“…For this reason, TBE control charts are often called exponential control charts. Since Lucas (1985) and Vardeman and Ray (1985) first proposed the TBE control chart, many recent studies have focused on the TBE control chart, including the exponential chart (Chan, Xie, and Goh 2000;Chan et al 2002;Jones and Champ 2002;Xie, Goh, and Ranjan 2002;Zhang, Xie, and Goh 2005;Zhang, Xie, and Goh 2006;Zhang et al 2011;Dovoedo and Chakraborti 2012), the exponential CUSUM chart (Lucas 1985;Gan 1994;Borror, Kates, and Montgomery 2003;Cheng and Chen 2011;Qu et al 2013;Zhang, Megahed, and Woodall 2014) and the exponential EWMA chart (Gan 1998;Ozsan, Testik, and Wei 2010;Chen 2012).…”
