Explain orthogonal array
WebThe Taguchi method (TM) is a problem-solving technique to help improve process performance, to increase efficiency and productivity. The Taguchi method is centred around reducing potential variations in a process through design of experiments. The objective of using the methodology is to produce high-quality products with low costs to the ...
