摘　　要：针对民机修理级别分析(LORA)经济性分析模型较少,且存在数据缺失,可信度较差等问题,提出了基于模糊层次分析法(FAHP)的修理级别经济性分析模型;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民机修理级别经济性分析综合评估;最后通过实例分析,验证了所提模型的合理性和有效性。Aiming at the problems that there is little economic evaluation model for the civil aircraft’s level of repair analysis,the existing data is missing seriously and the data is hard to convince,a level of repair analysis economic evaluation model based on fuzzy analytic hierarchy process has been put forward.On this basis,the fuzzy analytic hierarchy process was used to determine the weight coefficient of each evalua-tion index,and the grey relational’degree had 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 ra-tionality and validity of the proposed model.
