Abstract: Aiming at the multiple attribute decision making of the interval rough numbers with parameters, firstly, the paper defines the mean and variance of interval rough numbers with parameters, then based on the degree of dominance about interval rough numbers with parameter in mean and variance, it finds the positive and negative ideal point. Secondly, it proposes deviation degrees of interval rough numbers with parameters in an integral form. By means of the concept of the rough existing weighted interval distance averaging operator（WIRDAA）, it also builds the entropy method based on the MADM of the interval rough numbers with parameters to get the final order. Finally it applies an example to illustrate the feasibility of the method.

Key words: interval rough numbers, multiple attribute decision making, deviation degrees, entropy method
