摘要 定义了对象甄选信息系统,并根据属性值序列间的距离,给出了对象的相似关系,并利用Rough集理论讨论了对象的分类问题,最后给出了甄选的优化模型. This paper defines the selecting object information system and the similitude relation of objects according to the distance of attribute value sequence, discusses the classify of objects using variable precision rough sets theory and finally gives the optimized model of selecting object.
