Zwaginga, J.J. (author), Lagemann, Benjamin (author), Erikstad, Stein Ove (author), Pruyn, J.F.J. (author)Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper investigates how methods that take uncertainty into account, like robust optimization and stochastic optimization, could be...journal article 2024

Gartland, Nicolas (author), Pruyn, J.F.J. (author)The design and preliminary estimations of biomass supply chains are essential in matching energy supply to energy demand. This is especially true of novel/future fuels and technologies in large industries. In this paper, a Mixed Integer Linear Programming (MILP) model was formulated to represent biofuel supply chains across Europe for the...journal article 2022

de Geus-Moussault, S.R.A. (author), Pruyn, J.F.J. (author), van der Voort, Esther (author), van IJserloo, Geert (author)Most ship management companies base the operational cost calculation on scheduled maintenance jobs. Scheduled maintenance jobs do not take unforeseen maintenance into account. This under-estimates the operational budget. The estimation of the operational costs can be improved by including the unforeseen maintenance costs. The amount of...conference paper 2020
