Fuzzy optimization of geometrical parameters of fighter basing on fluctuating weights

Based on the theory and formula of fluctuating weights proposed by Wang, the character of the fluctuating weights and the comprehensive evaluation function of the fluctuating weights and the difference between the fluctuating weights and constant weights are discussed. And then the fluctuating weights are used in the integrated aerodynamic-stealth design of geometrical parameters of fighter. The results of the optimization using fluctuating weights and constant weights are discussed respectively. The results show that the optimized method using fluctuating weights is better than that using constant weights.
