In this paper, we develop an improved ranking strategy for fuzzy multiple attribute group decision making. First, we introduce a method for multiple attribute group decision making and show that method can not choose the best alternative, when S((P) over tilde (i)circle minus(P) over tilde (j)) = 0 and (P) over tilde (i) not equal (P) over tilde (i). We define then a k-order deviation of the fuzzy sets and propose an improved ranking strategy, we also propose an improved method for fuzzy multiple attribute group decision making. Finally, the results of a numerical example demonstrate the effectiveness of this new method.
