| 摘 要： | 经济圈交通枢纽综合评价中存在信息不确定、定性评价指标较多的问题,而传统的评价方法虽然简单直接,但容易受到主观因素的众多干扰.提出了一种基于粗糙集的灰色关联分析综合评价方法,将基于粗糙集理论的指标赋权法与灰色关联综合评价相结合,通过粗糙集理论对指标进行约简并给出较为客观的指标权重,得出综合评价模型以及相应的算法;通过算例说明了该方法的有效可行.

| Abstract: | Transport hub comprehensive evaluation in the economic cycle has the problems of the information uncertainty and too many evaluation indicators.The traditional evaluation methods are simple and direct but can be easily interfered of many subjective factors.So the method of grey analysis comprehensive evaluation based on rough sets was put forward.This evaluation method combined the indicators weight based on rough set theory and the grey comprehensive evaluation method,and got the objective weight of indicators from filtering the original indicators and standardizing the importance degree of indicators.Then,comprehensive evaluation model and corresponding arithmetic were summed up.Finally,the sample illuminated the validity and feasibility of this comprehensive evaluation method. |
