Abstract :
Aiming at the risk problems during the bidding of IT project, this paper introduces a multilayer bidding risk decision model of IT project evaluation based on rough set and fuzzy set, which integrates the advantage of the two theories. The subjectivity of weight choice is avoided by analysis of history project data based on rough set; the complexity of computation is reduced by attributes reduction of inconclusive indexes. Then the combination of a method of fuzzy comprehensive evaluation can integrate all experts´ opinions effectively and eliminate inconsistent factors during the process of experts marking. Finally, an example is given to demonstrate the algorithm of the decision model
