... In Taguchi analysis, the signal-to-noise (S/N) ratio is used as a measure of robustness, which is used to identify control factors that reduce variability in a product or process by minimizing the effects of uncontrollable or noise factors (Jamshidi et al., 2012). Thus, the S/N ratio is a significant way to determine the influencing parameters by calculating minimum variance (Shunmugesh and Pratheesh, 2020). Higher values of the S/N ratio identify control factor settings that minimize the effects of the noise factors. ...
