【摘要】 本文以锅炉常见故障为对象,通过分析锅炉故障的特点,提出了基于贝叶斯网络的专家系统。对贝叶斯网络理论进行了论述,分别研究了贝叶斯网络的基础理论及贝叶斯网络的网络推理方法。在专家系统的数据库设计中用面向事件的方法来表示浅知识,用面向对象的贝叶斯网络来表示锅炉故障中的不确定知识,在专家系统的推理机种引入了贝叶斯网络团树精确推理方法。建立了一个故障诊断专家系统,并用实例证明了系统在锅炉故障诊断中的有效性。更多还原

【Abstract】 By analyzing the failure of the characteristics of the boiler, this article considers boiler fault as the common object , then make a expert system based on Bayesian network. We have a discussion on Bayesian network theory, To study the basis of a Bayesian network theory and Bayesian inference methods network of networks. In the expert system database ,using Event-Oriented method to represent the shallow knowledge and using Object-Oriented Bayesian network to represent the knowledge of uncertainty of the failure of boiler, in the expert system inference engine, using Bayesian network group tree accurate method of reasoning. Building a fault diagnosis expert system ,using a example to proof the usefulness of this system in boiler fault diagnosis.更多还原
