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 civil aeroengine maintenance effect can provide decision-making support for selection of aeroengine maintenance,repair and overhaul（MRO）company,and also help to find existing potential problems in aeroengine MRO company.To evaluate civil aeroengine maintenance effect,four principles on selecting evaluation indicators are proposed.Based on them,the aeroengine maintenance effect evaluation system is given,and then aeroengine maintenance effect evaluation model based on C2WH of Data Envelopment Analysis（DEA） is established.The modeling process of the model is also described.To solve the existing problem in selecting inputs and outputs of the decision-making unit,a solution based on indicator value transformation is proposed.Finally,a case study shows that the proposed method is effective.
