Robust Engineering Design by Stochastic Optimization

According to the affecting factors on the quality in products, the criterias for quality design and the robustness of design solution are disscussed and a new approach for the robust optimal design is investigated make use of principle for stochastic modeling. This method is defferentiated a general methods of robust design by that obtain the solution bring pass simultaneity to adjust the design variables and to control its tolerance. The evaluating results show that is a effective method.
