| 摘 要： | 分析了在操作票专家系统中普遍采用的产生式规则的局限性,指出推理程序对规则表示的依赖性是制约操作票专家系统通用性的根本原因。针对上述问题,首先研究了将产生式规则转化为Petri网模型的方法,提高规则表示的灵活性;其次,研究了基于Petri网模型的推理方法,使推理程序与规则表示完全分离,提高推理的灵活性。文章结尾得出结论并对进一步的研究进行了展望。

| Abstract: | This paper analyses the disadvantage of production knowledge representation which has been widely used in order-sheet expert system,and indicates that dependent relation between inference program and rules is the main reason which restricts the adaptability of order-sheet expert system.To solve the above problem,firstly,this paper establishes a model of production knowledge based on Petri net;secondly,a new inference engine is brought forward,which can separate inference program from knowledge representation and improve flexibility of inference.Finally,a conclusion is drawn and some questions for further research are brought forward. |
