摘要
军机备件需求主要受到维修周转时间、重测合格率以及平均故障间隔等参数的影响,根据相关参数指标建立了多元回归模型,并应用最小二乘原理求出回归系数,检验了模型的可靠程度。通过一组实例数据得出备件需求量的经验公式,最后验证了该多元回归模型的有效性。
The service turnover time, resurvey percent of pass and mean downtime influences military aircraft spares demand, establish a multiple regression model basis the correlation parameters index, and then obtained regression modulus based on least squares principle and check its reliability. Finally, we got the empirical formula for spare calculating and verified the effectiveness through a group of dates.
