摘要
群体一致性的优劣和群决策结果的优劣密切相关。针对基于语言信息的群决策问题,本文从改善群体一致性的角度提出了一种分析方法。在该方法中,考虑专家可能给出的语言短语、语言区间变量形式的评价信息以及残缺信息,建立以群体一致性偏差最小为目标函数的优化模型;通过求解该模型得到群体方案排序值,使得群体方案排序或优选结果能够反映每个专家的意愿。最后给出了一个算例。
The quality of group consensus is closely related to that of group decision result.An analysis method based on improving consensus is developed in this paper to solve the group decision making problem with linguistic information.In the method,the assessment information on alternatives provided by experts can be represented in linguistic term,interval linguistic variable and incomplete information.In order to minimize the deviation of group consensus,an optimization model is constructed.The collective ranking values of alternatives are obtained from the solution to the optimization model.The method makes the collective opinion on ranking of alternatives or selection of the most desirable alternative（s）reflect each expert ＇s opinion.Finally,an example is provided to illustrate the use of the proposed method.
