Response surface methodology (RSM) is a collection of statistical design and numerical
optimization techniques used to optimize processes and product designs. The original work …

This text presents a unified treatment of experimental designs and design concepts
commonly used in practice. It connects the objectives of research to the type of experimental …

The past decade has seen rapid advances in the development of new methods for the
design and analysis of split-plot experiments. Unfortunately, the value of these designs for …

Few things impact our everyday lives more than those products that are manufactured by
mixing ingredients together. From the time we arise in the morning until we retire at night, we …

Quality has become an important source of competitive advantage for the modern company.
Therefore, quality control has become one of its key ac tivities. Since the control of existing …

Many industrial experiments involve two types of factors: those that are hard-to-change and
those that are easy-to-change (ETC). Hard-to-change (HTC) factors have levels that are …

We introduce a new method for generating optimal split-plot designs. These designs are
optimal in the sense that they are efficient for estimating the fixed effects of the statistical …

A culmination of the author's many years of consulting and teaching, Design and Analysis of
Experiments with SAS provides practical guidance on the computer analysis of experimental …

There are basically three general degrees of freedom to control the final properties of any
product manufactured in a blending operation: the selection of raw materials, the ratios in …

Natural fermentative medium for selenium-enriched yeast (Saccharomyces cerevisiae)
culture was investigated using response surface methodology (RSM). The medium with a …
