摘要
为了科学合理地制定民航发动机的维修工作范围,提出一种面向全寿命周期的基于性能状态的发动机送修目标确定方法。研究了发动机性能衰退模型及性能恢复值与维修成本之间的关系。建立了面向全寿命周期的基于性能状态的送修多目标优化模型,并提出了模型求解方法。采用某航空公司的实际数据对提出的方法进行了验证。结果表明提出的方法是有效的,能够为发动机送修目标的确定提供决策支持,避免了送修目标确定的随意性。
To make a scientific and reasonable maintenance workscope of civil aero-engine, an approach for aero-en gine repair objective determination which was oriented to the life cycle based on performance state was proposed. The performance deterioration model and the relationship between the performance recovery and maintenance cost were studied. A multi-objective optimization model for repair objective oriented to the life cycle based on perfornl ance state was established, and its solution method was put forward. The approach was validated by the actual data from an airline. The results showed that the proposed approach could provide decision support for aero-engine repair objective determination and avoid the randomness of making repair objective. The effectiveness of this approach was also proved.
