Abstract

Abstract

At present, the evaluation index for the demonstration program of civil aircraft operation requirement is not comprehensive and complete, and it is difficult to identify key indicators that affect the quality and competitiveness of civil aircraft products. On the basis of analyzing the operational environment and operational mission of civil aircraft, an index system of operational requirements for civil aircraft was established from six dimensions of aircraft adaptability, aircraft usability, equipment matching, maintenance rationality, aircraft advancement and dispatch reliability. The subjective weight and objective weight of the index were considered by the AHP-entropy method. The weight of each index was obtained, the membership degree of the index was determined by fuzzy set method, and fuzzy comprehensive evaluation matrix was constructed. A model for fuzzy evaluating the operational requirements of civil aircraft was proposed, an example of B737−800 was used to verify the rationality and feasibility of the evaluation model. The result shows that the model can reflect technical indicators of civil aircraft operation requirements and realize comprehensive evaluation of operational needs of civil aircraft.
