Abstract: In this paper，an iterative method is proposed to deal with the group decision-making problem with incomplete fuzzy preference relations.The method is guided by additive consistency property and only uses the preference values provided by the experts without needing other information，and hence，the estimating results by the method is in good consistency with the experts’ original preference and is more believable.Finally，a numerical example is presented to illustrate how to utilize the method proposed in this paper.
