基于复杂网络的装备保障网络结构脆弱性分析

Structural Vulnerability Analysis of Equipment Support Network Based on Complex Networks

通过网络化实现装备保障一体化是装备保障体系建设的重点问题。在分析复杂网络脆弱性基本理论的基础上,通过定义装备保障网络中节点、边,构建了典型的装备保障网络拓扑结构模型,提出了装备保障网络的随机失效和蓄意攻击失效两种失效模式,并对两种失效模式下不同装备保障网络的结构脆弱性进行了仿真分析,为装备保障网络的构建以及防护策略的制定提供了科学的参考依据。研究结果表明:从防御角度而言,适当增加不同保障实体之间的交叉连接有助于提高装备保障网络的抗毁性;而从攻击角度而言,二次攻击则可有效提高攻击效率,以达到迅速瘫痪装备保障体系的目的。

It is the key issue of the construction of equipment support systems that the integration of equipment support is realized by networking. Based on analysis of the basic theory of complex networks structural vulnerability, the nodes and links in the equipment support network are defined, and the topology model of typical equipment support network is built; the random failure and deliberate attack failure for the equipment support network is put forward,and the simulation of structural vulnerability under the different topology model and different mode of failure for the equipment support network is carried out, and the research provide reference for the construction and protection of the equipment support network. The results shows that setting more links between the different equipment support units can improve the invulnerability of equipment support network with the purpose of defense. On the other hand,the mode of attacking based on the evaluations of the last attack can upgrade the efficiency rapidly with the aim of paralyzing the equipment support network.
