A treatment method for urban rail transport project benefit information to ensure the multiple benefit factors based on rough set

Ensuring the weight of benefit factors is an important process of urban rail transport projects benefit analysis. Based on the analysis of similar methods and studies, the paper points out the existing problem in researches on urban rail transportation project of the single benefit factor through either traditional methods or rough set. Therefore, theory of rough set is used to set up models of multiple benefit factors in urban rail transport project. At last, empirical analysis is carried out which provides supports for urban rail transportation project management and decision.
