本研究用实验室研究方法对 MAU决策辅助对个体和群体决策质量的影响进行了比较研究 ,结果表明 :(1 )使用 MAU决策辅助时 ,群体决策不仅在信息利用上优于个体决策 ,而且在多数心理效标上也占优势 ;(2 )在 MAU方法的利用效率上 ,只在任务较难时 ,群体决策更优于个体决策 ,且群体决策时间明显长于个体决策 ;(3 )不使用 MAU决策辅助时 ,个体决策和群体决策在心理效标上无显著差异 ,但群体决策在信息加工效标上优于个体决策。
In this study, we compared the impact of MAU decision-making on individual and group decision-making quality using laboratory research methods. The results show that: (1) When using MAU decision aiding, group decision-making is not only superior to individual decision-making in information utilization, (2) On the utilization efficiency of MAU method, the group decision-making is better than the individual decision-making only when the task is more difficult, and the group decision-making time is significantly longer than the individual decision-making; (3) Decision support, individual decision-making and group decision-making no significant difference in the psychological standards, but group decision-making in the information processing efficiency is better than the individual decision-making.
