基于Vague集的互通式立交方案综合评价方法

互通式立交方案评价是立交设计工作中的重要环节,而方案比较指标体系的建立和指标综合评价又是设计中的关键。根据模糊集的推广形式—Vague集,提出基于Vague集的互通式立交方案综合评价方法。通过计算Vague集之间相似度量,得出最优方案与各备选方案之间的接近程度,从而寻求对立交方案评价的量化,并结合实例进行验证。

Synthetic Evaluation Method for Interchange Scheme Based on Vague Set

The evaluation for interchange scheme is an important part in design of overpass,while the establishment of scheme comparing index system and synthetic evaluation for index are critical factors.In accordance with the popularized form of fuzzy set-Vague set,this paper puts forward a synthetic evaluation method for interchange scheme based on Vague set.The proximity between the optimal scheme and various candidate schemes is obtained by calculating the similarity numbers among Vague sets so as to seek the qua...
