“…The objective of these experiments is to make the products and processes robust (or insensitive) to undesirable disturbances such as environmental and manufacturing variations. A number of successful applications of DoE and Tms for improving product quality, process performance and reducing variability in processes have been reported by many manufacturers over the last ten years (Antony et al,1996;Kumar and Tobin, 1990;Ramberg et al, 1989;Sheaffer et al, 1990). However, research has shown that the application of such techniques by the engineering fraternity in industries is limited .…”
