基于可靠性、维修性和测试性的民用飞机供应商选择

民用飞机的研制需要供应商的协同和支持，因此民用飞机供应商的选择至关重要。为满足民用飞机着重于可靠性、维修性和测试性的设计理念，提出基于可靠性、维修性和测试性的民用飞机供应商选择方法。首先介绍民用飞机供应商的分类；其次建立基于不同类型民用飞机供应商的选择准则，并基于选择准则列举相对应的下属指标；最后采用层次分析法，建立氧气系统供应商的选择模型并模拟专家打分，得出不同供应商各准则和指标的权重，根据评分选择最优供应商。结果表明：该方法能够为民用飞机供应商的选择提供不同选择视角，满足现代民用飞机设计理念下对供应商选择的需求。

Civil Aircraft Supplier Selection Based on Reliability,Maintainability And Testability

The development of civil aircraft requires the collaboration and support of suppliers, so the choice of civil aircraft supplier is crucial. In order to meet the design concept of modern civil aircraft that emphasizes reliability, maintainability and testability, the article proposes a method for selecting civil aircraft suppliers based on the three indicators.. Firstly, the classification of civil aircraft suppliers is introduced. Secondly, the selection criteria considering different types of civil aircraft suppliers are established, and the subordinate indicators corresponding to each criteria are listed. Finally, the Analytic Hierarchy Process method is selected to establish the selection model of the oxygen system suppliers as well as make expert score simulation, and the importance of the indicators and criteria of different suppliers were obtained. On this basis, the supplier with better performance is selected,thus providing a reference for the selection of civil aircraft suppliers considering reliability,maintenance and testability indicators.
