Abstract: When a seaport is attacked and fails, cascading failure effect will be generated in the seaport-dry port container transport network due to the connectivity between ports, which will then spread to the whole network. To this end, this paper conducts a study on the robustness of seaport-dry port container transport networks under cascade failure. This paper designs different state indicators for seaport nodes and dry port nodes, establishes load transfer equations for invalid nodes based on the node failure propagation capability and inter-node gravity model, constructs a cascade failure model and robustness assessment index for seaport-dry port container transport network, and explore the impact of the failure propagation capability threshold of neighbor node, the amount of node redundancy, the proportion of port hopping, the change in the number of cooperative dry ports at seaports and different node attack modes on network robustness, it also explores the change in business volume of its competing ports after the failure of the seaport. The results show that there is an optimal value interval for the node failure propagation capacity threshold and the hopping port ratio in terms of enhancing robustness performance; increasing the node tolerance parameters within a certain range can help reduce the impact of network cascading failures; and the extent of overlap of the dry ports with which the seaports cooperate should not be too high; competing seaports will take a share of the business of the invalid seaport, which is related to the distance between the two ports and the operational capacity of the competing seaport.

Key words: integrated transportation, failure propagation, cascade failure model, seaport- dry port container transport network, robustness

摘要: 当海港受到攻击而失效时,由于港口间的连通关系,会在海港一陆港集装箱运输网络中产生级联失效效应,进而扩散到整个网络中。为此,本文研究海港一陆港集装箱运输网络级联失效下的鲁棒性,设计海港节点与陆港节点的不同状态指标,根据节点失效传播能力与节点间引力模型建立失效节点负载转移方程,构建海港一陆港集装箱运输网络级联失效模型和鲁棒性评估指标,探讨邻居节点失效传播能力阈值、节点冗余量、跳港比例、海港合作陆港数量变化,以及不同节点攻击方式对网络鲁棒性的影响,同时,探究在海港失效后,其竞争港口的业务量变化。结果表明,在增强鲁棒性能方面,节,点失效传播能力阈值与跳港比例存在最优取值区间;在一定范围内提高节,点的容差参数有助于降低网络级联失效的影响:同时,海港所合作的陆港重叠范围不应过高;竞争港口会瓜分一部分失效海港的业务份额,其业务份额与两港口之间的距离和竞争港口的作业能力相关。
