Abstract
Material searching technology using optimization technique has been developed in order to speed up material design. This technology employs a response surface method which is used in an optimized calculation instead of material search using experiments and simulation in the past. The proposed technology has two key features: (1) Kriging model which can approximate non-linear functions is used as a response surface method in order to search the target material, (2) the Kriging model can be constructed by a fewer sampling points by selecting appropriate points in displayed design space. The effectiveness of the proposed technology was demonstrated by applying it to the material searching of electrode filter. It was found that the proposed technology reduced the material searching time by 70% compared with that for previous methods.
