What is a Taguchi orthogonal array?

Taguchi Orthogonal Array (OA) design is a type of general fractional factorial design. It is a highly fractional orthogonal design that is based on a design matrix proposed by Dr. Genichi Taguchi and allows you to consider a selected subset of combinations of multiple factors at multiple levels.

What is Taguchi L9 orthogonal array?

The Taguchi’s orthogonal array L9 (3^4) is used in order to estimate the factors that influence the performance criteria and also which factors are more important than others. The Analysis of Mean (ANOM), S/N ratio, Tukey Method and Analysis of variance (ANOVA) is used in order to get the objectives of this paper.

What is meant by Taguchi’s loss function?

Wikipedia defines Taguchi loss function as the graphical depiction of loss to describe a phenomenon affecting the value of products produced by a company. It emphasizes the need for incorporating quality and reliability at the design stage, prior to production.

What is orthogonal technique?

An orthogonal method is an additional method that provides very different selectivity to the primary method. The orthogonal method can be used to evaluate the primary method.

What is orthogonal array in software testing?

Orthogonal array testing is a black box testing technique that is a systematic, statistical way of software testing. It is used when the number of inputs to the system is relatively small, but too large to allow for exhaustive testing of every possible input to the systems.

What is the advantage of Taguchi’s quality loss function?

Thus Taguchi loss function is very valuable that transform the variation from nominal value with financial depiction. In other words it gives the relation between lowering the variation from target to the financial benefit.

What is Taguchi’s definition of quality?

Taguchi stated that “quality is the loss a product causes to society after being shipped, other than losses caused by its intrinsic functions.” Taguchi asserted that losses in his definition “should be restricted to two categories: (1) loss caused by variability of function, and (2) loss caused by harmful side effects. …

What is Taguchi’s view of quality?

In engineering, the Taguchi method of quality control focuses on design and development to create efficient, reliable products. Its founder, Genichi Taguchi, considers design to be more important than the manufacturing process in quality control and seeks to eliminate variances in production before they can occur.
