| 摘 要： | 在故障诊断专家系统的基础上，引入粗糙集理论，并以信息系统属性值表为主要工具，对专家系统中的规则进行约简并剔除不必要的属性，揭示了故障诊断信号中内在的冗余性，降低了故障诊断专家系统构成的复杂性，并建立了简化后的决策规则。

| Abstract: | On the basis of fault diagnosis expert system,we introduce the rough set theory.Knowledge representation system table is taken as a major tool to reduce the rules of expert system and in which unnecessary properties are eliminated.The redundancy of fault diagnosis information is revealed.The complexity of fault diagnosis expert system's structure is also reduced.The decision-making rules are given finally. |
