Attributes reduction of information system with three-parameter interval grey number
摘要
Abstract
For the incomplete information system, in which the attribute value of alternatives is three-parameter interval grey number, an attribute reduction of information system based on θ-grey dominance relation is proposed. According to the definition of three-parameter interval grey number, the order relation of two three-parameter interval grey numbers based on possibility is presented. On this basis, a θ -grey dominance relation between attribute value is established. At last, the attribute reduction of this type of incomplete information system is put forward combined with the discernibility matrix. An applied example is given to illustrate the usefulness and effectiveness of the proposed method.关键词
