Abstract:In order to solve the problems that the current methods of index weight determination overemphasized subjective experience in scheme comparison for railway rout selection, and subtle changes in weight would directly affect the selection results, a method of index weight determination for scheme comparison in railway location designs based on deviation-G1 method was proposed through introducing the basic idea of above two theories. From this method, the objective information of index data and subjective opinions of experts were all taken into account, which made the determination of index weight become more scientific and reasonable. Then, the linear optimization method was used for sensitivity analysis on the obtained weights. The range of index weight to ensure the taxis result of scheme was worked out so as to judge the stability of the decision-making conclusion. Finally, an example of local alignment scheme comparison was used to illustrate the operation procedure of the method.
