渗碳专家系统中的多专家求解问题的研究

RESEARCH ON SOLVING PROBLEM BY MULTI-EXPERTS IN THE CARBURIZING EXPERT SYSTEM

本文研究了在渗碳专家系统中的问题求解策略,为了避免系统求解的主观性和片面性,提出了多黑板系统,例如,问题黑板、辩论择优黑板、领域黑板和结论黑板作为问题的求解策略,使其非公认的渗碳领域问题通过多专家进行辩论择优选出最佳解,为此提出建立基于多元组命题性知识的辩论理论框架,并体现不同策略的辩论算法,对此进行了计算机仿真,结果证明此方法是有效的。

The strategy of solving problem in carburizing expert system is studied in this paper. In order to advoid subjective view and one-sidedness, multi-blackboard strategy of solving problem is proposed, which are problem blackboard, domain blackboard, argument blackboard and conclusion blackboard. The best conclusions of non-acknowledged problem are selected through the argument of multiple experts. This paper builds a theoretical framework of argument on the basis of propositional knowledge. The argument algorithms is designed. The results of simulation are satisfactory.
