The Method for Ranking Fuzzy Numbers Based on the Centroid Index and the Fuzziness Degree

摘要

In this paper,the relative geometric dominance degree and fuzziness dominance degree of the fuzzy numbers have been denned based on the centroid of fuzzy numbers and the fuzziness degree, then with the composite of the geometric dominance degree and fuzziness dominance degree, a new ranking method has been proposed. Finally,some comparative examples are used to illustrate the advantage of the proposed method.
