摘　　要：在民用飞机维修性设计中,维修性指标分配是一个重要环节。合理的分配维修性指标,可以使民机各系统在设计过程中省钱省力。在民机初步设计阶段,针对维修分配输入不足,首先利用层次分析法对维修性分配因素进行筛选,再运用模糊数学理论中的综合评判方法,综合考虑多方面的模糊因素,提出了基于设计特性模糊综合的维修性分配模型。最后,结合工程实例利用该方法对维修性指标进行了分配应用,结果表明该方法可用来指导民用飞机各系统的维修性设计工作,达到了维修性分配目的。Maintainability allocation is an important part of the aircraft maintainability design. Reasonable maintainability allocation can make the aircraft system design economically and effectivelly. In the preliminary design phase, the input of maintainability allocation was not sufficient. In this paper, analytic hierarchy process was used to select the factors of maintainability allocation. Then a maintainability allocation model based on fuzzy comprehensive evaluation was proposed, which included various characteristics of the aircraft design as evaluation factors. Finally, an example was analyzed in detail for the method mentioned above. The result shows that the model can be used to guide the aircraft system maintainability design and achieve the purpose of maintainability allocation.
