A Decision-making Method for Highway Route Selection Based on Subjective-objective Combined Weights-FCE
In order to solve the problem of not being objective of traditional routing effect evaluation methods,this paper studies on the decision-making method of mountain highway routing in the complex environment,taking Guiyang-Pingtang Expressway as an example.The results show that:1)The constructed evaluation index system for decision-making of highway routing in mountainous areas can effectively and objectively reflect the complex environmental characteristics of mountainous areas,and is geographically applicable;2)The subjective and objective assignment method of Delphi + CRTIC reduces the subjectivity of the assignment and improves the objectivity of the weight distribution while retaining the mature experience of experts;3)The highway routing decision-making method based on the combination of subjective and objective weights-FCE takes into account economic,technical,geographic and other indexes.The decision-making method considers economic,technical and geographical indicators,and improves the objectivity and scientificity of the routing decision-making scheme through fuzzy comprehensive evaluation and subjective-objective combination weights.
