Several types of experimental designs are commonly used in RSM, including:
- Central Composite Design (CCD): Widely used for fitting a quadratic surface, which can help in understanding the interaction between variables. - Box-Behnken Design (BBD): Useful when the experiment involves three or more factors. It requires fewer runs than CCD. - Taguchi Method: Focuses on robust design by reducing variation and improving quality. It's particularly useful for nanofabrication processes.
