✦ Synopsis

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 confounded with several two-factor interactions. Moreover, the recovery of the former from such partial confounding is possible in some cases by eliminating the latter.

A weighted A-optimality (WA-optimality) criterion is discussed for selecting a fractional 2" factorial design of resolution V. A WA-optimality criterion having one weight may be considered for designs. It is shown that designs derived from orthogonal arrays are WA-optimal for any weight. From a WA-o

This paper presents three kinds of balanced fractional 3 m factorial designs of resolution IV such that (A) all the main e ects and the linear by linear and the linear by quadratic components of the two-factor interactions are estimable, (B) all the main e ects and the linear by linear ones of the t
