In the paper, we will consider the interval-valued intuitionistic fuzzy multiple attribute group decision making problems. The paper presents a method to derive the weights of experts and to rank the preference order of alternatives based on projection, fuzzy entropy and score functions. Firstly, we obtain the weight of decision makers according to the projection of the individual decision on the mean decision matrix. Then, basing on the score function and fuzzy entropy we develop a practical algorithm to rank alternatives. Finally, an illustrative example is given to verify the developed method and demonstrate its practicality and effectiveness.
