    • Adaptive large neighborhood search heuristics for multi-tier service deployment problems in clouds 

      Gullhav, Anders Nordby; Cordeau, Jean-Francois; Hvattum, Lars Magnus; Nygreen, Bjørn (Journal article; Peer reviewed, 2016)
      This paper proposes adaptive large neighborhood search (ALNS) heuristics for two service deployment problems in a cloud computing context. The problems under study consider the deployment problem of a provider of ...

    • An effective heuristic for solving a combined cargo and inventory routing problem in tramp shipping 

      Hemmati, Ahmad; Stålhane, Magnus; Hvattum, Lars Magnus; Andersson, Henrik (Journal article; Peer reviewed, 2015)
      In this paper a vendor managed inventory (VMI) service in tramp shipping is considered. VMI takes advantage of introducing flexibility in delivery time and cargo quantities by transferring inventory management and ordering ...

    • Analyzing and Predicting Performances and Playing Styles of Football Players 

      Gundersen, Lars Hegg; Kim, Markus Malum; Strobel, Eliot Karlsen (Master thesis, 2022)
      Interessen rundt utnyttelse av dataanalyse som konkurransefortrinn i fotballen er økende, noe som gjenspeiles gjennom stadig flere publiserte artikler. Arbeidet i denne masteroppgaven er sentrert rundt modeller utviklet ...

    • 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 (Journal article; Peer reviewed, 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, ...

    • Benchmark Suite for Industrial and Tramp Ship Routing and Scheduling Problems 

      Hemmati, Ahmad; Hvattum, Lars Magnus; Fagerholt, Kjetil; Norstad, Inge (Journal article; Peer reviewed, 2014)
      This paper considers a class of cargo ship routing and scheduling problems from industrial and tramp shipping and presents a wide range of benchmark instances that have been created to represent realistic planning problems ...

    • Composing vessel fleets for maintenance at offshore wind farms by solving a dual-level stochastic programming problem using GRASP 

      Bolstad, Kamilla Hamre; Joshi, Manu; Hvattum, Lars Magnus; Stålhane, Magnus (Peer reviewed; Journal article, 2022)
      Background: Dual-level stochastic programming is a technique that allows modelling uncertainty at two different levels, even when the time granularity differs vastly between the levels. In this paper we study the problem ...
