Abstract
In Roll-on/Roll-off stowage planning, there are two main elements of uncertainty: The arrival time of the cargo and weight. The weight of the cargo is often not known precisely at loading time, thus forcing the loading planner to be conservative when creating their stowage plan. To our knowledge, the impact of the uncertain weight has not yet been studied. We thus propose the Roll-on/Roll-off stowage planning problem with respect to uncertain cargo weights. We introduce a two-stage stochastic model that places cargo in the first stage and ensures the vessel's stability in the second stage. The model aims to stow as much cargo as possible under uncertainty while ensuring that the vertical centres of gravity, shear force and bending moment are within their respective limits. The uncertain weight is determined by a fitted weight distribution from an industry partner. We hope that our finding can shed light on the impact of the uncertainty of the cargo weight and if it is beneficial to include it in stowage planning problems. Further, we will study the effect of binning cargo into weight categories and how the number of bins impacts the solutions.
