模糊集值信息系统中的决策规则获取研究
Research on Acquisition of Decision Rules in Fuzzy Set-valued Information Systems
【摘要】 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。
【Abstract】 Based on the rough set theory,the set-valued information system was deeply investigated.In such information system,a new reflective relation based on the parameter’s controlling of similarity between two objects was proposed. Furthermore,the set-valued information system was generalized to be a fuzzy one,and the direct method for rules’ acquisition was investigated. Finally,an illustrative example was analyzed.
