民机DMC预测模型的修正研究
首发时间:2015-06-12
摘要:传统的DMC预测模型由于其提出年限过长、民用飞机设计技术及思路的发展等因素,其精度已经不能满足现代飞机的要求。本文首先从CPI指数、维修效率、维修人工时费率、送修率、飞机老龄化等方面考虑,对传统DMC预测模型进行修正;然后,运用相关数据的计算,检验修正模型的精度;并对不同的DMC模型的修正效果进行对比。最后,对DMC预测模型的修正思路进行了总结和展望。

Correction of DMC prediction model for civil aircraft
Abstract:Due to the long time it has been built, the development of the aircraft design technology and other factors, the precision of the traditional DMC prediction model can't meet the requirement of the modern aircraft. Firstly, the model is corrected with the following aspects, such as CPI, maintenance efficiency, labor cost of maintenance, ratio of outsourcing maintenance, aircraft aging. Secondly, tests the precision of the advanced models with the relative data, and then compare the precision of them. Finally, a correction method of the DMC prediction model is made.
Keywords: aircraft design civil aircraft direct maintenance model correction
