摘要
传统模糊语义方法能较好地处理关于决策方案的语言评价信息,但无法有效地利用决策者针对自己判断的可靠性所提供的语言评价信息。为此,提出了二维语言评价信息的概念及相应的群体决策方法。首先利用主观证据推理理论量化表示二维语言评价信息,并通过冲突分析改进合成规则,解决了二维语言评价信息在复杂强冲突条件下的集结问题,然后设计了相应的择优规则,最后用一个实例检验了该方法的实用性和有效性。
The fuzzy linguistic approaches have been applied successfully to deal with the linguistic assessment information concerning decision alternatives. However, these approaches can not make effective use of the linguistic assessment information concerning the dependability of decision maker＇s subjective judgement. To overcome this limitation, we present a new tool called 2-dimension linguistic assessment information and apply it to group decision making. Firstly, 2-dimension linguistic assessment information is expressed by the frame of subjective evidential reasoning. To aggregate 2-dimension linguistic assessment information reasonably with intricate debate, a conflict analysis method is proposed to improve combination rule. To rank decision alternatives, a corresponding optimization rule is also suggested. In the end, an example confirm practicability and validity of this method.
