- W3199638861 abstract "Shipowners seek to increase their profits by optimizing the operation of their available fleet, increasing its capacity, and reducing costs while meeting the customers’ demands. Ship routing stands out as a relevant topic of study, especially for tramp shipping companies, due to the high competitivity on this market, which highlights the importance of providing reliable and price competitive services. This work presents a mixed-integer programming formulation to maximize the profit of an actual tramp shipping company. The studied problem considers pick-up-and-delivery for different cargoes, partial contract orders, time window restrictions, heterogeneous fleet, cargo split, varying navigation speeds, and guaranteed transit time terms. We perform computational experiments with real data from the studied company, comparing the achieved solutions with those developed by the company following their current planning process. The mathematical formulation improves the existing solutions in all tested cases with total costs up to 7% smaller, including fuel, port, and ship’s operational costs." @default.
