摘　　要：针对民机维修工程分析中修理级别分析(level of repair analysis,LORA)的研究,在民机维修保障体制特点的基础上综合考虑经济性和非经济性两个因素,对各类影响民机修理级别的评价因素进行综合分析。应用可拓层次分析法(extension analytic hierarchy process,EAHP)与模糊综合评价法(fuzzy comprehensive evaluation,FCE)建立了一种民机修理级别综合评价模型,并采用灰色关联分析法对比验证了模糊评估结果。在模型求解中,利用区间数取代点的值构建判断矩阵,求解各层次指标权重,采用模糊综合评价法求得模糊关系;将指标权重与模糊评估矩阵进行线性结合以求解复杂的多因子包容方程,归一确定最优方案;通过关联系数分析法对比验证可行性方案与理想方案的关联度。通过实例对提出的模型进行了验证,结果表明方案V3为最佳方案,即修理级别为基地级,与工程文件中的指导基本一致,说明该模型有效可行。所建立的民机修理级别确定模型完善了修理级别分析理论,能够为航空制造商和航空公司在飞机设计和使用阶段对飞机修理级别确定提供参考。In view of the research on the level of repair analysis(LORA) in the analysis of civil aircraft maintenance engineering, the economic and non-economic factors are comprehensively considered on the basis of the characteristics of the civil aircraft maintenance guarantee system, and the comprehensive analysis of various evaluation factors affecting the civil aircraft level of repair is carried out. A comprehensive evaluation model for civil aircraft level of repair was established by using the extension analytic hierarchy process(EAHP) and the fuzzy comprehensive evaluation(FCE), and the fuzzy evaluation results were verified by the grey correlation analysis. In the process of model solving, the model used interval number instead of point value to construct the judgment matrix and solved the weights of index at all levels, and the fuzzy comprehensive evaluation method was used to obtain the fuzzy relationship. The index weight and the fuzzy evaluation matrix were linearly combined to solve the complex multi-factor inclusion equation, and the optimal scheme was determined by normalization.The grey correlation analysis method was used to verify the correlation between the feasible scheme and the ideal scheme. The proposed model was validated by an example, and the results indicated that the best scheme was V3, that was, the level of repair was base level, which was basically consistent with the guidance in engineering documents and showed that the validity of the model. The established model for determining civil aircraft level of repair analysis improves the theory of level of repair analysis, which can provide reference for aircraft manufacturers and airlines to determine the repair level of aircraft in the design and use phase.
