Abstract: To deal with the fuzzy service indicators efficiently,an evaluation method was proposed which combined the intuitionistic fuzzy set and information axiom.The membership and non-membership of the evaluation needed to be considered synthetically which was transformed from the evaluation value and the hesitation degree given by the decision makers.Integrating the evaluation value of all the decision makers was a necessary step before calculating the information divergence between the system range and design range by intuitionistic fuzzy cross entropy.The rank of the all alternatives was obtained according to the information contents of alternatives calculated by the proposed method.An example of elevator product service conceptual evaluation was illustrated.By comparing with the fuzzy information axiom,the proposed approach which considered the hesitation degree of decision makers was more efficient and accurate.
