研究了一类决策者对方案的偏好信息具有多样性的群体决策问题。提出了一种新的方法来处理具有两种不同形式偏好信息的GDM问题：模糊偏好关系和乘性偏好关系。建立了一个双目标优化模型，将两种形式的偏好关系整合起来，计算方案的排序值。使用该方法，基于所获得的排序值直接进行备选方案的排序或最期望的备选方案的选择。数值例子也被用来说明所提出的方法的使用。
The purpose of this paper is to study a group decision-making (GDM) problem in which the preference information about the alternative provided by the decision makers can be of a diverse nature. A new method is presented to deal with the GDM problem with two different formats of preference information on alternatives: fuzzy preference relations and multiplicative preference relations. A two-objective optimization model is constructed to integrate the two formats of preference relations and compute the ranking values of alternatives. Using this method, the ranking of alternatives or selection of the most desirable alternatives is directly done based on the obtained ranking values. A numerical example is also used to illustrate the use of the proposed method.
