Abstract: Firstly the comparable methods set and compatible methods set are defined based on possible comprehensive evaluation methods in this paper,and compatible methods set is recognized by using fuzzy cluster analysis method.Then possible combinational evaluation set is confirmed based on compatible methods set,and evaluation methods integration model is set up to find the most satisfactory combinational evaluation. Thirdly the compatibility of the combinational evaluation conclusions is discriminated.Finally a practical example is given to show the effectiveness of the research in practice.

Key words: comprehensive evaluation method, compatible methods set, combinational evaluation
