Response Surface Methodology (RSM)

Definition

Response Surface Methodology (RSM) is a statistical technique used for optimizing processes by analyzing the relationships between multiple variables and their effects on a response variable. RSM helps identify the optimal conditions for a system by creating a mathematical model that represents these relationships, often utilizing experimental design to efficiently explore the input space and capture interactions between variables.
