基于局部特征的南极考察站网络效率评价

Optimized efficiency evaluation method for Antarctic research station network based on local features

为评价不同站点布局下南极考察站网络运行效率,本文提出基于局部特征的南极考察站网络效率评价方法。通过基于最小二乘理论的层次分析法(AHP)计算点/边相对重要性指标权重,然后利用优劣解距离法(TOPSIS)对点/边相对重要性进行综合排序,反映网络局部特征;在此基础上,对已有网络效率评价模型进行修正,得到整体网络相对运行效率,实现“点-边-网络”层层深入的效率评价。应用此方法分别分析中国、美国和澳大利亚等国家的南极考察站网络运行效率,结果表明该方法适用于不同结构网络的运行效率评价,可为未来新建南极考察站选址或整体布局调整提供参考。

To evaluate the Antarctic research station network efficiency under different site layouts,an optimized network efficiency evaluation method was proposed based on local properties.The relative importance of points and edges was evaluated,based on Analytic Hierarchy Process(AHP)and Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS),to represent the local properties of the network.The relative importance was substituted in the modified network efficiency model to obtain the operational efficiency of the network.This method was used to analyze the operational efficiency of China’s,the United States’and Australia’s Antarctic research station networks.This method is suitable for efficiency evaluations of different networks,which can provide a reference for site selection or overall layout adjustments of new Antarctic research stations in the future.
