摘    要:从民用飞机的经济性、环保性、舒适性和适应性出发,运用层次分析法建立多级层次结构,形成民机总体方案的综合竞争力评价模型。给出了民机方案各性能指标的量化方法,将设计准则转化为具体的民机性能指标。引入多人评价机制,提高评价模型各层级权重分布的合理性。应用本文方法对两种大型客机总体方案进行了综合评价,结果表明该方法能明确地识别出竞争力较高的设计方案,且评价结果具有合理性。算例表明该综合评价模型可用于民机总体方案的优选。

关 键 词:民用飞机  总体设计  综合评价  层次分析法  竞争力

Abstract:With the comprehensive consideration of economy, environmental pollution, comfort and flexibility of an aircraft, a mathematical model is developed to evaluate the conceptual design of commercial aircraft by analytic hierarchy process (AHP). Multi-criteria is transformed to specific technique data by a quantitative method. An approach for a group of experts to evaluate one target is introduced to improve the reasonability of weight distributions. The proposed method is used to evaluate two conceptual designs for the commercial aircraft. As a result, the better design is selected in a reasonable way. The example shows that the proposed method can be used to make decision when design selection is needed in conceptual design of commercial aircraft.
Keywords:commercial aircraft  conceptual design  comprehensive evaluation  analytic hierarchy process  competitiveness
