| 摘 要： | 贝叶斯网络(Bayesian Network)是近年来发展起来的一种基于概率理论的推理工具,本研究简要介绍了贝叶斯网络的基本理论,建立了电控发动机燃油供给系统故障信息的贝叶斯诊断网络,并利用Hugin Expert软件计算当燃油供给系统某一部件出现故障时不同故障现象出现的概率。研究表明,贝叶斯诊断网络能够有效诊断电控发动机燃油供给系统故障信息关联度。

| Abstract: | The Bayesian network is a reasoning tool based on probability theory,and it is developed quickly in recent years.This article discusses the basic theory of Bayesian network and constructs a Bayesian diagnostic network of the fuel supply system of the electronic engine,and use the software,hugin expert to calculate the probability of the appearance of different malfunction phenomenon.Its application helps us to draw a conclusion that Bayesian diagnostic network can diagnose the related degree of the fuel supply system of the electronic engine malfunction information effectively. |
