Design of experiments provides a new way to
optimize technological processes. Today, more
and more engineers and scientists use design of
experiments in their work, such as formulation,
process optimization. product design and quality
control. There is a major difference between the
traditional experiment planning and the method
based on a design of experiments approach. The
traditional method is to vary one variable at a
time. An investigation based on design of
experiments varies many variables at the same
time using a matrix covering the desired
variables and their ranges. As a result, many
variables can be investigated simultaneously and
interactions among variables can be obtained
from the test. Methods using design of
experiments make it possible to reduce the
number oftests significantly, resulting in less
test time and lower test costs.
