综合节点邻域信息下的物流网络级联失效模型构建及分析

摘要

Cascading failure of the logistics network caused by emergency can have great effect on the security operation of the network.For this reason,this paper built a cascading failure model based on the local information of logistics nodes,for studying andanalyzing the effect on the logistics network.The simulation results indicate that:it can resist largely damage caused by cascade failure with less load capacity setting.The more important the node is,the more destructive to logistics network if it failed.The greater the average degree of logistics network,the stronger ability to resist the cascading failure.Lastly; the research has academic guidance significance to enhance the efficient to emergency program and controlefficiency in the logistics network.%级联失效对物流网络的安全运作具有重要影响.基于节点领域信息构建相应的级联失效模型,分析研究物流网络的级联失效问题.数值仿真结果表明:较低的安全负载能力配置可很大程度上抵御级联失效的破坏;重要度越大的节点的失效对网络的平均破坏程度越大;节点平均度越大的网络结构对级联失效的抵御能力越强.这可为物流网络应急规划及应急控制研究提供理论指导.
