作战飞机总体设计方案的灰色关联投影评价

Conceptual Design Scheme Evaluation with Grey Relation Projection for Combat Aircraft

给出了作战飞机总体设计方案的评价指标,采用层次分析法赋给每个指标不同的权重,并提出了一种基于灰色关联投影法的作战飞机总体设计方案评价方法。该方法采用灰色关联理论建立各总体设计方案对评价指标集的加权灰色关联判断矩阵,然后利用矢量投影原理计算各设计方案相对理想方案的灰色关联投影值,以灰色关联投影值的大小来评价设计方案的优劣。

Evaluation indexes of the conceptual design scheme for combat aircraft are analyzed, the weight coefficients of every evaluation index are determined with the Analytic Hierarchy Process, and a conceptual design scheme evaluation method for combat aircraft based on the Grey Relation Projection method is proposed. The method builds a weighted grey relation matrix of the evaluation indexes for aircraft conceptual design schemes with grey relation theory, then calculates grey relation projection values of the design schemes on the perfect scheme by vector projection theory, the design schemes can be evaluated by the grey relation projection values.
