In this paper, the projection uniformity of a class of OLHDs with more general run sizes in two dimensions is discussed, i.e., the grid layering properties. The results show that the design can achieve stratifications on s × s grids in any two dimensions;most column pairs can achieve stratifications on finer s2 × s and s × s2 grids when the two columns are from the same group that are not adjacent to each other, and some column pairs achieve stratifications on s2 × s2 grids.展开更多
