In this paper, we investigate a model which contains all the main effects and all the two-factor interactions with the most important factor. We shall show that Mitchell's rules are no longer applicable in many cases and we shall present a general procedure to find D-optimal designs. (~

Fractional factorial designs have a long history of successful use in factor screening experiments. When only a few factors are expected to be relevant, knowledge of their low-dimension projections is valuable. The projection properties of the 2~ -m fractional factorial design into any k dimensions
New fractional 2" factorial designs obtained by assigning factors to fractions of m columns of new saturated two symbol orthogonal arrays which are not isomorphic to the usual ones are proposed. Contrary to the usual assignment, examples show that some main effects are not totally but partially conf
