A Multi-Phase Resilience Evaluation Method for Cross-Domain Unmanned Swarms

Cross-domain unmanned swarms can execute complex combat missions across different spatial domains. Resilience directly impacts the overall combat effectiveness of swarms in complex environments. Traditional resilience evaluation methods for unmanned swarms rarely consider the spatial distribution characteristics and the temporal characteristics of the combat process. To address these, this paper proposes a multi-phase resilience evaluation method for cross-domain unmanned swarms. First, the failure modes within cross-domain unmanned are analyzed, and possible resilience strategies for cross-domain unmanned swarms are given. Then, a multi-phase resilience process model, including prevention, degradation, recovery, and reconfiguration, is proposed, as well as its corresponding resilience metrics, namely resistibility, robustness, recoverability, and reconfigurability. Then, a multi-phase comprehensive resilience model for cross-domain unmanned swarms is given. Finally, a case study is given and analyzed for demonstration and verification. This study can provide a different perspective for guiding the multi-phase resilience design of cross-domain unmanned swarms.
