“…Cross docking systems attract many researches to study and develop the concept of cross docking as well as providing some methods in order to improve the efficiency of the cross docking systems. In this field, researchers have studied several cross docking related topics such as system design (Apte and Viswanathan, 2000;Santos et al 2013;Jayaraman and Ross, 2003;Sung and Song, 2003;Bartholdi and Gue, 2004;Sung and Yang;, simulation (Rohrer, 1995), vehicle routing (Mohtashami et al 2015;Lee et al, 2006;Wen et al, 2009), dock door assignment (Oh, 2006;Kuo, 2013), vehicle sequencing and scheduling (Bellanger et al 2013;Liao et al, 2012), distribution planning (Chen et al, 2006;Musa et al, 2010), and transshipment scheduling (Larbi et al, 2011). Since the scope of this paper is around vehicle scheduling, this subject is reviewed in more details as follows.…”
