Resilience evaluation method of combat System-of-Systems based on hierarchical structure

With the innovative development of combat styles, modern warfare has evolved into a confrontation between combat System-of-Systems (SoS). A resilient combat SoS can reduce the loss of capability and achieve rapid recovery in the event of an attack. We innovatively propose a resilience evaluation method of combat SoS based on hierarchical structure, and establish a hierarchical structure for evaluating SoS capability, which is ranked from high to low as capability layer, activity layer, and system layer. Bayesian networks are used to establish mapping relationships between different layers, and the evolution process of SoS capability is obtained based on dynamic Bayesian networks. In addition, a resilience evaluation index based on the evolution process of SoS capability is proposed.
