公路网综合评价权重确定方法

在分析已有不同权重确定方法的基础上，提出了新的组合赋权方法。运用系统聚类分析和斯皮尔曼等级相关系数对不同赋权方法所得评价结论进行相容性检验，由此确定相容方法集，并用斯皮尔曼等级相关系数来检验相容方法集中不同方法评价结论的密切程度，以此为基础，确定组合权重计算公式中的加权系数并进行组合赋权。将此组合赋权方法应用于公路网综合评价，融合了不同方法的权重信息，使所得结论更加合理。

Weight Value Determination Method of Road Network Comprehensive Evaluation

Based on the analysis of different weight value determination methods, a new combination weighting approach is put forward. Firstly the compatibility of all different evaluation conclusions is discriminated by using hierarchical cluster analysis and Spearmen grade correlation coefficient. Therefore, a compatible methods set is gained. Then, the relationship of different conclusions in compatible methods set is tested with Spearmen grade correlation coefficient. According to the above results, the weighting coefficient of a formula, which is used to calculate combination weight, is determined. Finally, an example of road network comprehensive evaluation is introduced to show the feasibility of the method, which blends weight information of various methods and makes the conclusion more reasonable.
