摘　　要：为提高突发事件级联失效对物流网络破坏程度的评估的可信性,提出一个考虑物流网络边权特征的节点重要度的综合度量方法,并在此基础上构建相应的级联失效模型。数值仿真结果表明:该模型对于物流节点重要度的衡量更为完善,所制定的失效负载分流准则及其对于级联失效破坏性的评估结果更具合理性。通过该模型可更加全面地掌握了解网络结构对于级联失效破坏的抵御能力,为物流应急管理提供理论支持。In order to improve the credibility of destruction assessment after cascading failure caused by emergen -cy in logistics network , a method is proposed to evaluate the comprehensive importance of the node quantitively based on the logistics network structure with edge weight , and then a cascading failure model is established .The simulation results have showed that it is helpful for more objective quantization of logistics node importance using this model .And it is also more reasonable to make the corresponding redistribution rule and to assess the de -struction of cascading failure .It helps more in knowing about the resistance ability for cascading failure , and providing theoretical support for logistics emergency management .
