摘要
本文将贝叶斯网络引入到大型网络故障管理系统中,从贝叶斯网络推理模型与故障诊断和维修决策问题的一致性出发,提出了基于故障假设、观测和维修操作节点结构的DBN模型,并详细阐述了模型的内涵和故障诊断知识构成要素。
This paper applies the Bayesian Network (BN) to large network management systems. By studying the consistency of the BN inference model, network fault diagnosis and maintenance decision, we propose a Diagnostic Bayesian Networks (DBN) model which consists of fault hypothesis nodes, observation nodes and maintenance nodes. Mathematical description and knowledge inseapes of DBN are given.
