Fractional Factorial Split-Plot Designs for Robust Parameter Experiments

Abstract

For robust parameter designs, it has been noted that performing the experiment as a split plot often provides cost savings and increased efficiency. Thus experiments are often performed using fractional factorial split-plot designs. We consider how one should best choose such designs for robust parameter experiments and what is meant by maximum resolution and by minimum aberration in this context under various experimental settings.

KEY WORDS:

• Minimum aberration
• Resolution
• Restricted randomization
