摘　　要：随着社会与科技发展,基础设施网络之间的相互关联日趋复杂。为研究它们之间的关联关系对网络带来的影响,在对基础设施网络进行物理结构特性分析的基础上,提出一种基于网络图和泰森多边形的基础设施网络建模方法,在模型构建的基础上,研究对比网络独立运行和关联运行时效能的变化以及网络中不同节点故障对网络效能的影响。实验结果表明:故障在关联基础设施网络之间的传播比在独立网络中更为迅速,受故障影响,网络效能下降速度更快;网络中不同节点失效对网络效能影响程度不同,基础设施网络间的关联关系会使节点的重要性发生改变。这一结论为发现和识别网络中基础设施网络重要节点,加强重要节点的预防保护和故障发现后的应急策略提供了理论依据与决策支持。Along with the development of society,science and technology, the relationships among infrastructure net- works gradually become more and more complicated. In order to analyze the impact of their correlations on the net- works,on the basis of studying the physical structure characteristics of infrastructure networks,this paper proposes a network graph and Tyson polygon-based infrastructure network modeling method. According to the model, the change of the network operation efficiency and the influence of different node failures in the networks on network operation efficiency under independent and correlative operation conditions are compared and studied. The simulation results show that the spreading speed of the failure and the descending speed of the network efficiency in correlative infra- structure network are faster than those in independent operation network. In the networks, the influences of different node failures on network efficiency are different, and the correlation relationship among infrastructure networks will change the node importance. This conclusion provides the theoretical basis and strategic support for discovering, iden- tifying and protecting the infrastructure network key nodes, and taking emergency strategy when failure happens.
