| 摘 要： | 道路选择问题是地震灾后应急救援必须解决的问题之一。为了对救援道路进行合理的选择,需要对灾区道路危险性进行综合评价。现有的综合评价中较少考虑归一化方法的选取对评价结果的影响,该文使用EM(Entropy Method)改进TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution)对汶川地震道路危险性进行综合评价,发现了不同的归一化方式会对评价结果产生不同程度的影响。通过对其影响因素进行分析,探讨合适于EM改进TOPSIS的灾区道路危险性综合评价归一化方式,其结果对地震灾后道路选择提供了新的思路。

| Abstract: | The problem of road selection is one of the problems that must be solved in emergency rescue after the earthquake.In order to make a reasonable choice of rescue roads,it is necessary to comprehensively evaluate the road hazards in the disaster area.Existing comprehensive evaluations seldom consider the influence of the selection of normalization methods on the evaluation results.This article uses Entropy Method(EM)to improve Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS)to comprehensively evaluate the road hazard of the Wenchuan earthquake and find that different normalization methods will have different degrees of impact on the evaluation results.Through the analysis of its influencing factors,the normalization method of comprehensive evaluation of road hazards in disaster areas suitable for EM to improve TOPSIS is discussed.The results provide new ideas for road selection after the earthquake. |
