Abstract
CAE technology is indispensable to present design & development in every industries. But because it is the main purpose that the CAE tools are used for grasp the phenomenon, it owes a good deal to expert engineers that in order to do the better design. In this context, optimization tools have started to get a lot of publicity as the ways to improve the situations. The optimization tools are used for not only finding the optimal solutions but also improve the system of design & development of its own through the functions in optimization tool; Sampling method, Multi-objective robust design optimization, Response surface method and Multi criteria decision making. This report shows these technical functions through case studies.
