The book explores Kriging metamodeling for interpolation, sensitivity analysis and optimization of simulation models with costly computational expenses. A novel Kriging model is developed and named Taylor Kriging (TK) where Taylor expansion is used to identify a drift function. Taylor expansion has the excellent nonlinear approximation capability, thus enhancing the interpolation capability of Kriging. Sample standard deviation is used as the metric for influence distance in a covariance function of Kriging, and makes simulations with data of differing magnitudes have a consistent measure unit. The partial differentiation equation of Kriging is developed and used together with analysis of variance to assist in sensitivity analysis on a simulation model. A novel simulation optimization algorithm named SOAKEA is created which integrates Kriging with evolutionary algorithms to optimize simulation models with expensive running cost. The properties of SOAKEA are investigated, and some...
