摘要
P-集合(packet-sets)具有动态特性,它是由内P-集合XF-(internal packet set XF-)与外P-集合XF(outer packet set XF)构成的集合对(X-F,XF)。利用P-集合,给出-F-数据离散区间、F-数据离散区间的概念;利用这些概念,给出信息系统输出数据的数据离散区间特征,给出数据过滤概念;提出数据离散区间定理、数据还原定理、数据过滤定理、数据过滤剩余与数据辨识定理,给出应用。P-集合是研究信息系统输出数据变化的一个新理论与新方法。
P-sets （packet-sets） has dynamic characteristics. It is a pair of sets consisting of internal P-set X^F（internal packet set X^F） and outer P-set X^F（outer packet set X^F）. By using P-sets, the concepts of F-data discrete interval and F-data discrete interval are given. By using these concepts, the characteristics of data discrete interval for outputting data in information system as well as the concept of data filtering are provided. Meanwhile, the following theorems are proposed： the theorems of data discrete interval, the theorems of data recovery, the theorems of data filtering, the theorems of data filtering residue and data identification. Finally, the application is given. P-sets is a new theory and method to study the changes in the output data of information systems.
