基于改进AHP方法的飞机修理级别经济性分析

摘要

Level of repair analysis (LORA) plays a significant role in support analysis of equipment, and it is the most effective during the project development stage. LORA existing domestic model is mainly on non -economic analysis and it is less related to economic analysis, the latter often require large amounts of data and computer simulations, whereas it is lack of relevant data in aircraft development. Based on this,integrating analytic hierarchy process (AHP) and Grey relational analysis for repair level analysis of economic decision -making methods is presented, which can be judged preliminarily for repair level analysis of economic decision in the absence of data. Finally, comparative analysis by example illustrates the correctness of the method.%修理级别分析(LORA)是飞机保障性分析的一个重要内容,在工程研制期间进行分析最有效.国内现有的LORA模型主要是关于非经济性分析,较少涉及经济性分析,后者往往需要大量数据及计算机模拟,而在飞机研制中又缺乏相关数据.基于此,提出了用层次分析法(AHP)和灰色关联分析进行修理级别经济性分析决策方法,可在缺乏数据时对修理级别经济性作初步判断.最后通过实例对比分析说明了该方法的正确性.
