【摘要】：结合区间不确定性语言集与比例二元组,提出区间值比例二元组的概念;基于得分函数与精确函数,给出了两个区间值比例二元组的比较方法,并介绍了区间值比例二元组与区间数之间的转换函数;在此基础上,提出区间值比例二元组加权几何算子及区间值比例二元组有序加权几何算子;针对不同语言标度的群决策问题,通过统一标度给出了相应的多属性群决策方法,并将其用于投资商投资过程中。
[Abstract]:The concept of interval valued proportional binary group is proposed based on interval uncertainty language set and proportional binary group, and the comparison method of two interval valued proportional binary groups is given based on score function and accurate function. The transformation function between interval valued proportional binary group and interval number is introduced, on the basis of which, the weighted geometric operator of interval valued proportional binary group and ordered weighted geometric operator of interval valued proportional binary group are proposed. Aiming at the problem of group decision making with different language scales, the corresponding multi-attribute group decision making method is given through unified scale, and it is applied to the investment process of investors.
