報告內容摘要：The accuracy, efficiency, stable results are major issues of the computational reliability methods. The performance-based accuracy and efficiency with robust searching scheme for determining the most probable point (MPP) is proposed by hybrid strategies given by first order reliability method (FORM) and hybrid support vector regression (SVR) coupled by population-based optimization method of global best particle swarm optimization (GPSO). The PSO and GPSO combined with SVR and also applied for MPP search are compared using traditional FORM iterative algorithms for accuracy, robustness and efficiency through several engineering problems.
