A relative adequacy framework for multimodel management in multidisciplinary design optimization

Hierarchically constrained blackbox optimization

“…The search step is used to select points that minimize the error induced by low cost models within a trust region. This framework expands the use of MADS to multi-disciplinary design optimization [16] and time-dependent multidisciplinary design optimization [17].…”

Supporting the Engineering of Multi-Fidelity Simulation Units With Simulation Goals

“…Several research works using multi-fidelity modelling have been reported in the literature [7], [8], [17]- [19]. Typically these works focus on how to select a model with the desired accuracy that is less computational and time demanding to simulate [20].…”

“…Typically these works focus on how to select a model with the desired accuracy that is less computational and time demanding to simulate [20]. In [7], [8], [17], multiple models with different fidelity levels are used during a simulation for simulation speed up. A region of interest is defined where the use of a highfidelity model is required to keep the simulation error at a low level.…”
