Title: Sequential Latin hypercube design for two-layer computer simulators
Authors: Yan Wang - Beijing university of technology (China) [presenting]
Abstract: The two-layer computer simulators are commonly used to mimic multi-physics phenomena or systems. Usually, the outputs of the first-layer simulator (also called the inner simulator) are partial inputs of the second-layer simulator (also called the outer simulator). How to design experiments by simultaneously considering the space-filling properties of inner and outer simulators is a significant challenge that has received scant attention in the literature. To address this problem, a new sequential optimal Latin hypercube design (LHD) is proposed by using the maximin integrating mixed distance criterion. A corresponding sequential algorithm for efficiently generating such designs has also been developed. Numerical simulation results show that the new method can effectively improve the space-filling property of the outer computer inputs. The case study about composite structures assembly simulation demonstrates that the proposed method can outperform the benchmark methods.
