摘要： 针对目前常用决策理论的不足，在计算机群体决策支持系统（GDSS）的偏好agent 中用一种模糊数~N 模拟决策者的心理偏好，采用相关参数表达决策者的性格特征等个性因素。从决策人的角度出发，提出了一种偏好集结模型，使群体综合偏好照顾到个性因素，为群体决策提供了一个新的思路。

Abstract: To overcome the shortcoming of present usual theory, in the paper, a kind of fuzzy number is used to simulate the decision makers’mind preference in preference agent in group decision support system. The individual factors such as characteristic are expressed with someparameter. And a model of incorporating preference is proposed based on individual to unite the group consensus and the individual factors. Themethod brings out a new enlightenment in group decision making.
