• A Bellman approach to periodic optimization problems 

      Kvamsdal, Sturla F.; Maroto, José M.; Morán, Manuel; Sandal, Leif K. (Discussion paper;19/16, Working paper, 2016-11-30)
      We consider an infinite horizon optimization problem with arbitrary but finite periodicity in discrete time. The problem can be formulated as a fix-point problem for a contraction operator, and we provide a solution scheme ...
    • Backhauling in forest transportation : models, methods and practical usage 

      Carlsson, Dick; Rönnqvist, Mikael (Discussion paper, Working paper, 2006)
      Transportation planning in forestry is divided into strategic, tactical and operational depending on the length of the planning horizon. We consider a tactical problem of finding efficient backhauling routes. Given a set ...
    • Interview Scheduling: An Integer Programming Approach 

      Braathen, Christian (Discussion paper;10/22, Working paper, 2022-04-21)
      This article provides a general meeting scheduling model to schedule en-masse interviews over multi-day events. Creating such meeting schedules is a complicated, time-consuming task that usually requires considerable manual ...
    • Optimization of age-structured bioeconomic model: recruitment, weight gain and environmental effects 

      Ni, Yuanming (Discussion paper;4/19, Working paper, 2019-09-03)
      More and more fishery researchers begin to acknowledge that one-dimensional biomass models may omit key information when generating management guidelines. For the more complicated age-structured models, numerous parameters ...
