考虑边失效程度的物流网络级联失效模型

Logistics Network Cascading Failure Model with Edge Failure Consideration

在实际交通运输过程中,备选边的拥挤程度对驾驶员的路径选择产生一定的影响。在传统级联失效模型的基础上,结合驾驶员的心理趋好,构建了考虑边失效程度的物流网络级联失效模型,并运用Matlab软件进行仿真分析,仿真结果表明,在相同的网络环境下,考虑边失效程度的物流网络表现出更高的稳定性,且更早达到平衡状态。该模型能更加真实客观地对实际物流网络的稳定性进行评判,进一步为物流配送突发级联失效下的物流企业做出应急路径选择提供理论支持。

In this paper, based on the traditional cascading failure model, and in connection with the psychological tendency of the drivers, we established a logistics network cascading failure model that considered the degree of edge failure. Then using the Matlab software,we simulated the model, with results showing that under the same network environment, the logistics network with edge failure consideration was more stable and quicker to reach equilibrium.The model established could more realistically assess the stability of actual logistics network in practice, and further provide theoretical support for logistics enterprises concerning emergency route selection in the event of outbreak cascading failure of the logistics distribution network.
