基于相似体系的民机结构超手册维修案例分析
V267+.41; 为了解决超出手册范围的民机结构维修问题,提出一种基于相似体系的民机结构超手册维修案例体系模型.通过提取航空公司现有民机结构案例的损伤信息和维修方案信息,依据信息性质,采用数值分析、层次法、属性度量、术语频率-逆文档频率(term frequency-inverse document frequency,TF-IDF)方法进行系统的相似度分析,建立案例相似度指标体系.导入维修案例数据,通过支持向量机(support vector machine,SVM)分类以及弹性网络回归对指标体系进行权重分配并验证其可靠度达到82％.最后通过实例深度分析了该体系的可行性,实例证明,案例相似...
