Multi-Objective Reliability-Based Design Optimization utilizing an Adaptively Updated Surrogate Model
Original language description
The goal of this paper is to formulate a methodology for the multi-objective reliability-based design optimization (RBDO) that is applicable for any type of simulation model. The double-loop RBDO formulation seems to be the most robust approach for any kind of a nonlinear limit state function, in which the reliability assessment is nested in the inner cycle corresponding to the optimized variables designed in the outer cycle. The applied asymptotic sampling as an adaptive sampling method for reliabilityassessment seems to be a good compromise between the costs and accuracy. The computational demands can be decreased by using a meta-model instead of the simulation model. Since the design variables change with every iteration and the meta-model is utilized for the reliability assessment, the meta-model is trained only in the vicinity of the relevant design variable which makes the meta-model computationally faster and more precise. Samples from the asymptotic sampling located close to t
