Abstract：Concerning the incomplete fuzzy decision information system with a dominance relation, according to the analyses on the advantages and disadvantages of two dominance relations, a new total order dominance relation was built by using the probability distribution principle of the attribute value. This relation was used to reasonably improve the extended dominance relation and overcome the shortcoming that the limited dominance relation cannot be used to compare all the objects in the domain. And further, based on the new relation, the expression of the lower and upper approximate, the definition of relative reduction and specific calculation method were given. Finally, an example verifies the effectiveness of the proposed method.
