Abstract: In the face of some problems in scale-group evaluation,such as how to aggregate the information of individual to group information effectively, how to reflect the affection of group consensus in comprehensive evaluation, a method of group evaluation based on distribution information of attribute-value is proposed in this paper. Firstly, distribution-interval variable is used to describe group information by construct the distribution of every attribute, and the interval variable weighted average algorithm operator(IWAA) based on the definition of algorithms of distribution-interval variable is put forward. Secondly, design the rank method of distribution-interval variable is designed. Finally, a numerical example shows the validity for the proposed method.
