D-optimal orthogonal array minus t run designs

ABSTRACT

This article considers the design performance of orthogonal arrays in which one or more runs are missing at random. We focus on orthogonal arrays of index unity and on the 18 run ternary arrays.

KEYWORDS:

• Fractional factorial design
• mixed-level array
• missing runs
