Keywords: multi-disciplinary and multi-objective optimization design, system decomposition, linear combined weighted object optimization method, simple genetic algorithm

In this paper, based on system decomposition approach, applying linear combined weighted object optimization method and simple genetic algorithm, a multi-disciplinary and multi-objective optimization method is built. As an example, an aerodynamic-stealth integration optimization design for a wing-body is carried out by using the method. Compared with original configuration, the aerodynamic and stealth performances of optimized configuration are improved.
