【摘要】 为了能为粒计算的粒提供一种统一的表示形式,分析了粒的对象、特征、关系及状态等4个基本要素,提出了基于数据层面的粒的四元组的形式化表示形式,即由对象集、特征集、关系集和约束集四元组组成。接着给出了几个特殊粒的表示形式,然后说明了该表示形式的统一性,并结合具体的例子进行了研究。该形式化表示形式能够很好地解决基于数据层面的粒的表示问题,有利于问题求解和粒计算理论的研究。更多还原

【Abstract】 In order to provide the granule unification representation of Granular Computing,the paper analyzes the four basic elements of the granule:the objects,the features,the relationships,and the states,presents four-tuples formal representation based on data levels,that is,the object set,feature set,relationship sets and constraints set.Then the representation of several special granules are presented,and it shows the unity of the representation,gives a specific examples to study.The formal representation can solve well the granule representation based on data levels,and it is conductive to problem solving and granular computing theory studying.更多还原
