Abstract:

Response surface methodology involves three main steps: screening potential factors, the path of steepest ascent, and estimating the true model for the response. Response surface methodology is applied quite frequently in industrial experiments to find optimal conditions for the design factors. Many of these experiments involve randomization restrictions and can be thought of as split-plot experiments. This paper investigates the path of steepest ascent within a split-plot structure. Three methods are proposed for calculating the coordinates along the path.
