Abstract:

Resilience can comprehensively describe the ability of equipment system-of-systems (SoS) to absorb or recover from strikes or interferences, reflecting the comprehensive performance of the SoS. A computational evaluation method is proposed to assess the resilience quantitatively and to evaluate the importance of combat network links of equipment SoS. Firstly, the definition of equipment SoS resilience is provided and a mathematical model for quantifying resilience is established. Secondly, a link importance index based on the resilience-added value is proposed to recognize critical links and a combat network link importance evaluation model is constructed accordingly. Thirdly, various recovery strategies are presented and their effects on the performance recovery of combat network are analyzed. Finally, the applicability and rationality of the proposed method is verified via a simulation case. Experimental results demonstrate the theoretical contribution of the paper to the architecture optimization of equipment SoS, which ensures and improves the combat performance of SoS. Also, this research lays a critical foundation for further research on relevant combat network applications based on the equipment SoS resilience.

Key words: equipment system-of-systems (ESoS), resilience, combat network, link importance evaluation, recovery strategy
