Fuzzy Optimization of Geometrical Parameters of Fighter Basing on Fluctuating Weights

Basing on the theory and formula of fluctuating weights given by Prof. Wang Peizhuang, 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 optimizations using fluctuating weights and constant weights respectively are discussed. The results show that the optimizations method using fluctuating weights is better than that using constant weights.
