Abstract:

P-sets(packet sets) is an element set pair composed of internal P-set X(internal packet set X) and outer P-set XF(outer packet set XF), or (X,XF) is P-sets, and it has the dynamic characteristic. Using the structure and dynamic characteristic of outer P-set XF and studying its anti-dynamic characteristic,  the concepts of basis information, outer P-information, F-supplemented information, outer P-anti-dynamic information are given. Based on the concepts, a few of theory results are proposed, by which the application of outer P-anti-dynamic information in the information system is given.

Key words: P-sets; outer P-set; outer P-anti-dynamic information; F-supplemented information
