以集值信息系统为研究对象,提出了一种使用参数控制对象间相似程度的自反二元关系。接着,将集值信息系统拓展为模糊的形式,研究了其中的决策规则获取方法,进行了实例分析。
Taking the set-valued information system as the research object, this paper proposes a reflexive binary relation that uses the parameters to control the similarity between objects. Then, we expand the set-valued information system into a fuzzy form, study the method of obtaining the decision rules and carry out an example analysis.
