摘　　要：　借助决策个体关于方案对的偏比度概念,构建了群体在供选方案集上的a 偏比映射,并证明了该映射满足[胡毓达,系统科学与数学(2003)]中的五个公理和匿名性条件.据此,给出一个群体排序的a 偏比法.With the help of the preference-ratio measure relative to a pair of alternatives for an individual in group decision making, the a-preference-ratio mapping is set up, and it is proved that the mapping satisfies five axioms in paper[Yuda Ha,J.Sys.Sci.& Math.Scis(2003)] and anonymous condition. Finally, a group sequencing is proposed by means of a-preference-ratio mapping.
