Metamodeling is generally recognized efficient approach for the optimization problems. In our case it is used for shape optimization. Due to development of CAD/CAE software and advanced metamodeling techniques such approach has become highly effective and popular in recent years. The references to the non parametric approximation methods are commonly given to solve deterministic problems. For non-deterministic optimization problems, such as in proposed case of composite pallet structure (Figure 1) that must account for uncertainties, the optimization should be based on double loop approaches where the uncertainty propagation is recursively performed inside the optimization iterations. Often the uncertainty estimation for the given point is based on metamodel, thus allowing reduction of computational time but introducing additional bias in the estimates. In such approach a single loop kriging based method for minimizing the mean of an objective function is proposed: the simulation points are calculated in order to simultaneously propagate uncertainties, i.e., estimate the mean of objective function, and optimize this mean. This approach is realized in the original code KEDRO for design of experiments, analysis and multiobjective robust optimization
