This paper aims to develop a new Response Surface Methodology (RSM)-XU-RSM-adapted to Reliability-Based Design Optimization (RBDO) based on Diffuse Approximation (DA) and First-Order Reliability Method (FORM). The essential of the new response surface methodology is to use simultaneously the points both in a design space (X-space) and an independent standard normal random space (U-space). Mixing the points allows for more precise local approximation due to denser sampling points and leads to a faster convergence. Finally, a mathematic example is given to show how to use the new method and the comparison of results of evolutions.
