决策树知识表示的多故障源搜索算法研究

在深入研究产生式规则知识表示的基础上,运用决策树知识表示方法,完成故障诊断专家系统的知识库设计,对传统的单故障源决策树搜索算法进行了改进,解决了相同故障现象的多故障源连续搜索和定位问题,提高了推理机单次故障诊断的定位率和搜索效率,缩短了故障诊断专家系统的诊断时间。

Algorithm of Searching Multi-Fault Sources Based on Decision-Making Tree Knowledge Expression

Based on the lucubrating of producing rule knowledge express,the decision-making tree knowledge express is used in the system to design knowledge database. Traditional single fault source decision-making tree search algorithm is improved,which solves the continued searching and orientation question on multi-fault sources of same fault phenomena. The fault diagnose orientated rate and searching efficiency are advanced,diagnosis time of fault diagnosis expert system is shortened.
