基于区间直觉二元语义集的专家权重确定方法

摘要

为提高语言评价集表达方式的合理性,根据语言变量和区间直觉模糊集相结合定义区间直觉语言集的思路,提出区间直觉二元语义信息的概念;针对属性值为区间直觉二元语义信息的多属性群决策问题,考虑专家对方案每个属性的熟知程度不同,通过使用个体评价信息辨别区分度、个体与群体的相似度以及个体与其它个体邻近度3个准则确定专家权重判断矩阵.通过算例验证了该方法的可行性与有效性.%To improve the rationality of language expression sets,depending on the idea of the combination of language variables and interval-valued intuitionistic fuzzy sets to define the intuitionistic linguistic set,the notion of interval-valued 2-tuple linguistic set was proposed.For the multiple attribute group decision making problems based on the concept of interval valued 2-tuple linguistic set,the expert weight matrix was established using three criteria of distinguishing discrimination degree,similarity of individuals and group and proximity of individual and other individuals.The numerical examples illustrate the proposed method is feasible and effective.
