| 摘 要： | P-集合(packet sets)是一个动态模型,P-集合是由内P-集合x~F(internal packet set X~F)与外P-集合XF(~Fouter packet set X~F)构成的元素集合对;或者(X~F,X~F)是P-集合.利用内P-集合的结构,给出内P-信息,内P-反动态信息,信息的内P-反动态恢复概念,给出内P-反动态信息的属性合取收缩生成,给出内P-反动态信息与内P-信息同属性定理,给出内P-反动态信息存在与属性合取范式定理,给出信息的内P-反动态恢复属性定理.这些基本理论结果是把内P-集合与一类信息系统故障状态识别交叉,渗透研究得到的.

| Abstract: | P-sets(packet sets) is a dynamic model,which is a pair of element sets composed of internal P-set X~F(internal packet setX~F) and outer P-set X~F(outer packet set X~F),or(X~F,X~F)is a P-set.Using the structure of internal P-set,the concepts of internal P-information,internal P-back dynamic information and information internal P-back dynamic recovery are proposed.The attribute conjunctive shrink generation of internal P-back dynamic information,the identical attribute theorem of internal P-back dynamic information and internal P-information,the existence of internal P-back dynamic information and.attribute conjunctive normal form theorem,the information internal P-back dynamic recovery attribute theorem are put forward.These basic theoretical results are obtained by reseach of internal P-set and a class of information system faults status identification cross and permeates. |
