摘要 针对基于语言评价信息的多指标群决策分析中群体一致性程度计算问题,依据近年来最新发展的二元语义及其算子和PA算子,给出了一种用于集结语言评价信息的L PA算子,并基于L PA算子,进一步给出了关于群体一致性程度的计算步骤.最后给出了一个算例. With respect to the computation problem of group consensus degree in multi-criteria group decision making problems with linguistic assessment imformation,in this paper,a LPA operator(Linguistic Power Average) is proposed to aggregate linguistic assessment information based on the two-tuple linguistic representation developed in recent years and PA operator(Power Average),and then,the steps are given to compute group consensus degree according to LPA operator.Finally,a numerical example is given to illustrate the method proposed in this paper.
