this paper proposes a CSoS modeling and resilience analysis based on the kill web. First, analyze the characteristics of the kill web. The CSoS is modeled based on the standard combat loop and the generalized combat loop. Second, the scope of resilience assessment is divided according to performance changes. The combat effectiveness, which considers the number of combat loops, combat capabilities, and time efficiency, is used as an index to measure performance changes. According to the changes in combat effectiveness, a resilience assessment method is proposed. Finally, a military example is used to calculate the resilience index to verify the feasibility and effectiveness of the proposed method. The results show that the proposed resilience evaluation model is consistent with the actual situation and can well measure SoS resilience.
