In this paper,we propose a pure linguistic hybrid arithmetic averaging(PLHAA)operator,which is based on pure linguistic weighted.arithmetic averaging(PLWAA)operator and extended ordered weighted averaging(EOWA) operator,and the multiple attribute group decision making(MAGDM) problems under pure linguistic information,in which all expert weights,attribute weights,attribute values take the form of linguistic labels are studied.A method based on the operators for MAGDM under pure linguistic information is presented.Also,the method is straightforward and takes the known linguistic information into account sufficiently.Finally,the method is applied to the partner selection in the field of supply chain management.%本文给出了建立在纯语言加权算术平均(PLWAA)算子和推广的有序加权平均(EOWA)算子基础上的纯语言混合算术平均(PLHAA)算子,研究了专家权重、属性权重及属性值均以语言形式给出的纯语言多属性群决策问题,提出了一种纯语言多属性群决策方法.该方法计算简洁方便且能充分利用已有的决策信息.最后将该方法应用于解决供应链管理领域中的合作伙伴选择问题.
