江苏省干线航道网络抗毁性研究

Research on Invulnerability of Jiangsu Trunk Waterway Channel Network

为准确评估江苏省干线航道网络的抗毁性,文中利用Space L法构建网络拓扑结构模型,在分析网络特征的基础上选用不同的抗毁性测度指标定量衡量网络在不同攻击策略下的抗毁性能表现.结果表明:江苏省干线航道网络不具备无标度特性和小世界特性,对随机攻击策略的抗毁性强于蓄意攻击策略,且重新计算参数攻击策略对网络的破坏性高于初始参数攻击策略,尤以重新计算介数攻击策略对网络破坏性最强.最终依据仿真结果,提出了网络抗毁性优化措施.

In order to accurately evaluate the invulnerability of Jiangsu Province’s trunk waterway network,a network topology model was constructed by using Space L method.On the basis of analyzing the characteristics of the network,different invulnerability indicators were further selected to quantitatively measure the invulnerability performance of the network under different attack strategies.The results show that the trunk waterway network in Jiangsu Province does not have scale-free and small-world characteristics,and its invulnerability to random attack strategy is stronger than deliberate attack strategy.Moreover,the attack strategy of recalculating parameters is more destructive to the network than the attack strategy of initial parameters,especially the attack strategy of recalculating betweenness is the strongest.Finally,according to the simulation results,the network invulnerability optimization measures are put forward.
