 Robust empty container repositioning considering foldable containersSangyoon Lee and Ilkyeong Moon European Journal of Operational Research, 2020, vol. 280, issue 3, 909-925 Abstract: Because of the extreme imbalance in intercontinental trade, the repositioning of empty containers creates a significant problem for shipping companies. There are many efforts to reduce the cost of repositioning empty containers, one of which is a foldable container. This paper proposes a robust formulation for the empty container repositioning problem considering foldable containers under demand uncertainty. The robust formulation can be used as a tractable approximation of a multistage stochastic programming formulation which is computationally intractable. Moreover, the robust formulation requires only limited information about the distribution of demand to replicate real-world situations. Computational results show that the proposed formulation performs well in terms of operating costs and there exists a significant cost-saving effect when foldable containers are used in maritime transportation.
