专家系统中的知识表示及其实时处理方法研究

The Research of Knowledge Representation and its Real-time Process in Expert System

文章以飞机驾驶员辅助决策系统为实例,建立并开发了一种面向对象的黑板模型,提出并实现了驾驶员辅助决策专家系统实例中知识的表示和实时知识处理的解决方案。该方案通过改善黑板模型的控制方式,提高了知识处理的并发性,同时引入消息管理器机制来实现对知识的实时处理。实际应用表明本方案比较适合于大型的知识系统的开发。

In this paper, through analysis of a Pilot Assistant (PA) system instance, an object-oriented blackboard model is constructed and developed. Its knowledge representation and real-time process is set forth and implemented. By improved the control manner of the blackboard model, this project increases the syndrome of the knowledge process. Additionally, introduce of Message Manager improves the real-time knowledge process. The application in this instance shows that the project adapts to large-scale knowledge system development.
