Abstract

Response surface methodology is applied often in industrial experiments to find the optimal conditions for the design factors. Response surface methodology involves three main steps: screening potential factors, seeking a region around the global optimum using the path of steepest ascent, and estimating the true model for the response. 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.
