Abstract

Abstract: To solve the prevision，timing and rationality of equipment maintenance for industry system maintenance，proposes the model on industry system maintenance based on Bayesian networks.The model of system maintenance is analyzed and gives a particular description.To utilize the superiority of Bayesian networks solving uncertainty to the problem deduced，analyzed and located that is better effect.A practical example verifies that Bayesian networks model has effective direction for maintenance decision and maintenance implementation of industry system.

Key words: Bayesian networks, preventive maintenance, fault source tracing, prior probability, posterior probability

摘要： 为解决工业系统维护中的设备维护的预知性、适时性和合理性等问题，提出一种基于贝叶斯网络的工业系统维护模型。详细分析并介绍了建立系统维护模型的过程，利用贝叶斯网络解决不确定性问题的优势对问题推理、分析与定位，效果较好。通过应用示例，证明贝叶斯网络模型对工业系统维护实施，维护决策具有有效的指导作用。
