... sampling methods for creating Kriging surrogate models in seven numerical cases and one real-world engineering case of a cutterhead of a tunnel boring machine. The results show that compared with the other four methods, the proposed sequential sampling method can more quickly and robustly create...

.... The proposed STRA method aims to improve the efficiency of constructing the kriging model by sampling in the regions with large failure probability prediction errors and shifts the adaptive sampling domain from the global space to the vicinity of the LSF. Two major issues need to be addressed: (1) properly...

... manner. In this paper, a multi-objective infilling strategy integrating the Kriging model with a two-stage infilling framework is proposed, termed as ATKIS. This method allows exploitation and exploration alternately to pinpoint the infilling solution for improving the Pareto set and avoiding local over...

...Tianzeng Tao; Guozhong Zhao; Shanhong Ren To solve challenging optimization problems with time-consuming objective and constraints, a novel efficient Kriging-based constrained optimization (EKCO) algorithm is proposed in this paper. The EKCO mainly consists of three sampling phases. In phase I...
