Container Ship Fleet Scheduling Based on Reinforcement Learning Considering Carbon Emissions

International Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
Against the backdrop of the continuous development of ship informatization, joint scheduling for the entire fleet within a region brings numerous advantages. The optimization of scheduling problems for such a regional fleet, in addition to considering the number of orders completed, reducing operational costs, and further reducing carbon emissions, is ...

Real Time Energy Efficiency Operational Indicator (EEOI): Simulation Research from the Perspective of Life Cycle Assessment

Journal of Physics: Conference Series, 2020
Abstract In order to evaluate the effect of CO2 emissions during ship building, maintenance and scrapping on energy efficiency, a real time EEOI definition was put forward, a life cycle assessment calculation framework was established, and a ship propulsion model with main diesel engine was built. A bulker carrier YUMING was taken as the
