基于规则的专家系统时间估计研究

在一些复杂控制系统中,专家系统作为一个决策控制器,满足整个系统的性能需要,因此研究专家系统的推理时间是必要的.专家系统的推理时间与其推理模式、知识库结构等因素有关.针对知识库结构,探讨了基于规则的专家系统的推理时间问题,利用时间齐次马尔可夫链为专家系统知识库建模,并给出了相应的时间估计模型.

Time Model in Rule-Based Expert Systems

 In some complex control systems,expert systems,as a decisive controller,consist in the whole systems,so much more studies on inferring time are necessary for them.Inferring time in expert systems relates to its inference mode,knowledge－base architecture,computer performance,and provided languages.This paper takes the knowledge－base architecture as an example to study the corresponding problem of the alignment.At last,Temporally homogeneous Markov chain is used to model for knowledge－base.Time assessing mathematics model is given,which can provide proof for the complex control system．
