Covering arrays detect interactions among factors by ensuring that each combination of levels for at most t factors is tested in at least one run (the strength t is the maximum number of interacting factors examined). D-optimal designs ensure orthogonality rather than just coverage. Hence D-optimal designs lend themselves to measurement of interactions, while covering arrays may alias some of the...
