利用2元组方法建立了一个语言值决策模型和LOW A算子模型,这两个模型具有可操作性强和语义明确等优点,特别是充分利用了语言值所含的信息,提高了决策结果的精度.最后,利用这两个模型给出了基于语言值的多属性群决策方法,同时给出一个应用实例. The two-tuple method is used to establish a linguistic value decision model and a LOW A operator model. These two models have the advantages of strong operability and clear semantics. In particular, they make full use of the information contained in linguistic values ​​and improve the decision-making results Finally, we present a multi-attribute group decision-making method based on linguistic values ​​by using these two models, and give an application example.
