两级修理模式下民机修理级别非经济性分析研究

摘要

Aiming at two-level maintenance mode in aircraft maintenance planning gradually be taken seriously,it is proposed that the level of repair analysis non-economic evaluation for aircraft maintenance based on two-level maintenance. Based on the standards of GJB- 2961-1997,two-level of repair analysis index system has been established. On this basis,the fuzzy analytic hierarchy process is used to determine the weight coefficient of each evaluation index,and the grey relational’degree has been got with weighted grey relational coefficient. Finally,the aircraft repair level comprehensive evaluation has been realized based on fuzzy analytic hierarchy process and grey relational analysis methods. At last,the instance analysis has been used to verify the rationality and validity of the proposed model.%针对两级修理模式在飞机维修规划中得到逐步重视的问题，提出了两级修理模式下民机修理级别非经济性分析模型。其中基于GJB-2961-1997标准，建立了两级修理级别分析的指标体系，在此基础上，利用模糊层次分析法确定各评价指标的权系数，并对灰色关联系数加权得到灰色关联度，实现了基于模糊层次分析法和灰色关联分析法的飞机修理级别综合评估。最后通过实例分析，验证了所提模型的合理性和有效性。
