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,基于物流运输的有向性及网络边权结构构建相应的级联失效模型。数值仿真结果表明,该模型对于边失效后的负载分流准则的制定以及对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并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 failures caused by emergency in logistics network, a cascading failure model is established based on the influence of transportation directions and the logistics network structure with edge weights. The simulation results show that it is also more reasonable to make up the corresponding redistribution rule and to assess the destruction of cascading failures by using this model. It helps understand the resistance ability to cascading failures, and provides theoretical support for management emergency in logistics network.
