“…To provide insights on promising solution methodologies and behavior of the system, some researchers have focused on cases with one inbound and one outbound dock (Yu and Egbelu, 2008;Chen and Song, 2009;Vahdani and Zandieh, 2010;Boloori Arabani et al, 2010, 2011bLiao et al, 2012;Amini and Tavakkoli-Moghaddam, 2016;Keshtzari et al, 2016), but cases with multiple inbound and outbound docks have been becoming more frequent (Bellanger et al, 2013;Van Belle et al, 2013;Ladier and Alpan, 2018;Assadi and Bagheri, 2016;Cota et al, 2016;Wisittipanich and Hengmeechai, 2017). The scheduling problem is usually modeled with the goal of minimizing total operation time (Yu and Egbelu, 2008;Chen and Song, 2009;Vahdani and Zandieh, 2010;Liao et al, 2012;Keshtzari et al, 2016;Bellanger et al, 2013;Cota et al, 2016;Wisittipanich and Hengmeechai, 2017;Boloori Arabani et al, 2011a;Shakeri et al, 2012;Gelareh et al, 2016;Bazgosha et al, 2017). It is also possible to find examples of other metrics: Storage (volume or cost) or material handling (Ladier and Alpan, 2018;Rahmanzadeh Tootkaleh et al, 2016;Maknoon et al, 2017), travel distance (Chmielewski et al, 2009) and earliness and/or tardiness alone (Boloori Arabani et al, 2010;Assadi and Bagheri, 2016) or combined with others such as travel time (Van Belle et al, 2013) and probability of breakdowns (Amini and Tavakkoli-Moghaddam, 2016).…”
