  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.
