摘　　要：为了减轻群体评价中少数评价者的错误或偏见对群体评价结果的影响,提出基于变权向量的群体评价信息集结方法.根据各评价者的评价值与基于线性加权法的群体评价值的差别,确定了一个变权向量,给出了基于该变权向量的变权集结算子.实例分析表明,将该变权集结算子用于群体评价的信息集结,可以有效减轻少数评价者的错误或偏见对群体评价结果的影响.In order to reduce the effect of few evaluator＇s mistake and prejudice on the result of the group evaluation, a method of group evaluation information aggregation based on variable weights vector is introduced. According to the differences between each evaluator＇s evaluation and the group evaluation obtained by the linear weighting method, a variable weights vector is determined, and a variable weights aggregation operator based on the variable weights vector is defined. Finally, an aggregation example is given. The result shows that this aggregation method can effectively reduce the effect of some evaluator＇s mistake and prejudice on the result of the group evaluation.
