基于TOPSIS模型的机场网络节点重要度评估

在机场网络中单个机场节点的失效往往会对其他的节点产生影响,特别是关键节点的失效会波及整个网络.准确客观的识别重要节点机场关乎整个机场网络的安全运营.本文分析了机场网络拓扑特性中的度、集聚系数和接近度指标,考虑了机场旅客吞吐量和所在城市人口等交通经济特性指标,使用熵权法确定权重的基础上,应用TOPSIS法构建综合评价体系模型,最后以华东地区机场网络为例进行节点重要度排序.结果表明与单一指标的评估结果相比,该方法更加全面客观的确定不同属性指标的权重,避免了不同指标取值的差异性,使评价更加全面,更符合机场网络实际运营情况.

Evaluation on Airport Network Node Importance Based on TOPSIS Model

In the airport network,the failure of a single airport node can often affect other nodes,especially the failure of key nodes affect the entire network.Therefore,accurately and objectively identifying key nodes is of great significance to the effective operation of the entire network.In this paper,the complex theory was used to analyze the topological characteristics of the network.On this basis,the traffic economic characteristics of the airport nodes were considered,the weight of each index was determined by the entropy weight method,and then the TOPSIS method was used to build a comprehensive evaluation system model.Finally,the airport network in East China was taken as an example to rank the importance of nodes.The results show that this method is more comprehensive and objective in determining the weights of different attribute indexes compared with the evaluation results of a single index,avoids the difference in the values of different indexes,and make the evaluation more comprehensive and more in line with the actual operation of the airport network.
