| 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。 |
| 英文摘要: |
| Node importance evaluation is very important in regional comprehensive transport corridor planning. 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 considerations 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 explains algorithms and tests the applicability through case analysis. |
