基于模糊层次分析法的高速公路网立交枢纽选址研究

Study on the Problem of Interchange Hub Location Based on Fuzzy Analytic Hierarchy Process Method

针对目前高速公路立交枢纽选址中存在的问题,对高速公路网中的立交枢纽所处区域的各种因素进行了分析,建立了对应的评价指标体系,采用模糊层次分析法对该体系以及立交枢纽选址的特点进行了分析处理,提高了选址决策的效率。通过对简单算例的分析运算,证明了该方法应用于立交枢纽选址问题中的可行性和有效性。

For the problems of the interchange hub location, based on the analysis of the factors in the area of the interchange hub locating, the corresponding appraisal index system is set up. Combining the characteristics of the interchange hub location problems, the fuzzy analytic hierarchy process is adopted, which is the organic fusion of the analytic hierarchy process and the fuzzy synthetically evaluation, in order to improve the decision-making efficiency. Finally, through the operation of the simple numerical example, it proves the feasibility and validity of this method applying into the interchange hub location issues.
