“…18 In the reliability-based design optimization approach, uncertainties affect only the design constraints, which are written in such a way as to warrant a minimal level of safety for the optimal design. 19,20 In the robust design optimization approach, one can consider uncertainties in both the objective and constraints. 21 The objective is changed into a weighted sum between the expectation and standard deviation of performance, while the constraints are given as a weighted sum between mean and standard deviation of the constraint variable.…”

“…The optimization procedure may require a high computational cost [4]. For this reason, several authors have studied methods that use single loop RBDO [3,[5][6][7]. These authors have applied reliability-based design optimization strategies like SAP (Sequential Approximate Programming) and SORA (Sequential Optimization and Reliability Assessment), which are capable of solving the majority of practical cases, when multiple modes of failure are present, but for linear and smooth functions.…”
