Abstract: The Ordered Weighted Aggregation（OWA） operator only considers the ordered position of the given argument and few considers the given argument itself in the aggregation of data information. An induced Ordered Weighted Geometric Averaging（IOWGA） operator is presented, which not only considers the ordered position of the given argument but also consider the given argument itself, and some properties are proved. Then aggregation method of decision information based on the induced aggregation operator is scientific and reasonable by theoretical analysis. At last, the method is proved that can more scientifically reflect the real situation by comparative analysis with the common aggregation operators.
