    • A bridge between continuous and discrete-time bioeconomic models: Seasonality in fisheries 

      Kvamsdal, Sturla F; Maroto, Jose M.; Moran, Manuel; Sandal, Leif Kristoffer (Journal article; Peer reviewed, 2017)
      We develop a discretization method to construct a discrete finite-time bioeconomic model, corresponding to bioeconomic models with continuous-time growth function, but allowing the analysis of seasonality in fisheries. The ...

    • An analysis of maintenance schedules for public facilities 

      Hopland, Arnt Ove; Kvamsdal, Sturla F; Sandal, Leif Kristoffer (Journal article; Peer reviewed, 2019)
      We present a flexible, formal framework for maintenance scheduling for public facilities. Key features of the model include an accelerating deterioration scheme, a general utility measure, and real estate market effects ...

    • Construction of Equilibria in Strategic Stackelberg Games in Multi-Period Supply Chain Contracts 

      Azad Gholami, Reza; Sandal, Leif Kristoffer; Ubøe, Jan (Peer reviewed; Journal article, 2022)
      Almost every supplier faces uncertain and time-varying demand. E-commerce and online shopping have given suppliers unprecedented access to data on customers’ behavior, which sheds light on demand uncertainty. The main ...

    • Harvest control rules in modern fisheries management 

      Kvamsdal, Sturla F; Eide, Arne; Ekerhovd, Nils-Arne; Enberg, Katja; Gudmundsdottir, Asta; Hoel, Alf Håkon; Mills, Katherine E.; Mueter, Franz J.; Ravn-Jonsen, Lars; Sandal, Leif Kristoffer; Stiansen, Jan Erik; Vestergaard, Niels (Journal article; Peer reviewed, 2016)
      Harvest control rules have become an important tool in modern fisheries management, and are increasingly adopted to provide continuity in management practices, to deal with uncertainty and ecosystem considerations, and to ...

    • Harvesting in a Fishery with Stochastic Growth and a Mean-Reverting Price 

      Kvamsdal, Sturla F; Poudel, Diwakar; Sandal, Leif Kristoffer (Journal article; Peer reviewed, 2014)
      We analyze a continuous, nonlinear bioeconomic model to demonstrate how stochasticity in the growth of fish stocks affects the optimal exploitation policy when prices are stochastic, mean-reverting and possibly harvest ...

    • Stochastically Induced Critical Depensation and Risk of Stock Collapse 

      Poudel, Diwakar; Sandal, Leif Kristoffer; Kvamsdal, Sturla F (Peer reviewed; Journal article, 2015)

    • The Ensemble Kalman Filter for Multidimensional Bioeconomic Models 

      Kvamsdal, Sturla F; Sandal, Leif Kristoffer (Peer reviewed; Journal article, 2015)

    • Who benefits from postponement in multi-period supply channel optimization? 

      Azad Gholami, Reza; Sandal, Leif Kristoffer; Ubøe, Jan (Peer reviewed; Journal article, 2023)
      Duopolistic price-setting supply channels competing in a bilevel framework have been extensively studied in single-period (static) settings. However, such supply channels typically face uncertain and time-varying demand; ...
