“…See Miettinen (2008), Miettinen, Ruiz, and Wierzbicki (2008) for details of non-interactive and interactive methods. Surrogate-based methods are commonly used in the literature to alleviate computational cost (Jones, 2001;Regis & Shoemaker, 2012;Audet, 2014;Tan, 2015;Dengiz et al, 2009;Chih, 2013;Reis dos Santos & Reis dos Santos, 2011;Hurrion, 2000;Kleijnen & van Beers, 2013;Van Beers & Kleijnen, 2003;Yang & Tseng, 2002;Mehdad & Kleijnen, 2015;Park, Yum, Hung, Jeong, & Jeong, 2016). The basic idea in such methods is to introduce a computationally less expensive problem called a surrogate problem and to replace the original problem with the surrogate one.…”
