An approach to integrating four types of preference information in multi-attribute decision making

This paper studies the multi-attribute decision making problem. Based on the translation formulas of four types of preference information (represented by means of preference orderings, utility values, complementary judgement matrix and reciprocal judgement matrix), this paper first makes the information uniform, using complementary preference relations, then utilizes the priority formula of complementary judgement matrix to rank the alternatives. Finally, a numerical analysis is given.
