提出了飞行器系统效能评估的改进模糊综合评判模型,采用模糊定权法,根据相对隶属度确定因素权重,并依据最大隶属度原则做出决策,提高评判方法的客观性和准确性,克服了经验定权的模糊方法存在主观性较强的不足。将改进的模糊综合评判模型用于对飞行器系统设计方案进行量化评判和筛选,分别对6种复合材料机翼结构效能、2种无人机和3种巡航导弹的隐身和气动效能进行了评估;并将结果与灰关联模型的评判结果对比,验证了模型的有效性,得到了对工程设计具有参考价值的结论。
An improved fuzzy comprehensive evaluation model of aircraft system effectiveness evaluation is proposed. Fuzzy weighting method is adopted to determine the weight of factors according to the relative membership degree, and the decision is made according to the principle of maximum membership degree so as to improve the objectivity and accuracy of the evaluation method and overcome the experience There is a subjectivity weakness in the fuzzy method of the right of fixing. The improved fuzzy comprehensive evaluation model is used to quantitatively evaluate and screen the design of the aircraft system. Six composite aeromechanical wings, two UAVs and three cruise missiles are evaluated for stealth and aerodynamic performance. The results are compared with those of the gray relational model to validate the validity of the model, and the conclusion is reached that it has a reference value for engineering design.
