Integrated maritime fuel management with stochastic fuel prices and new emission regulations
Gu, Yewen; Wallace, Stein W.; Wang, Xin (Journal article; Peer reviewed, 2018)Maritime fuel management (MFM) controls the procurement and consumption of the fuels used on board and therefore manages one of the most important cost drivers in the shipping industry. At the operational level, a shipping ... -
Planning for charters: A stochastic maritime fleet composition and deployment problem
Wang, Xin; Fagerholt, Kjetil; Wallace, Stein W. (Journal article; Peer reviewed, 2017)This paper introduces a chartering problem that arises in the shipping industry. The chartering decisions determine the time-charter contracts to enter into, in particular, how many ships of each type to charter in, and ... -
Problem-based scenario generation in stochastic programming with binary distributions - Case study in Air Traffic Flow Management
Narum, Benjamin S. (Master thesis, 2020)Scenario generation is about selecting which outcomes of the future are worth considering when solving a stochastic optimization problem, and to remove redundancies in the full representation of the stochastic phenomenon ... -
Stochastic Network Design for Planning Scheduled Transportation Services: The Value of Deterministic Solutions
Wang, Xin; Crainic, Teodor Gabriel; Wallace, Stein W. (Journal article; Peer reviewed, 2018)We study the value of deterministic solutions, in particular their quality and upgradability, in addressing stochastic network design problems, by analyzing their time-dependent formulations known as scheduled service ... -
The Impact of Bunker Risk Management on CO2 Emissions in Maritime Transportation Under ECA Regulation
Gu, Yewen; Wallace, Stein W.; Wang, Xin (Chapter, 2018)The shipping industry carries over 90% of the world’s trade, and is hence a major contributor to CO2 and other airborne emissions. As a global effort to reduce air pollution from ships, the implementation of the ECA (Emission ...
