The weight of factors is an important process in IT project risk analysis.After discussing the relative methods of factor weight evaluation,some problem in the traditional ways were pointed out,the concept of the combination weight was put forward,and a way to assess its weight based on rough set was given.According to the combination weight and the matrix of similarity coefficient,the risk factors in IT projects were classified by cluster analysis to make the correct decision for project management
