基于AHP?熵权法的民用飞机运行需求模糊综合评价

目前用于民用飞机运行需求论证方案的评价指标不够全面完整，难以找出影响飞机产品质量和竞争力的关键指标. 在分析民用飞机运行环境和运行任务基础上，从机型适应性、飞机使用性、设备匹配性、维修合理性、飞机先进性、签派可靠性等6个维度建立民用飞机运行需求指标体系，应用AHP?熵权法综合考虑指标的主观权重与客观权重，得出各指标综合权重；采用模糊集方法确定指标的隶属度，构建模糊综合评价矩阵；提出民用飞机运行需求模糊综合评价模型，通过B737?800机型实例验证该模型的合理性和方法的可行性. 结果表明，该模型反映了民用飞机运行需求的技术指标，实现对民用飞机运行需求的综合评价.

Fuzzy comprehensive evaluation of civil aircraft operational requirement based on AHP-entropy method

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.
