Abstract
With regard to the fuzzy multi -attribute decision making problems about route and station alternatives comparison of high -speed railway,an evaluation system and a decision method for route and station alternatives comparison of high -speed railway based on triangular fuzzy numbers is proposed.Firstly,the qualitative and quantitative index values of alternatives comparison are converted into the triangular fuzzy numbers.Then the in-dex weights are obtained by a linear programming model based on the maximal deviation of weighted index val-ues.Finally,the alternatives are ranked and the optimal is selected according to the closeness degree and projec-tion of the weighted index values of each alternative on the fuzzy positive and negative ideal point of alternative. In conclusion,an example of route and station alternatives comparison is illustrated to show the effectivity and feasibility of this method.关键词
