We introduce a new class of designs, marginally coupled designs, for computer experiments with both qualitative and quantitative variables. These designs maintain an economic run size with attractive space-filling properties. The design points for quantitative factors form a Latin hypercube design. In addition, for each level of any qualitative factor of a marginally coupled design, the corresponding design points for quantitative factors form a small Latin hypercube design. Existence of the proposed designs is studied. Constructions are provided for various types of designs with qualitative factors.
