Real time analysis on expert systems

In some comprehensive systems, as decisive loops, expert systems make up the whole system, so much more studies on reasoning time are necessary. The reasoning time in an expert system relates to its reasoning mode, its knowledge base architecture, the performance of the computer and the support languages. The paper takes the knowledge base architecture as an example to study the reasoning time. Finally, a temporally homogeneous Markov chain is used to model the knowledge base. The time estimating mathematics model and the computation method are also given, which can provide proofs for the comprehensive system control and real time simulation.
