摘　　要：为有效识别关键节点以分析抗毁性,通过建立空铁联运双层加权网络模型搭建分析框架,提出一种基于熵权的综合中心度关键节点识别方法,针对东航空铁联运客运网络进行关键节点识别与节点重要性排序,进而分析不同攻击模式下东航空铁联运网络的抗毁性。研究结果表明:东航空铁联运双层网络的关键节点在不同子网络层的分布呈非均衡性;联运网络在随机性攻击模式下的抗毁性较强,而在选择性攻击模式下的抗毁性较弱,然而,当攻击节点比例较低时,联运网络在2种攻击模式下的抗毁性差别并不大,攻击节点达到一定比例后,选择性攻击下的抗毁性才会显著弱于随机性攻击;2种攻击模式下,东航空铁联运双层网络的抗毁性均优于其子网络层。This paper proposed an identification method of key nodes based on the comprehensive centrality of entropy weights by building a double-layer weighted network model of air-rail inter-modal transport to construct the analytical framework. The key nodes were identified and the importance of nodes was ranked for the air-rail inter-modal passenger transport network of China Eastern Airlines. Further, the paper analyzed the invulnerability of the air-rail inter-modal transport network of China Eastern Airlines under different attack modes. The results show that the distribution of key nodes is uneven in different sub-network layers of the double-layer network. The invulnerability of the network is strong under the random attack mode but weak under the selective attack mode. However, the difference in invulnerability under the two attack modes is not large when the proportion of attacked nodes is low. The invulnerability of the network under the selective attack mode is significantly weaker than that under the random attack mode after the attacked nodes reach a certain proportion. Under either of the two attack modes, the invulnerability of the double-layer network of air-rail intermodal transport is better than that of its sub-network layers.
