“…MRSN ratio method (Nian et al, 1999), WSN ratio method (Shiau, 1990;Tai et al, 1992), GRA method (Lin et al, 2009), and VIKOR method (Tong et al, 2007) are quite simpler/robust in accordance to their computational procedures. There are some other multiresponse optimization techniques (Sahin & Motorcu, 2008;Sardinas et al, 2006;Jeyapaul et al, 2006;Liao, 2006), which use complex mathematical/statistical tools and are, therefore, inconvenient to be used by the industrial personnel with little background in statistics and knowledge of software.…”
