In this paper, we extend the power geometric (PG) operator and the power ordered weighted geometric (POWG) operator [Z.S. Xu, R.R. Yager, Power-geometric operators and their use in group decision making, IEEE Transactions on Fuzzy Systems 18 (2010) 94-105] to Atanassov's intuitionistic fuzzy environments, i.e., we develop a series of generalized Atanassov's intuitionistic fuzzy power geometric operators to aggregate input arguments that are Atanassov's intuitionistic fuzzy numbers (IFNs). Then, we study some desired properties of these aggregation operators and investigate the relationships among these operators. Furthermore, we apply these aggregation operators to develop some methods for multiple attribute group decision making with Atanassov's intuitionistic fuzzy information. Finally, two practical examples are provided to illustrate the proposed methods. (c) 2013 Elsevier B.V. All rights reserved.
