现实的群体决策,不仅取决于群体中每个成员的偏好,而且取决于成员间的协调,这种成员间的二元关系,文中称之为协调关系。本文针对三种不同的现实群体决策中的二元关系,提出了三种以协调关系为自变量的群体偏好函数,来研究这种群体决策问题。 Realistic group decision-making depends not only on the preference of each member of the group, but also on the coordination among the members. The binary relationship among these members is herein referred to as the coordination relationship. In this paper, we propose three group preference functions based on the coordination relationship as an independent variable to study the binary decision-making in the three different groups.
