The response surface method (RSM) is one of the main approaches for analyzing reliability problems with implicit performance functions. An improved adaptive RSM based on uniform design (UD) and double weighted regression (DWR) was presented. In the proposed method, the basic principle of the iteratively adaptive response surface method is applied. Uniform design is used to sample the fitting points. And a double weighted regression system considering the distances from the fitting points to the limit state surface and to the estimated design points is set to determine the coefficients of the r...

反应表面方法(RSM ) 是为与含蓄的性能函数分析可靠性问题的主要途径之一。改进适应 RSM 基于一致设计(UD ) 和两倍加权的回归(DWR ) 被介绍。在建议方法，反复地适应的反应表面方法的基本原则被使用。一致设计被用来取样恰当的点。并且就从试穿的距离而言的一个双加权的回归系统指向限制状态表面并且到点被设置决定反应表面模型的系数的估计的设计。与常规途径相比， UD 选择的恰当的点在关键区域是更多的代表，和更好的近似也与 DWR 被观察。数字例子证明建议方法有好会聚的能力和计算精确性。
