Application Study Of Fuzzy Mathematic For Aggregating Group Decision's Preferences

Group Decision has played a great role in decision science, and the study of aggregating preferences' methods combined fuzzy mathematic has been a recent topic in Group decision science' .As to the problem, the paper first studied the uniform methods for the different preference information, based on the many research productivities, the paper tends to uniform the different kind of preferences as Fuzzy Complementary Judgment Matrices, and then the paper gave a method based on Ordered Weighted Averaging(OWA) operator and Fuzzy Complementary Judgment Matrices to aggregate preference information. In the paper an IOWA operator was presented to extend the application of OWA operator, IOWA operator based on OWA operator and possibility degree ca,n operate interval number. Finally the paper gave two numerical examples, and analyzed them.
