Abstract The ordered weighted averaging (OWA) operator was introduced by Yager.1 Thefundamental aspect of the OWA operator is a reordering step in which the input arguments are rearranged indescending order. In this article, we propose two new classes of aggregation operators called ordered weightedgeometric averaging (OWGA) operators and study some desired properties of these operators. Some methodsfor obtaining the associated weighting parameters are discussed, and the relationship between the OWA and DOWGAoperators is also investigated. © 2002 Wiley Periodicals, Inc.
