Abstract
The approach for application of optimization technologies has been chiefly cultivated in a research and an analytical field up to now. Recently, the demand that applies it to the design field is rising rapidly. However, the optimization tool should acquire some expertise and how to operate it because it is generally multifunctional. Therefore, it has not arrived to spread enough to designers. Then, we are developing the design-supporting tool that reflects the optimization know-how that our company has accumulated by using Microsoft Excel as a user interface. This paper explains the outline, the background and the case examples.
