“…Reisman et al (1997) reviewed practical cases and concluded that the flowshop problem has many real life applications. This applicability of the flowshop is also highlighted in the many exiting reviews from the literature like Framinan et al (2004), Ruiz and Maroto (2005), Hejazi and Saghafian (2005) and Gupta and Stafford (2006). As a matter of fact, once generalized to hybrid flowshops or flexible flowline problems, many production problems can be modeled after a flowshop (Linn and Zhang, 1999;Vignier et al, 1999;Wang, 2005;Quadt and Kuhn, 2007;Ruiz and Vázquez-Rodríguez, 2010;Ribas et al, 2010).…”
