摘要
针对内燃机用于状态评估的特征参数指标体系缺乏相对客观的标准,研究以数据挖掘技术为基础的内燃机状态评估指标体系构建。基于粗糙集理论提出运用信息熵对内燃机的状态评估特征参数进行约简,进行了相应的算法设计与实现,建立了一个相对合理的内燃机状态评估指标体系。
objectivity As for the internal criterion, this pape combustion engine state evaluation characteristic index system without a relative r uses the data mining technique to solve the problem. Based on the rough set theory, using the entropy to eradicate the redundancy properties, the corresponding arithmetic has been de- signed and realized, a relatively reasonable IC engine state evaluation index system has been constructed.
