In this paper, the problem of constructing optimal blocked regular fractional factorial designs is considered. The concept of minimum aberration due to Fries and Hunter is a well-accepted criterion ...

Experimentation is a vital part of the scientific method. Most problems in science require observation of the system at work and experimentation to elucidate information about how the system works. In ...

In recent years, there has been increasing interest in the study of asymmetrical fractional factorial designs. Various new optimality criteria have been proposed from different principles for design ...
