Abstract
The optimal selection of railway alignment is often a complex system engineering,which requires schemes as much as possible to be recommended and compared from multiple perspectives and multi levels.So it is a process of multi-objective and comprehensive decision-making.The traditional methods of optimal railway alignment schemes mainly consider the investment of the project,at the same time,qualitatively compare the other indicators,and then evaluate the schemes.However,due to lack of comprehensive decision-making information,it is difficult to select the optimal scheme if the differences of economic indices related to alignment are not prominent.The entropy weight and ideal point method is applied to optimizing the selection of the high-speed railway from Tongchuan to Fuxian of Xi'an-Yan'an High Speed Railway.On the basis of comprehensive consideration of the factors influencing the alignment schemes,the comprehensive evaluation index system of the project is established,and the proposed alignments are evaluated comprehensively.The evaluation results show that the entropy weight and ideal point method has higher reliability and can be used as reference for decision-makers in the selection of railway alignment schemes.关键词
