Space Filling Split Plot Design using Fast Flexible Filling

Abstract: In this article, an adaption of an algorithm for the creation of experimental designs by Lekivetz and Jones (2015) is suggested, dealing with constraints around randomization. Split-plot design of experiments is used, when the levels of some factors cannot be modified as easily as others. While most split-plot designs deal in the context of I-optimal or D-optimal designs for continuous response outputs, a space filling design strategy is suggested in here. The proposed designs are evaluated based on different design criteria, as well as an analytical example.
