军用飞机维修保障费用的GM(1,1)预测

Estimating with Grey Method for Military aircraft's Maintenance Cost

针对传统费用估算方法样本需求量大,实现繁琐的缺点,本文引入灰色理论,建立了某型机维修保障费用灰色GM(1,1)预测模型,并进行了精度检验,结果表明所建立的模型准确、有效。最后利用建立的模型对该型机一个飞行中队未来几年的维修保障费用进行了预测。

For the large quantity of sample and the cockamamie fulfilling of the traditional cost estimating method,the grey method is applied to the maintenance cost estimating.the grey estimate model GM（1,1） of a certain type airplane ＇s maintenance cost is established.And the precision verification is carried out,which shows that the established model is accurate and available.Finally,using the model the next years＇ maintenance cost of a flight brigade planes is estimated.
