| Abstract: | For solving the problem of long calculation time when high accuracy simulation model was used in MDO analysis in complex systems,Gaussian Process Surrogate mode was proposed.Gaussian Process surrogate model theory was proposed,and its flow chart was analyzed in detail.Through example analysis,Gaussian Process surrogate model was proven better than anther two existing surrogate models.It shows that local surrogate models are special cases of Gaussian Process Surrogate mode,which will be the focus of investig... |
