Construction of efficient unbalanced mixed-level supersaturated designs

The purpose of this article is to generate mixed-level unbalanced or non-U-type supersaturated designs using computer intensive procedures. Lower bounds to modified E(fUNOD) and χU2(D) criteria have been used to measure the efficiency of the generated non-U-type mixed-level supersaturated designs. The catalogue of unbalanced mixed-level supersaturated designs has been given. The designs generated are such that no two columns are fully aliased.
