    • Playing Style and Performance in Association Football: How to Invest Smarter 

      Bosnjak, Una; Vigerust, Olav Lund (Master thesis, 2022)
      Datadrevne metoder blir stadig viktigere for å oppnå innsikt i europeisk fotball. Målet med denne oppgaven er å utforske hvordan fotballklubber kan forbedre prestasjonene sine; dette gjennomføres ved å kombinere domenekunnskap ...

    • Robust Optimization for a Maritime Inventory Routing Problem 

      Agra, Agostinho; Christiansen, Marielle; Hvattum, Lars Magnus; Rodrigues, Filipe (Journal article; Peer reviewed, 2018)
      We consider a single product maritime inventory routing problem in which the production and consumption rates are constant over the planning horizon. The problem involves a heterogeneous fleet and multiple production and ...

    • Scheduling of maintenance tasks and routing of a joint vessel fleet for multiple offshore wind farms 

      Raknes, Nora Tangen; Ødeskaug, Katrine; Stålhane, Magnus; Hvattum, Lars Magnus (Journal article; Peer reviewed, 2017)
      Maintenance costs related to offshore wind farms are severely limiting their potential for being profitable. This paper proposes a new mathematical model that considers how maintenance tasks should be scheduled and performed ...

    • Subsea investments and well placements in the oil production industry 

      Haug, Eirik Røysem (Master thesis, 2013)
      Strengere krav fra myndigheter og en økende mengde aldrende olje- og gassfelt krever en stadig høyere utvinningsgrad for å gjøre feltene, og reservoarene lønnsomme. Dette prosjektet tester optimeringsmetoder i kombinasjon ...

    • The robust vehicle routing problem with time windows 

      Agra, Agostinho; Christiansen, Marielle; Figueiredo, Rosa; Hvattum, Lars Magnus; Poss, Michael; Requejo, Cristina (Journal article; Peer reviewed, 2013)
      This paper addresses the robust vehicle routing problem with time windows. We are motivated by a problem that arises in maritime transportation where delays are frequent and should be taken into account. Our model only ...

    • Valuing Individual Player Involvements in Norwegian Association Football 

      Nørstebø, Olav; Bjertnes, Vegard Rødseth; Vabo, Eirik (Master thesis, 2016)
      Evaluation of player performance in association football has to a large extent been limited to subjective opinions and simple, easily observable parameters such as goals, passing accuracy and ball recoveries. In this thesis, ...

    • Vessel fleet analysis for maintenance operations at offshore wind farms 

      Halvorsen-Weare, Elin Espeland; Gundegjerde, Christian; Halvorsen, Ina Blomseth; Hvattum, Lars Magnus; Nonås, Lars Magne (Journal article; Peer reviewed, 2013)
      Performing maintenance operations at offshore wind farms involves one major challenge compared with the onshore counterpart: All maintenance personnel and spare parts need to be transported from an onshore port or offshore ...

    • Vessel Fleet Optimization for Maintenance Operations at Offshore Wind Farms under Uncertainty 

      Stålhane, Magnus; Vefsnmo, Hanne; Halvorsen-Weare, Elin Espeland; Hvattum, Lars Magnus; Nonås, Lars Magne (Journal article; Peer reviewed, 2016)
      In this paper we consider the problem of determining the optimal fleet size and mix of vessels to support maintenance activities at offshore wind farms. A two-stage stochastic programming model is proposed where uncertainty ...

    • Vessel fleet size and mix for maintenance of offshore wind farms: A stochastic approach 

      Gundegjerde, Christian; Halvorsen, Ina Blomseth (Master thesis, 2012)
      In recent years the global installed capacity of offshore wind has increased rapidly, due to the world’s green electricity demand. Increasing developments in the offshore wind sector has led to fewer possible locations for ...
