Fractional Factorial Plans

TLDR
Fractional plans and orthogonal arrays have been extensively studied in the literature, see as discussed by the authors for a survey of some of the most relevant works. But nonexistence of fractional plans has been discussed.

Quality improvement in the manufacture of liquid crystal displays using uniform design

TL;DR: In this paper, a successful application of uniform design in the manufacture of liquid crystal dsplays was reported, in which the information obtained from the experiment resulted in a significant improvement of the percentage yield of the process.

An algorithmic approach to constructing mixed-level orthogonal and near-orthogonal arrays

TL;DR: A combinatorial relationship between a mixed-level array and a non-resolvable incomplete block design (IBD) with varying replications (and its dual, a resolvable IBD with varying block sizes) is shown.

Connections between uniformity and aberration in general multi-level factorials

TL;DR: In this paper, the second-order polynomials of indicator functions for these three discrepancies were investigated and the relationship between them and the generalized wordlength pattern was investigated, and conditions under which a design having one of these minimum discrepancies is equivalent to having generalized minimum aberration (GMA).

Binary operations and canonical forms for factorial and related models

TL;DR: Binary operations on commutative Jordan algebras are used to extend the grouping of treatments in blocks and the taking of fractional replicates to models where factors have arbitrary number of levels as mentioned in this paper.

Lower bounds of various criteria in experimental designs

TL;DR: In this paper, lower bounds of various criteria in experimental designs will be reviewed according to methodology of their construction, including most well-known ones which are frequently used as benchmarks for orthogonal array, uniform design, supersaturated design and other types of designs.

Non-Orthogonal Designs of Even Resolution*

TL;DR: In this paper, it was shown that the smallest resolution 4 designs for n factors at two levels must contain at least 2n runs, and that "foldover" designs are available with 2 n runs.
