基于区域毁伤的基础设施网络抗毁性评估模型

基础设施网络对国家经济、人民生活和社会安全具有重要意义,为了能够准确迅速地评估基础设施网络面对物理攻击或自然灾害时的抗毁性,提出了基于区域毁伤的基础设施网络抗毁性评估模型。该模型将网络的边均分成虚拟节点,提出加权聚类算法寻找关键区域,使用归一化方法平衡网络规模和网络地理覆盖范围对评估结果的影响,算法复杂度低,运算量小,模型应用范围广,便于多个网络之间或同一网络不同规划方案的抗毁性比较。以智利电力输送网络为例,设计多组实验对评估模型进行检验,并给出可视化结果和分析。

Survivability assessing model of infrastructure networks based on regional damages

The infrastructure networks are of great significance to the national economy, people's livelihood and social security. In order to assess network survivability under the physical attacks and disasters, the evaluation model of network survivability based on the regional damages is provided. The model divides the edges of network into virtual nodes, and a weighted clustering algorithm is proposed to find critical areas of the network. Normalization method is used to suppress the influence of network size and area on the assessment result. The model is of less complexity, requires less calculation and is convenient for various networks or the same network with different designs comparing. Chile electric power grid is used as experimental data to test the evaluation model and provide visualization results and analysis.
