Abstract:

An efficient simulation experimental design method is the basis for establishing high-fidelity response surface models, but the existing sequential experimental design is difficult to cope with the dilemma of dimensional explosion and relies on a single model characteristic, which is less general. Therefore, a sequential design method based on the local nonlinear approximations-intersite and projected distance (LOLA-DIST) criterion is proposed, which adaptively samples in the region with high nonlinearity and low distribution density, and better balances the global exploration and local development strategies, and is not dependent on the characteristics of the response model with good generality. Finally, the effectiveness of the proposed method is verified based on 7 types of functions. Experiment results show that the sequential design based on LOLA-DIST criterion has the highest computational efficiency compared with LOLA-Voronoi, Latin hypercube sampling design and stochastic design, which effectively reduces the sample size and the number of trials on the basis of ensuring the model prediction accuracy with better global optimization performance.

Key words: sequential experimental design, hybrid sampling criterion, local nonlinear approximations (LOLA), intersite and projected distance (INPD)
