To incorporate the decision makers' confidence levels in the decision making process, in this study, we shall propose some intuitionistic fuzzy confidence weighted geometric operators, including the improved intuitionistic fuzzy confidence weighted averaging (IIFCWA) operator, the improved intuitionistic fuzzy confidence weighted geometric (IIFCWG) operator, the improved generalized intuitionistic fuzzy confidence weighted averaging (IGIFCWA) operator and the improved generalized intuitionistic fuzzy confidence weighted geometric (IGIFCWG) operator. Some desirable properties and special cases of the proposed aggregation operators are also discussed. Finally, based on the new aggregation operators, a novel approach is proposed to solve the multiple attribute decision making with the intuitionistic fuzzy information, and a numerical example is given to illustrate feasibility of the proposed method.
