Yager  developed the ordered weighted averaging (OWA) operator and applied in decision making problems. Xu & Yager  developed some geometric aggregation operators, such as the intuitionistic fuzzy weighted geometric (IFWG) operator, the intuitionistic fuzzy hybrid geometric (IFHG) operator and gave an application of the IFHG operator to multiple attribute group decision making with intuitionistic fuzzy information. Xu [2007e] and Xu & Chen [2007a, 2007b] also developed some arithmetic aggregation operators for decision making problems.
