【摘要】 根据电脑故障知识结构性差、耦合性不强及特征参数不易提取的特点,采用适合该问题的模糊产生式算法进行故障诊断推理,设计了故障知识的三层模型、表达方法和知识库结构,给出了基于模糊区间的语义距离计算公式、基于故障树的防止规则组合爆炸的规则分组方法和带误差控制的阈值选取方法,运用面向对象的理论设计和实现了电脑故障智能诊断系统,其中描述了B/S模式下分布式计算环境的系统结构和规则类的设计。更多还原

【Abstract】 According to the computer faults’ characters with worse structure,not strong coupling and not easily distilling the characteristic parameters,the fuzzy production rule inference is used to diagnose the computer fault.The three-layer model and expression method of faults knowledge and structure of knowledge repository are designed,including the method of computing fuzzy distance,the method of rule group based on fault tree avoiding the rules combination blast,and the way of selecting threshold with error control.The whole intelligent diagnosis system of computer faults is designed and realized by using the objectedoriented theory.At last,the distributing system structure of B/S mode and the design of rule class are described.更多还原
