不同语言值集下的多属性群决策方法

Approach based on different linguistic-valued sets in multi-attribute group decision making

针对属性权重、偏好信息集及专家权重取自不同的语言值集的群决策问题,给出了"程度"语言值集的选择准则,给出了转换函数,讨论了其性质,提出了不同语言值集下的多属性群决策方法。该方法不仅简洁、直观,而且在决策过程中不丢失任何信息,所得到的结果合理。实例验证了该方法的有效性和实用性。

With respect to multiple attribute group decision making problems with different linguistic-valued sets of attribute weights,preference information and decision makers weights,choice standards of degree linguistic-valued set is given,the transfer function is proposed,and also its properties are discussed.A multiple attribute group decision making method based on different linguistic-valued sets is presented.The method is straightforward and intuitionistic,and no information is lost and the results are reasonable.An example is given to illustrate the validity and practicability of the proposed method.
