With respect to fuzzy AHP group decision-making problem in which the result is fuzzy number, a new method of fuzzy AHP is presented based on set-valued statistics. Firstly the definition of uniformly interval number judgment matrix is given; secondly interval number weight vector is calculated based on interval number eigenvector method. At last, a real number result is derived. An example is given to demonstrate the feasibility and rationality of the proposed method. Compared with gray relational analysis method, it is more simply and conveniently.
