摘 要:
Space-filling designs with superior low-dimensional properties are highly required in computer experiments. Strong orthogonal arrays (SOAs) represent a class of such designs that outperform ordinary orthogonal arrays in their stratification properties within low dimensions. Nevertheless, existing methods for constructing SOAs often rely on regular designs, thereby restricting the run sizes to prime powers. This study presents new construction methods for three types of designs: SOAs of strength two plus, column-orthogonal SOAs (OSOAs) of strength two plus, and SOAs of strength three. The resulting designs have run sizes equal to twice an odd prime power and contain no replicated runs, filling gaps in run sizes left by existing constructions. The projection properties of Addelman–Kempthorne orthogonal arrays are instrumental in the development of these construction methods.
