62K05 Optimal designs
62J15 Paired and multiple comparisons

Abstract:
For paired comparison experiments involving options described by a set of two-level factors a new method for generating exact designs is presented. These designs allow the efficient estimation of main effects and first-order interactions and perform better than alternative designs in the literature.
