• A model for optimal fleet composition of vessels for offshore wind farm maintenance 

      Gutierrez-Alcoba, Alejandro; Ortega, Gloria; Hendrix, Eligius M.T.; Halvorsen-Weare, Elin Espeland; Haugland, Dag (Journal article; Peer reviewed, 2017)
      We present a discrete optimisation model that chooses an optimal fleet of vessels to support maintenance operations at Offshore Wind Farms (OFWs). The model is presented as a bi-level problem. On the first (tactical) level, ...
    • Modelling overfow using mixed integer programming in short‑term hydropower scheduling 

      Litlabø, Tormod; Aaslid, Per; Riise, Tarjei Lid; Haugland, Dag (Peer reviewed; Journal article, 2023)
      Short-term hydropower scheduling seeks to find a production schedule that maximizes profit, but must also consider the hydrological balance and risk of overflow. Overflow is by nature a non-linear and non-convex phenomenon. ...
