  • Resolution III fractional factorial designs are often used in the initial phases of an experiment to screen factors, but it may be desirable to include partial replication of the design to allow for the unbiased estimation of error while maintaining the orthogonality of the main effects. This paper proposes a new class of partially replicated two-level fractional factorial designs based on Hadamard matrices. Construction of these designs is discussed and their relative performance is evaluated by comparing them with competing fractional factorial designs.
