摘要: 维修费用估算是无人机寿命周期费用估算的重要组成部分,维修费用是随着时间推移而递增的时间序列函数.针对传统估算方法,由于样本量有限而无法得到准确预测值的实际情况,引入灰色理论,运用GM(1,1)模型对某型无人机维修费用进行估算,预测出了一个较为准确的结果.灰色预测用于无人机维修费用估算效果较好.

Abstract: The estimate about the cost of repairing is important to the LCC(life cycle cost) estimate of unmanned air vehicle, which is time sequence function. The traditional method can not estimate the LCC accurately because the quantity of the samples is limited. The grey theory is introduced to estimate the cost of repairing about unmanned air vehicle by using the model GM(1,1) . The result of the estimation is quite accurate. This method is very effective to estimate the cost of repairing some unmanned air vehicle.
