摘　　要：针对常规灰色关联分析方法主要依据序列曲线几何形态的相似程度进行关联判断,将常规灰色关联理论直接应用于模型验证中存在一定风险的问题,提出了比商灰色关联度模型验证的方法。该方法使用比商形式进行参考序列和行为序列数值比较,避免了常规灰色关联系数因绝对值运算无法敏感位移差正负性的缺陷,提高了灰色关联分析的可靠性,为客观有效地进行模型验证奠定了基础。仿真和实例分析表明比商灰色关联度模型方法的有效性和实用性。To reduce the risk of validation of simulation models based on ordinary gray relational analysis（GRA）,we proposed a new model named division gray relational analysis model（DGA）to satisfy the special need of validation of simulation models.The new division gray relational analysis model used the form of division to compare the simulation series and the flight-test time series,so that it could avoid the drawback of not being sensitive to plus-minusof displacement.By dong so,it could improve the reliability of gray relational analysis to have a higher accuracy of validation of simulation models.Finally,case study was given to show the reasonability and validity of the improved model.
