Abstract
The optimization of the various processes from the development to production of the product is carried out. However, there are many cases that are the approximation solution by using RSM(response surface modeling) and also request a local optimum solution by utilizing the mathematical programming. And generally most of the design variables in optimum object include the continuous numbers and discrete numbers. Thereupon, hi addition to the former method of zone division for the continuous numbers, we propose the new method that deal with the continuous and discrete design variables. The effectiveness of proposed method has been confirmed by several numerical examples and a real design problem.
