| Popis: | This paper introduces an algorithmic approach to constructing 2-level foldover designs using the minimum G2-aberration criterion (Tang & Deng, 1999). Our algorithms can find designs without fully aliased 2-factor interactions (2FIs). As a result, follow-up runs which are used to disentangle the 2FI from another might become unnecessary. The constructed designs are compared with the efficient 2-level foldover designs of Errore et al. (2017), the 2-level designs of strength 3 for 32, 40 and 48 runs of Schoen & Mee (2012), and some regular fractional factorial designs for up to 64 runs. A catalogue of minimum G2-aberration 2-level foldover designs for up to 32 factors is given. |
