Multi-Objective Reliability-Based Design Optimization using Subset Simulation Enhanced by Meta-Models

Original language description

This paper deals with double-looped reliability-based design optimization, where the reduction of the computational effort is made by utilizing subset simulation using local meta-models, namely radial basis function model, that are assembled from an adaptively updated Design of Experiment (DoE). Since the optimized design variables change with every optimization iteration and a meta-model is utilized for a 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. DoE is updated by selected points from subset simulation samples with respect to two criteria: first, beneficial samples are located in the vicinity of the limit state, second, these samples should also be placed in the sparsest position of the DoE.
