摘　　要：为探究区间值信息系统的相似性问题,首先分析了区间数之间的相似度,提出了一种新型的相似度公式,并对其性质作了分析和研究;其次定义了一种相似性置信测度,来衡量区间值信息系统中某对象在全局中的相似性程度;最后在宿舍分配问题中,给出一种行之有效的决策方法,为教育教学中的决策问题提供理论支撑。In order to explore the similarity of interval-value information systems,the similarity between interval values was analyzed and a novel similarity degree formula was proposed and its properties were explored.Secondly,a similarity confidence measure was defined to measure the similarity degree of some object in interval-valued information systems.Lastly,an effective decision-making method with reference to dormitory allocation was presented and a theoretical support for decision-making in education was provided.
