【摘要】 多粒度的语言术语是刻画决策问题不确定性差异程度的有效方式。文中定义了语言信息函数和多粒度语言判断矩阵对应的导出矩阵,在此基础上提出了多粒度语言判断矩阵完全一致性和满意一致性的概念,得到了多粒度语言判断矩阵具有完全一致性和满意一致性的充要条件。本文研究为群决策中基于不同粒度的语言判断矩阵有效集结提供了理论依据。更多还原

【Abstract】 Multi-granularity linguistic terms can be described the uncertain difference efficiently in the decision-making problems.Linguistic information function and the corresponding deduced matrices of multi-granularity linguistic judgment matrices are defined in this paper.On the basis of this definition,some new concepts are proposed,such as the consistency,satisfactory consistency of multi-granularity linguistic judgment matrix.We obtain the sufficient and necessary conditions of a multi-granularity linguistic judgment matrix with consistency or satisfactory consistency.The research gives the theoretic basis for aggregating the multi-granularity linguistic judgment matrices effectively in the group decision-making.更多还原
