7、lti-CriteriaDecisionMaking（MCDM）;variableweights摘要：为克服经典多准则决策（MCDM）方法不适应动态的决策环境、难以反映方案集对准则集的非线性反馈效应等方面缺陷，通过运用网络分析和数据包络分析技术，提出一种动态环境下的群组专家多准则变权决策方法。较之于经典MCDM方法，新方法主要创新之处在于：给出了MCDM模型的动态演化机理；通过专家对方案所处准则状态予以有偏好（无偏好）判断，提出一种保证信息无损的群组专家信息提取方式；实现了对方案的变权评价，有效反映出蕴含在系统内部的准则集
8、与方案集的非线性交互作用关系。实例验证结果表明，所提方法是科学可行的，能够有效解决救灾方案动态优选、供应商动态评价等实践问题。关键词：动态环境；群组决策；多准则决策；变权文献标志码：A中图分类号：N94doi：10.3778/j.issn.1002-8331.1408-00841引言问题近年来一直是系统
