%X 实际问题中，事物的一些属性值介于某个范围之间，常被用来刻画信息系统中的不确定信息。为了表达这种情况，属性值通常用模糊区间来表示，这种信息系统就是区间值模糊信息系统。本文通过在带有决策的区间值模糊信息系统中引入优势关系，建立区间值模糊决策序信息系统。在此基础上构造部分一致函数来简化知识的表达，并获得部分一致约简的判定定理，通过可辨识属性集和可辨识矩阵提供不协调的区间值模糊序信息系统的部分一致约简的具体方法，并结合投资风险这一具体案例的求解分析，进一步阐述了对部分一致约简研究的意义，丰富了区间值模糊序决策信息系统中的粗糙集方法。</br>In practical problems, some attribute-values of things are within a certain range and this is often used to describe uncertainties in an information system. The attribute-value is often expressed by a fuzzy interval, and the information system in this case is then called an interval-valued fuzzy information system. This paper establishes an interval-valued fuzzy decision ordered information system by introducing dominance relationships. This partially consistent function was built to simplify knowledge expression. A judgment theorem for partially consistent reduction was obtained, and from the recognizable attribute set and recognizable matrix, a partially consistent reduction method for an inconsistent interval-valued fuzzy ordered information system was derived. Furthermore, by combination with a specific case study on venture investment, the significance of partially consistent reduction is explained. This experiment enriches the rough set method for interval-valued fuzzy ordered decision information systems
