...-cost statistical regression models instead of assuming certain values, such as zero. A regression model, given the existing data, is used as a proxy surrogate model for each expensive black-box utopia optimization. The estimation of utopia values, rather than assuming values, increases the accuracy...

...Yongsu Jung; Kyeonghwan Kang; Hyunkyoo Cho; Ikjin Lee Even though many efforts have been devoted to effective strategies to build accurate surrogate models, surrogate model uncertainty is inevitable due to a limited number of available simulation samples. Therefore, the surrogate model uncertainty...

... model of simulations of multistage assembly processes. At the heart of this approach is a multiple-input-multiple-output surrogate modeling framework that uses a recently developed integrated emulation technique. The unique feature of this technique is that the surrogate models for multiple outputs...

..., and surrogate models to arrive at robust designs on a limited computational budget. The multiobjective formulation used here allows explicit trade-off between the mean and variance of the performance to be carried out. Detailed numerical studies are presented for robust geometric design of a typical compressor...
