Recently, refinery products are being traded frequently in global markets. Such international trades involve special features such as exchange rates, tariffs and freight rates. In this work, vessel scheduling for transportation among countries, inventory management for storage tanks at each global port and distribution management in the global markets are studied for supplying refinery products. A mixed-integer linear programming (MILP) model maximizing the profit is developed and exchange rates, tariffs and freight rates are considered as global issues here. The efficacy of the proposed model is illustrated through a real-scale example involving 1 exporting country, 3 importing countries, 4 global ports, 3 foreign markets and 1 domestic market. |
