Design process of a product or product characteristics can be formulated in different ways. In order to develop design optimization system, it is required to define optimization problem based on different design formulations of same product characteristics because differences of formulations produce a big influence on the optimum solution. Therefore, it is important to examine the validity of the formulations of actual design activities. In this paper, design simulation system to examine the validities of formulations is developed, in which designer attempts various formulations of design activities and system automatically execute optimizations based on the input given by the designer. Moreover, some different formulations on ship initial design are evaluated by using the proposed system.
