基于随机优化的工程稳健设计

Robust Engineering Design by Stochastic Optimization

根据影响产品质量的因素，讨论了质量设计的准则和设计解的稳健性，并利用随机建模原理提出一种工程稳健设计的新方法．该方法与一般稳健设计不同的是，通过同时调整设计参数与控制其容差来达到稳健设计的最优解．数值分析表明，该方法是十分有效的．

According to the affecting factors on the quality in products， the criterias for qualitydesign 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 toadjust the design variables and to control its tolerance. The evaluating results show that is a effective method.
