Response Surface Methodology

Definition

Response Surface Methodology (RSM) is a statistical and mathematical technique used for modeling and analyzing problems in which several variables influence the output or response. It helps in optimizing processes by developing an approximate model of the response based on a limited number of experiments. This approach is particularly useful when dealing with complex systems where multiple responses need to be analyzed simultaneously, making it relevant for tasks like optimization and surrogate modeling.
