Response surface methodology is a method for constructing global approximations to system behaviors based on results calculated at various points in the design space. The technique of reducing the design space was used to achieve the best approximation efficiently. The stepwise regression was adopted to control the relationship between a set of variables and a response. With the help of response surface method and optimization technique, the design analyst can obtain optimum design easily and the savin g of computer time is significant.
