Full factorial DOE, or Design of Experiments, is a method of designed experimentation. Using this method you manipulate the controllable factors (independent variables or inputs) in your process at ...

This paper describes two level fractional factorial designs in which some of the treatment combinations are duplicated. As is well known, the duplicated runs provide ...

A class of incomplete three level factorial designs useful for estimating the co-efficients in a second degree graduating polynomial are described. The designs either meet, or approximately meet, the ...
