Abstract :
The basic ant optimization algorithm is improved by introducing ant colony scatterance and discrete search. In order to solve the optimization problem with mixed-discrete variables, a program of ant algorithm is designed by using MATLAB. Based on the introduce of support vector regression (SVR) which is used to compute the values of nonlinear functions such as fuzzy probability, the computational efficiency of robust design optimization is distinctly improved. An example of robust design optimization with mixed-discrete variables is presented, and it shows that the proposed method is effective in engineering application.
