Optimizing Maritime Preparedness Under Uncertainty – Locating Tugboats Along the Norwegian Coast
Musæus, Julie Lovise; Nøstvik, Håkon M.; Andersson, Henrik; Schütz, Peter (Peer reviewed; Journal article, 2021)We study the strategic problem of locating tugboats along the Norwegian coast to optimize maritime preparedness. The problem is formulated as a two-stage stochastic program. In the first stage, we locate the tugboats such ... -
Planning Annual LNG Deliveries with Transshipment
Li, Mingyu; Schütz, Peter (Peer reviewed; Journal article, 2020)The introduction of transshipment ports in the liquefied natural gas (LNG) supply chain in recent years offers additional flexibility, but also challenges to the planning of the annual delivery program. We present a new ... -
Power Grid Inspection and Maintenance Optimization - A Stochastic Dynamic Programming Approach
Blaauw, Trym Haakon Andenes; Erikstad, Jakob (Master thesis, 2021)Denne masteroppgaven studerer operasjonsanalyse i kontekst av inspeksjon og vedlikehold av strømnettet. Den motiveres av potensialet for besparelser ved bruk av optimale inspeksjons- og vedlikeholdsbeslutninger. Problemet ... -
Production optimization in the salmon farming industry: Ordering smolt under uncertainty
Rynning-Tønnesen, Christine; Overaas, Sivert Thorvik (Master thesis, 2012)In the last decade the salmon farming industry has expanded rapidly and gone towards consolidation, thus the complexity of planning has increased. Therefore, the need for better planning tools has arisen. In this master ... -
Production Planning for Atlantic Salmon under Uncertainty with Impact of Extensive Site Management
Næss, Martin; Patricksson, Fredrik Selnes (Master thesis, 2019)Norwegian salmon production has expanded and then flattened over the past few years, due to strict regulatory requirements which limit the opportunity of increased production. However, new technological advances have ... -
Produksjonsoptimering innenfor lakseoppdretten - planlegging under usikkerhet
Langan, Tarald Bjørdal; Toftøy, Tor (Master thesis, 2011)Havbruksnæringen er en stor næring i Norge, og har opplevd store endringer i struktur og lovverk de siste årene. Sjøvanndelen av verdikjeden for oppdrettslaks har siden 2005 blitt regulert av et krav om maksimal tillatt ... -
Quantifying the Effect of Flexibility and Information Sharing in Transportation Planning
Celius, Ebba; Reehorst, Madeleine; Dreyer, Heidi Carin; Schütz, Peter (Peer reviewed; Journal article, 2020)In this paper, we analyze the effect of information sharing between a wholesaler and a transport company in the Norwegian grocery supply chain. The planning process of each company is formulated as a set covering problem, ... -
Shortsea Liner Network Design with Transhipments at Sea: A Case Study from Western Norway
Holm, Magnus Bolstad; Medbøen, Carl Axel Benjamin; Fagerholt, Kjetil; Schütz, Peter (Journal article; Peer reviewed, 2018)Short Sea Pioneer (SSP) is a novel concept for shortsea shipping. The concept is based on daughter ships acting as feeder vessels that meet with the mother ship at suitable locations at sea to tranship cargo. Such a system ... -
Sketching the Landscape for Lean Digital Transformation
Ashrafian, Alireza; Powell, Daryl; Ingvaldsen, Jonas A; Dreyer, Heidi Carin; Holtskog, Halvor; Schütz, Peter; Holmen, Elsebeth; Pedersen, Ann-Charlott; Lodgaard, Eirin Anita (Peer reviewed; Journal article, 2019)Lean management remains the most popular approach to operational excellence within industry. The next wave of industrial improvement is widely considered to be driven by the application of digital technologies. Organizations ... -
Solving a maritime inventory routing problem under uncertainty using optimization and simulation
Nikolaisen, Jørgen Bjaarstad; Vågen, Sofie Smith; Schütz, Peter (Peer reviewed; Journal article, 2023)The problem studied in this paper is inspired by one of the world’s largest producers of aluminium. The company produces alumina in South America that needs to be transported to aluminium production plants along the west ... -
Stochastic tramp ship routing with speed optimization: Analyzing the impact of the Northern Sea Route on CO2 emissions
Li, Mingyu; Fagerholt, Kjetil; Schütz, Peter (Peer reviewed; Journal article, 2022)To address the decarbonization challenge, we consider a tramp ship routing problem with speed optimization where the availability of future cargoes is uncertain. We propose a two-stage stochastic programming model to solve ... -
Strategic Fleet Renewal of Norwegian Fisheries with Environmental Considerations
Sønnervik, Helle Hagli (Master thesis, 2023)Norge har under Parisavtalen forpliktet seg til å redusere utslippene av klimagasser med minst 55% innen 2030 sammenliknet med utslippsnivået i 1990. I tillegg har Norge et lovfestet mål om å bli et lavutslippssamfunn innen ... -
