将灰色系统理论应用到飞机设计方案评价中,研究了一种含有方案评价指标体系和考虑评价指标权重以及灰关联分析的飞机方案优选灰色模糊聚类决策理论,这种决策理论利用指标权重将评价指标联系在一起,在评价方案与理想方案灰关联度的基础上进行灰色模糊聚类,实现方案优选.最后以一个短距/垂直起降(V/STOL)飞机设计实例证实此方法的科学性与可行性.
The gray system theory is applied to the evaluation of the aircraft design scheme. A gray fuzzy clustering decision theory is studied for the aircraft scheme with scheme evaluation index system and considering the weight of evaluation index and gray relational analysis. The decision theory uses the index weight to evaluate Indicators are linked together and gray fuzzy clustering is carried out based on the gray correlation between the evaluation scheme and the ideal scheme to realize the optimization of the scheme.Finally, a short / vertical takeoff and landing (V / STOL) aircraft design example is used to confirm the scientificity of this method With feasibility.
