对民航发动机维修效果进行评价可以为发动机承修厂的选择提供决策支持,同时有助于发现发动机承修厂的潜在问题。为了实现发动机维修效果的评价,首先提出了评价指标选择的原则,在此基础上给出了发动机维修效果评价指标体系,建立了基于数据包络分析的C2WH模型的发动机维修效果评价模型,并对模型的构建过程进行了描述。针对决策单元输入输出选择存在的问题,提出了基于指标值变换的解决方法。最后,通过应用案例验证了所提方法的有效性。
Evaluating the effectiveness of civil aviation engine repair can provide decision support for the selection of engine repair shops and help identify potential problems with engine repair shops. In order to evaluate the effect of engine maintenance, the principle of selection of evaluation index is first proposed. Based on this, the evaluation index system of engine maintenance effect is given, and the evaluation model of engine maintenance effect of C2WH model based on data envelopment analysis is established. The construction of the model is described. Aiming at the existing problems of input and output of decision-making unit, a solution based on index value transformation is proposed. Finally, the validity of the proposed method is verified through application cases.
