Civil Aircraft Supplier Selection Based on Reliability,Maintainability and Testability

Abstract

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, a method for selecting civil aircraft suppliers based on the three indicators is proposed.Firstly, the classification of civil aircraft suppliers is introduced.Secondly, the selection criteria considering different types of civil aircraft suppliers is 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 are obtained.The results show that the proposed method can provide different selection views for supplier of civil aircraft, satisfy the requirement of supplier selection demand under the design concept of civil aircraft.
