Cokriging模型
WebJul 20, 2024 · Design and optimization of morphing wings are of current research interest as they promise increasing efficiency and flexibility of future aircraft. A challenging task is to find structural layouts of morphing wings that enable aerodynamically optimized shape changes without defining the target shape a priori. The current paper addresses this task and … WebOct 27, 2024 · The third type is the Cokriging model, which originated in the geostatistics community [20], [21]. Kennedy and O’Hagan [22] generalized the Cokriging approach to computer experiments, which is known as KOH autoregressive model. Thereafter, the Cokriging model has gained popularity in different fields due to its good performance.

WebThe cokriging estimator is written as: The corresponding cokriging system requires knowledge of only the Z covariance C Z ( h) and the Z − Y cross-covariance C Z Y ( h). The latter can be approximated through the following model: where B = C Y ( 0) / C Z ( 0) ⋅ ρ Z Y ( 0), C Z ( 0), C Y ( 0) are the variances of Z and Y, and ρ Z Y ( 0) is ...
