摘　　要：基于渗流理论,考虑节点的渗流容量和受上下游失效节点的影响不同,设计了复合网络上下游级联失效策略,采用平均最短路径长度、最大连通子图率和网络全局效率评估B2B2C复合网络的鲁棒性。仿真表明:随着渗流容量系数的增加,网络鲁棒性增强;复合网络对于蓄意攻击的抵抗性较差,平均最短路径长度、全局效率和最大连通子图率呈断崖式下降到0,网络基本瘫痪,而面对随机攻击则具有较好的鲁棒性;与物流网络相比,复合网络平均度低40.6%,幂指数高12.1%,鲁棒性较好。Based on the percolation theory,considering the seepage capacity of nodes and the influence of upstream and downstream failure nodes,the upstream and downstream cascading failure strategy of composite network is designed.The robustness of B2B2C composite network is evaluated by the average shortest path length,the maximum connected subgraph rate and the global efficiency of the network.The simulation shows that with the increase of seepage capacity coefficient,the robustness of the network is enhanced.The composite network is of poor resistance to deliberate attacks,the average shortest path length,global efficiency and maximum connected subgraph rate decrease to 0,and the network is basically paralyzed,while it has good robustness against random attacks.Compared with the logistics network,the average degree of the composite network is 40.6%lower,the power index is 12.1%higher,and the robustness is better.
