Construction of optimal supersaturated design with large number of levels

Abstract

Inspired by the ideas of column and row juxtaposition in Liu and Lin (2009) and level transformation in Yamada and Lin (1999), this paper presents a new method for constructing optimal supersaturated designs (SSDs). This method provides a convenient way to construct mixed-level designs with relatively large numbers of levels, avoiding the blind search and numerous calculations by computers. The goodness of the resulting SSDs is judged by the χ 2 ( Yamada and Lin, 1999 and Yamada and Matsui, 2002) and J 2 ( Xu, 2002) criteria. Some nice properties of the new designs are also provided.
