Abstract
In globalized manufacturing industry, we need suitable safety stock placement. But it is difficult to use exhaustive methods because we have to choose the amount of safety stock to each warehouse from many choices. Existing method has a problem of computational cost for simulation to get evaluation value. In this study, we focus on Kriging to reduce the number of times for simulation. It is the method to predict solutions' value by approximating the relation between design variables and responses with some kind of functions. In this paper, we show the new method is more efficient than the existing method.
