基于节点修复的网络化指挥信息系统弹性分析模型

摘要

A resilience analysis model of networked command information system based on node repairability was proposed.Firstly,the meaning of networked command information system resilience was confirmed,a network model was constructed,as well as the cascading failures and recovery process were described.Then,based on constructing the load distribution model and the node repairability model,according to the resilience process,a resilience measurement model was constructed.Lastly,the resilience under different model parameters was analyzed.The analytic results show that the recovery probability and mean repairability time of node can affect resilience distinctly,which may provide a guidance for improving the resilience of networked command information system.%提出一种基于节点修复的网络化指挥信息系统弹性分析模型.首先,确立了网络化指挥信息系统弹性的概念,构建了指挥信息系统网络模型,对网络级联失效和恢复过程进行了描述;然后,在建立负载分配模型和节点修复模型的基础上,根据网络化指挥信息系统弹性过程构建了弹性度量模型;最后,进行仿真分析,计算不同模型参数下的网络弹性.结果表明,恢复概率和平均修复时间等参数对网络弹性的影响显著,为提高网络化指挥信息系统的弹性提供了参考.
