A method for estimation of equivalent-volume ice thickness based on WMO egg code in absence of ridging parameters
Milakovic, Aleksandar-Sasa; Schütz, Peter; Piehl, Henry Peter; Ehlers, Sören (Journal article; Peer reviewed, 2018)When calculating equivalent-volume ice thickness along a vessel's projected route for the purpose of ice resistance estimation, information on both undeformed ice (level ice) and deformed ice (mainly ridges) is needed. ... -
Allocating Sales in the Farming of Atlantic Salmon: Maximizing Profits Under Uncertainty
Hæreid, Martin Bergan (Master thesis, 2011)Salmon farmers face an uncertain production environment and considerable price volatility, making planning a vital success criteria. This thesis describes the sources of uncertainty that are most important when planning ... -
An Evolutionary Algorithm for Waste Collection in Complex City Environments
Vigerust, Sondre Lerum; Mossige, Dag Coll (Master thesis, 2018)As the population of the world is in rapid growth and economic development leads to larger rates of consumption, the field of waste management is growing ever more important. This thesis is based on the waste collection ... -
Combining Optimization and Simulation for Designing a Robust Short-sea Feeder Network
Medbøen, Carl Axel Benjamin; Holm, Magnus Bolstad; Msakni, Mohamed Kais; Fagerholt, Kjetil; Schütz, Peter (Peer reviewed; Journal article, 2020)Here we study a short-sea feeder network design problem based on mother and daughter vessels. The main feature of the studied system is performing transshipment of cargo between mother and daughter vessels at appropriate ... -
Current status and future operational models for transit shipping along the Northern Sea Route
Milakovic, Aleksandar-Sasa; Gunnarsson, Bjørn; Balmasov, Sergey; Hong, Sungwon; Kim, Kitae; Schütz, Peter; Ehlers, Sören (Journal article; Peer reviewed, 2018)The Northern Sea Route (NSR) has received increased international attention during the recent years as an alternative transit corridor for shipping between Europe and East Asia. In 2015, the project “Feasibility and ... -
Decarbonizing the Norwegian fishery fleet – strategic fleet renewal with environmental considerations
Sønnervik, Helle Hagli; Msakni, Mohamed Kais; Schütz, Peter (Journal article; Peer reviewed, 2024)This study addresses the pressing need for the Norwegian fishery sector to align with national reduction targets and mitigate its environmental impact. Norway has committed to reducing GHG emissions from the fishery sector ... -
Designing the Hydrogen Supply Chain for Maritime transportation in Norway
Stadlerova, Sarka; Schütz, Peter (Peer reviewed; Journal article, 2021)We study the problem of locating hydrogen facilities for the maritime transportation sector in Norway. We present a multi-period model with capacity expansion to obtain optimal investment and expansion decisions and to ... -
From Tactical to Operational Routes in a Grocery Supply Chain - Quantifying the Impact of Increased Information Sharing Between a Wholesaler and a Transport Company
Goldsack, Madeleine; Celius, Ebba (Master thesis, 2018)In this thesis, we quantify the value of information sharing between a wholesaler and a transport company in the Norwegian grocery supply chain. Particularly, we investigate whether sharing of information at an earlier ... -
Impact of Production Technology Flexibility in a Multi-horizon Stochastic Hydrogen Facility Location Problem
Refsdal, Ivar; Sindre, Tobias Spinnangr (Master thesis, 2023)Hydrogen presenterer en spennende mulighet som et nullutslippsdrivstoff, spesielt for tungtransport og langtransportkjøretøyer. Dette potensialet gjør det til en nøkkelspiller i reduksjonen av Norges klimagassutslipp. I ... -
