摘要:P-集合(packet sets)是由内P-集合XF(internal packet set X珔F)与外P-集合XF(outer packet set XF)构成的元素集合对;或者,(XF,XF)是P-集合;P-集合具有动态特性。利用外P-集合XF的结构与动态特性,对它的反动态特性给出研究,提出了基信息、外P-信息、F-补充信息、外P-反动态信息的概念;利用这些概念给出几个基本理论结果,利用这些基本结果,给出外P-反动态信息在信息系统中的应用。
Based on the conception of P(ρ,σ)-set(XP ˉFρ, XPFσ), this paper studied the relation between outer P(ρ,σ)-set and outer P-set: give outer P(ρ,σ)-set and outer P-set relation theorem, outer P(ρ,σ)-set and numerical value σ relation theorem, outer P(ρ,σ)-set's range;studied other characteristics of outer P(ρ,σ)-set: give the finiteness theorem of outer P(ρ,σ)-set, the set chain theorem of outer P(ρ,σ)-set, the outer P(ρ,σ)-set probability interval finite partition theorem, and its corollary; also give generation, reduction, identification theorem of outer P(ρ,σ)-set, filter generation theorem of outer P(ρ,σ)-set; finally give its application.
