基于高速公路选线方案

Research on Optimal Selection Method of Expressway Line Planning

结合高速公路项目选线的特点，采用层次分析法、模糊综合评价理论等系统分析方法，对高速公路线路方案的选择进行探讨。针对高速公路方案选择既有模糊性又有相对性的特点，建立高速公路选线方案决策系统模糊优化理论模型。

Base on the system analysis theories such as Analytic Hierarchy Process （AHP）, Fuzzy compre- hensive evaluation theory , this paper discusses the line option of expressway after closely analyzing the characteristics of expressway location design and establish a complete. At same time, a decision making model of multi-objective fuzzy optimal selection of variant expressway location projects is developed in ac- cordance with the fuzzy and relative characteristics of the optimal selection of variant projects. This paper considers the decision making of variant expressway location projects as a process of multi-objective fuzzy optimization to make a comparison study between several directions of lines and effectiveness and appraisal of line option.
