On equivalent ice thickness and machine learning in ship ice transit simulations
Milaković, Aleksandar-Saša (Doctoral theses at NTNU;2019:377, Doctoral thesis, 2019)This thesis presents a contribution to the research field of ship ice transit simulations used for estimating the ship resistance/speed profile in a complex ice field. Namely, two distinct methodological approaches within ... -
Operational production planning for multi-plant metal casting using mixed integer linear programming - A case study from the aluminum industry
Reine, Marianne Grødem; Wilsher, Håvard; Ullebust, Thea Sofie Narvestad (Master thesis, 2018)Significant market shares in the global aluminum industry belong to producers located in low cost countries. Norsk Hydro ASA is a Norwegian firm in this industry, and operate as a Make-to-Order company. They deliver cast ... -
Optimal hedging strategies for salmon producers
Schütz, Peter; Westgaard, Sjur (Journal article; Peer reviewed, 2018)We study the optimal hedging decisions for a risk-averse salmon producer. The hedging decisions are determined using a multistage stochastic programming model. The objective is to maximize the weighted sum of expected ... -
Optimal Investment and Operation Strategy for Oil Spill Preparedness: With Case Study on the Northern Norwegian Continental Shelf
Walslag, Hilde Løset; Høyland, Tonje (Master thesis, 2013)The development of petroleum activities in the northern area has brought an increased focus on developing offshore oil spill preparedness. Remoteness and harshclimate dominating large parts of the region pose new challenges ... -
