基于灰色关联的体系效能评估指标筛选

System Effectiveness Evaluation Index Screening Method Based on Grey Relation Analysis

针对体系效能样本量较少、样本数据规律不确定的特点,提出基于灰色关联的体系效能评估指标筛选方法。筛选方法利用序列曲线的几何形状相似程度判断评估指标与作战效能之间的关联度,通过关联度大小量化评估指标与作战效能之间的关联关系,筛选关键体系效能评估指标。将筛选方法应用于某导弹防御案例,验证了该方法的可行性。

A system effectiveness evaluation index screening method based on grey principal component analysis was proposed to solve the limited sample size and irregular sample distribution in system effectiveness evaluation.The geometric similarity of the serial curve evaluated the correlation of the evaluation index with combat effectiveness.The association between combat effectiveness and evaluation index was quantified by the correlation degree and screening key index in system effectiveness evaluation.This method can verify the feasibility of missile defence.
