Research on the interval-valued multiple attribute decision model based on the α-β dominance relation

The interval-valued information system is a generalized form of a single-valued information system. In this paper, four existing dominance relations and the α dominance relation are analyzed. And a new α-β dominance relation is proposed for multiple attribute decision of the uncertain attribute weights problem. Furthermore, an interval-valued multiple attribute decision model based on the α-β dominance relation is defined. Finally, performances of the α dominance relation and the α-β dominance relation are compared through a teacher evaluation case. Results show that the proposed method improves classification accuracy.
