中文摘要：
结合sequential和successful的响应面方法以及Kriging插值技术，针对高维优化问题，建立一种混合响应面优化方法。首先采用sequential响应面方法基于初始化变量进行优化，采用Kriging插值方法对样本点和优化过程中形成的优化点重新进行响应面构造，以确定优化范围内新的初始值并将约束减小到一定范围；随后采用successful响应面对更新的设计变量初始值和约束范围进行优化。如此循环，直至得到最优解。采用该方法对汽车前纵梁中板的厚度问题进行优化，取得了不错的效果。
英文摘要：
A new mixed response surface method combined with sequential response surface method, successful response method and Kriging interpolation method was proposed for high dimensional problems. The sequential response surface was employed for producing coarsen response surface. And then, the Kriging interpolation method was used for constructing the better robust surface to decide the better initial values of design variable and reduce constraints to in considerable range. Finally, the successful response surface was applied for finding the best optimization result, The shell thickness of front side member of auto was optimized by suggested method and got better result.
