| 摘 要： | 区间直觉模糊信息系统比一般信息系统更能全面、细致、直观地描述和刻画决策信息，对其进行不确定性研究具有重要的意义。利用信息粒度对区间直觉模糊信息系统的不确定性进行了刻画，给出了区间直觉模糊粒度结构的交、并、差、补等四种运算。提出了区间直觉模糊粒度结构上的三种偏序关系，并建立了它们之间的联系。定义了区间直觉模糊信息粒度和区间直觉模糊信息粒度的公理化，并研究它们的性质。 |
| 关 键 词： | 粒度计算 区间直觉模糊信息粒度 偏序关系 公理化 |

| Abstract: | Interval-valued intuitionistic fuzzy information system is able to be more comprehensively,detailedly and visually depict and characterize the decision-making information than the general information system,so reaseaching its research uncertainty is of great importance.With the help of information granularity,this paper characterized the uncertainty of the interval-valued intuitionistic fuzzy information system.It constructed intersection,union,subtraction and complement four operators among granular structures,introduced three new partial order relations in interval-valued intuitionistic fuzzy information systems and established the relationships among them.It defined an interval-valued intuitionistic fuzzy information granularity and an axiomatic approach to interval-valued intuitionistic fuzzy information granularity in interval-valued intuitionistic fuzzy information systems.Finally,it investigated the properties of interval-valued intuitionistic fuzzy information granularity. |
| Keywords: | granularity computing interval-valued intuitionistic fuzzy information partial order relation axiomatization |
