Resilience Assessment Method for Air Defense Kill Web Based on System Dynamics Model

In complex battlefield environments, quantifying resilience assessment remains a challenging issue for air defense kill webs. Existing research lacks modeling capabilities for the dynamic evolution mechanisms of operational processes, resulting in deviations between evaluation outcomes and actual battlefield resilience performance. To address this deficiency, this paper proposes a resilience assessment method for kill webs based on system dynamics modeling. We construct an operational evolution model incorporating target tracking, resource status, and task allocation, conducting comparative analyses of system recovery capabilities between pre-deployed backup strategies and non-backup strategies. The study demonstrates that predeployed backup strategies can significantly enhance system disturbance resistance capability in resource-damage scenarios through redundant resource pre-positioning and dynamic task reorganization mechanisms. Furthermore, the triggering timing of backup strategies and resource scheduling priorities directly influence the performance recovery speed during the restoration phase. This research provides a novel assessment framework and theoretical insights for improving the resilience of air defense systems.
