摘要
根据Petri网能够对知识的细节进行抽象的特点及对知识库系统应用的需求,利用VC++对Petri网进行了类的封装,建立了基于面向对象Petri网的知识库模型,实现了对知识库的动态维护,并增加了单步推理和反向执行的功能,同时也改进了规则维护算法。
According to the capability of petri net abstracting the detail of knowledge and requirement of applications of knowledge-base system, class of petri net is packed by using VC++, and a knowledge-base model based on object-oriented petri net was established. The dynamic maintenance of knowledge base was implemented. The functions of reasoning step by step and reverse operating were added, and the algorithm of rule maintenance was improved
