Optimization of container terminal layouts in the seaport-case of Port of Montreal

Abstract

The intermodal transportation system plays a pivotal role in a global supply chain. Despite the benefits of intermodal transportation, it still has negative impacts, which are associated with congestion and emission. Greenhouse Gas (GHG) emission is highly associated with the transportation industry, and the share of the transportation sector is growing at a rapid pace. This paper discusses intermodal transportation and its eects on port effciency. We proposed a new layout for the container terminal in the seaport in order to decrease cost as well as emission generated by the port operations. The proposed layout can improve the sustainability of port activities by decreasing the distance between the berth and interface points as well as avoiding double handling. We propose multi-objective optimization using the "-constraint method to solve this problem. The model was tested through a case study of the Port of Montreal in Canada. The findings reveal that the proposed layout resulted in considerable emissions and costs reduction. Compared with the current layout of Port of Montreal, the proposed layout achieved a reduction of 46.5% in the total transportation cost of the containers to their final destination, as well as 21.6% in the emission.
