The method provides a better accuracy for the assessment and the optimal selection of the water consumption forecasting models. The results show that the forecasting model built on this comprehensive assessing method presents better self-adaptability and accuracy in forecasting.展开更多
PHM(Prognostic and Health Management)是装备实现自主保障的一项关键技术。通过对美军联合攻击机PHM系统功能和结构的分析,提出了一种基于扩展FMEA的PHM系统的实现方法,并阐明了其运作原理。在此基础上,引入模糊综合评判这一数学方法...PHM(Prognostic and Health Management)是装备实现自主保障的一项关键技术。通过对美军联合攻击机PHM系统功能和结构的分析,提出了一种基于扩展FMEA的PHM系统的实现方法,并阐明了其运作原理。在此基础上,引入模糊综合评判这一数学方法建立了PHM系统的故障预测模型。最后以飞机起落架的收放系统为例进行了实例分析。展开更多
