A Method for Fuzzy Decision Making Problem with Triangular Fuzzy Complementary Judgment Matrix

The aim of this paper is to investigate the fuzzy decision making problem, in which the decision information takes the form of triangular fuzzy complementary judgment matrix. Some new concepts such as triangular fuzzy complementary judgment matrix, modal value complementary judgment matrix, left deviation matrix and right deviation matrix, etc., are defined. Based on error analysis, a priority method for triangular fuzzy complementary judgment matrix is proposed. The decision alternatives are ranked by the priority formula of triangular fuzzy numbers.
