节点重要度评价是进行区域综合运输通道布局的重要环节。为准确评价区域节点重要度,基于通道需求影响因素分析,系统地构建了多层综合评价体系。针对模糊综合评价权重难以确定问题,同时为兼顾主观和客观因素,利用修正的熵权法进行权重确定。同时针对传统TOPSIS模型的缺点,引入分层域重合度的概念进行模型改进。最后通过实例分析进行算法说明和适用性验证。%Node importance evaluation is very important in regional comprehensive transport corridor plan -ning.To evaluate the regional node important degree accurately , this paper analyzes the factors that influence the node important degree and builds a multi-level comprehensive evaluation index system .In order to give consider-ations to both subjective and objective factors when determining the weights of indexes , this paper puts forward a method based on ameliorated entropy weight .To overcome the shortcomings of traditional TOPSIS model , this paper puts forward the concept of hierarchical domain contact ratio for model improving .Finally this paper ex-plains algorithms and tests the applicability through case analysis .
