摘　　要：物流网络在突发事件下易发生级联失效现象,给网络的抗毁性带来巨大影响。针对物流网络中级联失效扩散机理的认知对于提高应急对策的有效性及控制效率具有重要意义。因此基于物流网络特征构建级联失效模型,分析研究级联失效的传播对物流网络抗毁性的影响。数值仿真结果表明:以物流中心为代表的II类中转型节点的失效对网络抗毁性的影响最大。物流节点间业务联系紧密程度及网络结构均对网络抗毁性产生重要影响。Logistics network is easy to incur the cascading failure under the emergency. And it has a great effect on the survivability of logistics network. So it is of very important significance to understand the propagating mechanism of cas-cading failure on the logistics network, because it will enhance the efficience to emergency program and control efficiency. For this reason, a cascading failure model of logistics network is built based on these characteristics,for studying and analyzing the network’s survivability. The simulation results indicate that if the II kind of logistics nodes represented by logistics center fail, it has the most destructive to logistics network’s survivability. And different coupling relationship of logistics nodes and different logistics network structure also have a major impact on it.
