摘要
降低民用飞机直接维修成本是提高飞机经济性、增强市场竞争力的重要途径。以民用飞机研制阶段在很大程度上决定其维修成本的高低为背景,在分析相关文献研究成果的基础上,构建可反映民用飞机成本特性的设计参数结构层次图,基于TOPSIS-灰色关联法计算类似机型的相对相似度,进行民用飞机直接维修成本分配;将类似机型典型系统直接维修成本数据输入分配模型进行验证。结果表明:本文模型可较为准确地预测民用飞机系统级直接维修成本,计算结果满足工程要求,可为预测新研机型直接维修成本提供参考。
In order to reduce direct maintenance costs of civil aircraft,it is an important way to improve aircraft economics and enhance market competitiveness.Based on the background that the maintenance cost is largely determined in the development stage of civil aircraft,a hierarchical diagram of the design parameter structure that reflects the cost characteristics of civil aircraft is constructed.The TOPSIS-grey correlation method model is established to calculate the relative similarity of similar aircraft and to carry out the direct maintenance cost allocation of civil aircraft.The direct maintenance cost data of typical systems of similar aircraft types is input into the allocation model for verification.The results show that the model can predict the system-level direct maintenance cost of civil aircraft well,and the calculation results can meet the engineering requirements.The method can provide a reference for predicting the direct maintenance cost of the newly developed aircraft.
