... for multivariate process control. Mahalanobis distance, Taguchi’s orthogonal array, and the main effect plot concept are used to identify the key influential variable responsible for the out-of-control situation. The Andrews function plot and nonlinear optimization help to identify direction and necessary...

... ratio Design of experiments Mahalanobis distance Orthogonal arrays Taguchi’s design of experiment (DOE), which is also called robust design, is one of the most successful methods of experiment in practice. It is cost effective and it causes increase efficiency in producing a product...

... novel unsupervised classification algorithms called Unsupervised Mahalanobis Distance Classifier (UNMDC) are developed based on Mahalanobis' distance for identifying “abnormals” as individuals (or, groups) including feature selection. The identification of “abnormals” is based on the concept...
