Abstract: A reliability-based design optimization (RBDO) incorporates a probabilistic analysis with an optimization technique to find a best design within a reliable design space. However, the computational cost of an RBDO task is often expensive compared to a deterministic optimization, which is mainly due to the reliability analysis performed inside the optimization loop. Theoretically, the reliability of a given design point can be obtained through a multidimensional integration. Integration with multiple variables o… Show more

“…Thus, the RBDO problem was converted to a single loop deterministic optimization problem. In [60], authors have converted the multi-variable probabilistic constraint to a single-variable constraint using exponential polynomial coefficients, where the failure probability integral was evaluated by the mean of the adaptive Gauss-Kronrod quadrature. Thus, the RBDO problem was again converted to a deterministic optimization problem where the solution was computed using particle swarm optimization.…”
