Abstract

Abstrcat To the problem of aggregation and expression of bias with linguistic assessment information in the multi-attribute group decision making, the bias expression,the bias aggregation and the alternative selection of experts based on cloud model are studied. Cloud model is used to express the linguistic assessment information given by each decision maker. The power of attribute and decision maker is calculated by the mood arithmetic of cloud. The bias aggregation is executed by means of floating cloud. The order and alternative of selection is determined according to the relative distance of cloud model. The burring and randomicity of assessment is fully expressed in this method.
