摘　　要：针对专家偏好信息权重未知的基于语言偏好关系的群体评价问题提出了一种解决方法。首先,采用序关系分析法和唯一参照物比较判断法指导专家表达偏好信息;其次,在对专家偏好信息形式转换的基础上,定义了2个基于二元语义的诱导有序加权平均算子对权重未知的专家偏好信息进行集结,从而得出群体评价结论;最后,给出了一个应用算例。With respect to group evaluation problems with linguistic preference relations on alternatives,an analysis approach is proposed. First,the rank correlation analysis and the sole reference judgment analysis are used to guide the experts to express preference information. After the transform of the partial information of the experts,two induced ordered weighted averaging aggregation operators for two-tuple are proposed for the experts＇ preference information with ignorance of weight. And the ranking of alternatives is obtained by comparison of two-tuple linguistic information. Finally,an application example is given to illustrate the approach proposed.
