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。
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 commer cialaircraft 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 desi gns 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.
