Assessment of empty container repositioning policies in maritime transport
Empty container repositioning is an important issue in the liner shipping industry. Generally stated, two groups of mathematical models have been proposed to tackle this issue. The first group aims to derive time-dependent origin-destination matrices that specify the number of empty containers to be repositioned at a decision epoch; the second group aims to develop effective statefeedback control policies consisting of dynamic decision-making rules. There is, however, a lack of research into the comparison of these two groups, especially with regard to realistic cases subject to uncertainties. The purpose of this paper is to evaluate and compare the performances of some typical repositioning policies from these two groups and to shed light on their relative merits and suitability in various realistic scenarios
