Design of Experiments: Factorial Design

追加: 2026-06-03

[00:00:00]In the case of a three-factor DOE, the values can be represented in a cube where the corners represent the eight test conditions.

[00:00:08]Thus, experiments are carried out along the respective space.

[00:00:12]Additional experiments are performed at the central point and points between the low and high factors to determine the intrinsic variability and if there is curvature of the response surface.

[00:00:22]Subsequently, a mathematical model can be established to display the responses graphically.

[00:00:28]From the contour plot, one can read the relationship between the factors and the responses.

[00:00:33]In order for the DOE approach to be regarded as a success, it is essential that any experiments are performed in a systematic way within an accurately controlled framework under reproducible conditions.

[00:00:45]Therefore, the requirements for the experimental setup, the experiment itself, and the execution are high and demand a high degree of flexibility, precision, and reproducibility from the synthesis [music] tools with which the experiments are carried out.
