P-sets and(,F)-data generation-identification
Shi Kai-quan · Journal of Shandong University · 2009
P-sets which is composed of internal P-sets and outer P-sets,is a set pair and has dynamic characteristic.Based on P-sets,the concepts such as data set,-data set,F-data set and(,F)-data set,and then-data set theorem,F-data set theorem,(,F)-data band theorem,data set recovery theorem,(,F)-data identification theorem and identification criterion are proposed.By using those results,applications of(,F)-data in an information system are presented.P-sets is a new theory and a new method in the research of a dynamic information system.
