属性间有优先级别关系的语言分布评估算子

Language Distribution Evaluation Operator with Priority Level Relationships Between Attributes

由于客观事物的复杂性和不确定性、以及人类思维的模糊性,决策者在对诸如学生的综合素质、汽车的性能等定性属性进行评估时,往往用语言描述的形式给出评估信息。本研究基于语言分布评估加权平均(DAWA)算子、语言分布评估有序加权平均(DAOWA)算子、优先平均(PA)算子与优先有序加权平均(POWA)算子,提出了属性间具有优先级别关系的语言分布评估集结(PDAA)算子与属性间具有优先级别关系的语言分布评估集结(PDAOWA)算子。

On account of its complexity & uncertainty on objective things and ambiguity of human thinking, the decision makers sometimes would like to provide assessment information by means of language description when they are assessing qualitative attributes about the students’ comprehensive quality and car’s performance. This paper puts forward PDAA&PDAOWA, which have precedence relations among attributes on the basis of DAWA, DAOWA, PA& POWA.
