摘要
应用投影寻踪法,对保障性目标评估标准进行分析,利用在每个级别范围内随机产生的样本,建立了投影寻踪模型,确定了保障性目标评估指标的权重系数,得到了投影特征值变化区域与分类级别的对应关系,对某型航空装备使用初期的保障性试验数据进行分析,得到了其使用初期的级别和评估等级.为实现装备保障性评估目标评估拓展了新的途径,提供了科学依据.
Based on the analysis of supportability target evaluation standard and the sam- ples got randomly within the range of each class, projection pursuit model is set up with the projection pursuit method, which ascertains the weight coefficient of the supportability target evaluation index and yields the change range of projection characteristic value and the relationship between the classification grades. By analyzing the supportability experimental data of certain aerospace equipment during the initial stage of application, the initial stage application level and the evaluation grade are obtained. Thus, a new method is discovered and scientific basis is provided to assess the equipment supportability target value evaluation.
