摘要
在网络故障诊断系统中,可以用粗糙集理论约简网络信息M IB变量,从而求出最有利于分类的变量集合。提出了首先约简信息表,并构造多变量决策树,提取相应的决策规则,判断网络故障类型的方法。决策树构造方法简单,提取出来的规则以决策树形式表示,规则易于理解,网络故障诊断效率较高。
In the networks diagnosis system,the reduced networks information MIB varied quantity of rough set theory can be used,so as to get the varied set which is most advantageous to classifying.This paper puts forward the reduced information table,so as to form multi-varied quantity decision tree,takes relative decision rule,and judge the networks faults type.The decision tree is simple for its forming method.The rules fetched shows as decision tree,which is easy to understand.The diagnosis rate of the networks faults is high.
