Considering the relationship and feedback among the effectiveness indexs, ANP method is widely used in the effectiveness evaluation of the complex system. Based on the effectiveness evaluation process of index weight by ANP method, the shortage of this method in the process of constructing un-weighted super matrix and an improved method based on grey relational analysis are presented in this paper. This improved method overcomes the subjectivity and unreliability in the process of constructing un-weighted super matrix, and increases the objectivity and reliability of the index weight.
