Abstract: With the continuous evolution of equipment support system of systems from traditional hierarchical tree structure to complex network structure, the original research methods and evolution laws can not solve the multi-network evolution problems encountered well. Based on the interdependence among different sub-network nodes, the theory of interdependent network is applied to the evolutionary analysis of equipment support network. The network characteristics of equipment support system of systems are analyzed, and the measures of network robustness are defined based on the maximal connected subgraph and network support efficiency. In the network evolution model, the evolution rules and steps of the model are determined according to the equipment support mechanism, the network interdependency proportional parameter F, which represents the proportion of maintenance, storage and supply nodes with interaction, and the interdependence redundancy parameter K, which represents the average number between some maintenance node and its neighbors in storage and supply network, are defined, and their effects on network robustness are analyzed through simulation. The simulated results of evolution model show that the robustness and overall support efficiency of interdependent network can be improved by controlling the parameters K and F. Key
