摘要:Kriging代理模型通过对某预测点周围的信息加权的线性组合来预估该点的未知信息,因其加权选择由最小化预估值的误差方差来确定而被视为最优的线性无偏估计。本文研究Kriging代理模型的序列优化,提出了一种新的加点规则—DH最大点插值法,并利用遗传算法的全局搜索能力搜索模型迭代的插值点,进而提高了Kriging模型的建模精度。
Kriging surrogate model predicted the unknown information of a point by a weighted linear combination of information around the point. Kriging surrogate model was considered to be the best linear unbiased estimator for its weighting selected by minimizing the estimated value of the error variance. This paper studied sequential optimization method for the kriging surrogate model, and then proposed a new rule for pulsing points-maximizing the value of DH. Finally, we improved modeling accuracy of kriging model by using genetic algorithms to find the model iterative interpolation points
