  Orthogonal arrays with clear two-factor interactions are very attractive for industrial experiments as they provide  a class of designs that are robust to nonnegligible two-factor interactions.  If prior knowledge suggests that some two-factor interactions are  negligible before running the experiment, then designs can be found that allow additional factors to be studied while remaining robust to the nonnegligible two-factor interactions. This is done through partially clear two-factor interactions. We study the existence and construction of such robust designs in this paper. Several construction results are presented and examples are provided for illustration.  We also prove a result that establishes an upper bound on the maximum number of clear two-factor interactions in an orthogonal array. This is a joint work with my student Ryan Lekivetz.
