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 criteria have been used to measure the efficiency of the generated non-U-type mixed-level supersaturated designs. The...

The robustness aspects of block designs for complete diallel crossing plans against the exchange of one cross using connectedness and efficiency criteria have been investigated. The exchanged cross may have either no line in common or one line in common with the original cross. It has been found...
