模糊决策在动车线路选择中的应用

The Application of Fuzzy Decision in the Selection of Bullet Train Routes

本文根据影响动车选线的基本因素,应用层次分析法和模糊决策理论,对三种动车选线方案进行综合评判。选取了效益、便捷和安全环保3个方面的9个主要影响因素建立模糊综合评判的指标体系,运用层次分析法确定了各因素的权重。运用模糊决策理论确定了动车选线的最优方案。

In this paper, according to the basic factors that affect the scheme optimization of bullet train routes, three kinds of route schemes are chosen for comprehensive evaluation by using the analytic hierarchy process (AHP) and the fuzzy decision theory. Choosing the nine main influencing factors with respect to efficiency, convenient, safety and environmental protection, the index system of comprehensive evaluation is established. Using the analytic hierarchy process, the weight matrix of different influence factors is obtained. The optimal proposal is determined according to the fuzzy decision theory.
