Characteristics of orthogonal array designs are: Levels appear in equal numbers. Combination of A1B1, A1B2, etc. appear in equal numbers. Effect of factor A can be separated from the effects of B and C. Orthogonal Arrays Standard Orthogonal Arrays • See table 7.1 on Phadke page 152 • Note: You can never use an array that has fewer rows than DOF req’d • Note: The number of factors of a given level is a maximum • You can put a factor with fewer columns into a column that has more levels – … This parameter selection is based on the resolution level of the Taguchi orthogonal array. For the three level four factor analysis Taguchi preferred L9 and L27. From the above arrays L27 had higher resolution. 2.3 Taguchi Approached Parameter Values SLNO SHELL SIZE TUBE OUTER DIAMETER BAFFLE SPACING TUBE PITCH HEAT TRANSFER COEFFICIENT
Firstly Orthogonal Array Testing Strategy introduces in this paper, and.Starting as a programmer in 1983, James turned to testing in 1987 at Apple. Used to create pairwise test sets include Orthogonal Arrays, a technique borrowed.Orthogonal testing- Orthogonal array testing is a black box testing. orthogonal array testing strategy pdf Thousands of orthogonal pairs were revealed with sufficient selectivity for use in biological environments. Over 100 pairs were validated in vitro, and three were applied in cell and animal models. The parallel screening method is both generalizable and scalable and will streamline the search for larger collections of orthogonal probes. Taguchi orthogonal array design, a statistical software is applied to n-hexane reforming. The purpose is to identify the most significant process variable in reforming conditions favouring n-hexane conversion to high aromatics and isomers and low cracked and coke precursor reformate products.

Abstract. In this article, we use orthogonal arrays (OA's) to construct Latin hypercubes. Besides preserving the univariate stratification properties of Latin hypercubes, these strength r OA-based Latin hypercubes also stratify each r-dimensional margin.Therefore, such OA-based Latin hypercubes provide more suitable designs for computer experiments and numerical integration than do general ... and so on Rao [1-4] Orthogonal arrays of strength 2 were found useful in the construction of other combinatorial arrangements. Bose, Shrikhande and Parker  used it in the disproof of Euler’s conjecture. Ray-Chaudhari and Wilson [6-7] used orthogonal arrays of strength 2 to generate resolvable balanced incomplete block designs.

A run is an experimental condition or factor level combination at which the response is measured. The number of runs is the number of rows in the basic Taguchi orthogonal array. It indicates the number of distinct control factor combinations to be run in the experiment. Suppose you have a design with 3 control factors with 2 levels each.

It is statistical testing approach especially useful when system to be tested has huge data inputs. Orthogonal array testing helps to maximize test coverage by pairing and combining the inputs and testing the system with comparatively less number of test cases for time saving.
