摘　　要：研究基于群决策的带有偏好约束的数据包络分析(DEA)模型.针对群决策中偏好形式的多样性,在对不同偏好一致化的基础上,将各决策者的偏好集结成群组偏好,以此作为反映权重的主观信息.进一步将此信息与DEA模型中反映权重的客观信息集成,构造出一种基于群决策的DEA模型,最后给出了算例.According to the diversity of preference forms, based on uniformity of the different forms of preference information in group decision making, this paper first aggregates the preference information provided by every (decision) maker to form group's preference information, which makes it the subjective information which (reflects) weight, and integrates the subjective information and the objective information which reflects weight in DEA model, then constructs a new DEA model based on group decision making. Finally, a numerical example is given.

关 键 词：群决策 数据包络分析 偏好约束
