• Analyzing passing networks in association football based on the difficulty, risk, and potential of passes 

      Wiig, Astrid Salte; Håland, Else Marie; Stålhane, Magnus; Hvattum, Lars Magnus (Peer reviewed; Journal article, 2019)
      This paper investigates the use of network analysis to identify key players on teams, and patterns of passing within teams, in association football. Networks are constructed based on passes made between players, and ...
    • Evaluating passing ability in association football 

      Håland, Else Marie; Wiig, Astrid Salte; Stålhane, Magnus; Hvattum, Lars Magnus (Peer reviewed; Journal article, 2020)
      In this paper, the passing ability of football players is determined by building three generalized additive mixed models that each explains a different aspect of a pass’ success: difficulty, risk and potential. The models ...
    • Evaluating the effectiveness of different network flow motifs in association football 

      Håland, Else Marie; Wiig, Astrid Salte; Hvattum, Lars Magnus; Stålhane, Magnus (Peer reviewed; Journal article, 2020)
      In association football, a network flow motif describes how distinct players from a team are involved in a passing sequence. The flow motif encodes whether the same players appear several times in a passing sequence, and ...
    • In-game betting and the Kelly criterion 

      Andersen, Robin; Hassel, Vegard; Hvattum, Lars Magnus; Stålhane, Magnus (Peer reviewed; Journal article, 2020)
      When a bet with a positive expected return is available, the Kelly criterion can be used to determine the fraction of wealth to wager so as to maximize the expected logarithmic return on investment. Several variants of the ...
    • New benchmark instances for the inventory routing problem 

      Skålnes, Jørgen; Ben Ahmed, Mohamed; Hvattum, Lars Magnus; Stålhane, Magnus (Peer reviewed; Journal article, 2024)
      The existing sets of benchmark instances for the inventory routing problem (IRP) have been beneficial for investigating and illustrating the properties of the problem. However, they possess certain features and design ...
    • 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 (Peer reviewed; Journal article, 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 ...
    • 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 (Peer reviewed; Journal article, 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 ...
