Resilience Analysis of Coupling Combat Network: Considering Multiple Destruction-Recovery Processes

Modern military force operates in the form of combat systems of systems (CSoS) involving multiple components assembled in terms of function and structure with abundant complex relationships, which can be abstracted as the coupling combat network (CCN). However, coupling failures render the CSoS more vulnerable and challenging to recover under external disturbances. As the battlefield environment grows increasingly variable and future operations confront high-intensity conflict, it is necessary for the CSoS to consider resilience against continuous strikes as well. As such, this paper proposes an analysis framework of resilience based on the CCN modeling. Then, considering multiple and continuous strikes from enemies, a resilience modeling and assessment method is developed based on trend analysis for multiple destruction-recovery processes (DRPs). Additionally, the notion of importance is introduced into the resilience analysis of the CCN, wherein the correlation of layers’ resilience is investigated, encompassing both direct and coupling resilience importance. Finally, the CCN model for a typical CSoS is established to illustrate the proposed method and framework, which can serve as a reference for research on CSoSs’ resilience.
