Sequential Experimentation

General augmentation techniques such as foldover and §semifold have been a common practice in industrial §experimentation for many years. Even though these §techniques are extremely effective in maintaining §balance and orthogonality, they possess serious §disadvantages such as the inability to decouple §specific terms and a high level of inefficiency. §This book aims for a sequential experimentation §approach capable of improving the drawbacks of the §general methods while maintaining some of its §benefits. This text proposes an algorithm for §sequential augmentation of fractional factorial §designs resolution III. It also explores new §possibilities for augmentation of efficient mixed-§level designs (EAs) and provides a new methodology §for sequential augmentation of mixed resolution §robust designs. The work presented here extends the §current limits of sequential experimentation for §resolution III, mixed-level and robust designs and §provides a viable alternative to experimenters in §situations in which financial restrictions do not §allow the implementation of a general method.
