“…ten studies at the single plant level (Folinas et al, 2015;Glover et al, 2014;Goriwondo et al, 2011;Hossain and Uddin, 2015;Jiménez et al, 2012;Parthanadee and Buddhakulsomsiri, 2014;Rahimnia et al, 2009;Sa'udah et al, 2015;Shobha and Subramanya, 2012;Tanco et al, 2013) and two studies at the supply chain level (Seth et al, 2008;Taylor, 2005). Although state maps were in general graphically illustrated, two additional studies (Engelund et al, 2009;Sathiyabama and Dasan, 2013) only described the current and future states. There were six studies (Ahmed et al, 2015;Darlington and Rahimifard, 2006;Kennedy et al, 2013;Lehtinen and Torkko, 2005;Melvin and Baglee, 2008;Vlachos, 2015) that only used the current state map and one study (Noorwali, 2013) that gave a description of the current situation at a single plant level, against three studies (Francis et al, 2008;Simons et al, 2003;Taylor, 2006b) at a supply chain level.…”
