Nonregular designs are becoming popular and preferred choices in many areas of scientific
investigation for their flexibility and run size economy. The lack of simple design structure is …

Due to recent advances in the development of laboratory equipment, large screening
experiments can now be conducted to study the joint impact of up to a few dozen factors …

Table S. 1 lists all parallel flats classes for f= 7, 8, 9, extending the parallel flats classes in
Table 6. Table S. 2 lists the 12 possible parallel flats classes for QC designs of 256 runs …

Two-level fractional factorial designs are often used in screening scenarios to identify active
factors. This article investigates the block diagonal structure of the information matrix of …

Two-level parallel flats designs (PFDs) are nonregular designs that retain some of the
simplicity of regular fractional factorial designs. PFDs have many desirable properties, such …

Nonregular designs are attractive, as compared with regular designs, not just because they
have flexible run sizes but also because of their performances in terms of generalized …

Exchange-type algorithms have been commonly used to construct optimal designs. As these
algorithms may converge to a local optimum, the typical procedure requires the use of …

Abstract Design of experiments is an effective, generic methodology for problem solving as
well as for improving or optimizing product design and manufacturing processes. The most …
