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 ...

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 a two-level factorial experiment, the authors consider designs with partial duplication which permit estimation of the constant term, all main effects and some specified two-factor interactions, ...

Methods for designing and analyzing industrial experiments. Blocking; randomization; multiple regression; factorial and fractional factorial experiments; response surface methodology; Taguchi’s robust ...
