• A shortest-path-based approach for the stochastic knapsack problem with non-decreasing expected overfilling costs 

      Range, Troels Martin; Kozlowski, Dawid; Petersen, Niels Christian (Journal article; Peer reviewed, 2018)
      The knapsack problem (KP) is concerned with the selection of a subset of multiple items with known positive values and weights such that the total value of selected items is maximized and their total weight does not exceed ...
    • Decomposing bivariate dominance for social welfare comparisons 

      Marling, Tina Gottschalk; Range, Troels Martin; Sudhölter, Peter; Østerdal, Lars Peter (Journal article; Peer reviewed, 2018)
      The principal dominance concept for inequality-averse multidimensional social welfare comparisons, commonly known as lower orthant dominance, entails less or equal mass on all lower hyperrectangles of outcomes. Recently, ...
    • Dynamic job assignment: A column generation approach with an application to surgery allocation 

      Range, Troels Martin; Kozlowski, Dawid; Petersen, Niels Christian (Journal article; Peer reviewed, 2018)
      We consider the assignment of jobs to heterogeneous agents in a dynamic system with a rolling time horizon. An example is a hospital operating theatre where the jobs are surgeries and the agents are the surgeons. The paper ...
    • First-order dominance: stronger characterization and a bivariate checking algorithm 

      Range, Troels Martin; Østerdal, Lars Peter (Journal article; Peer reviewed, 2017)
      How to determine whether one distribution first-order dominates another is a fundamental problem that has many applications in economics, finance, probability theory, and statistics. Nevertheless, little is known about how ...
    • Stochastic master surgery scheduling 

      Bovim, Thomas; Christiansen, Marielle; Gullhav, Anders Nordby; Range, Troels Martin; Hellemo, Lars (Journal article; Peer reviewed, 2020)
      The aim of the Master Surgery Scheduling Problem (MSSP) is to schedule the medical specialties to the different operating rooms available, such that surgeries may be performed efficiently. We consider a MSSP where elective ...
    • Stochastic Master Surgery Scheduling for the orthopaedic department at St. Olav's Hospital 

      Bovim, Thomas Reiten (Master thesis, 2018)
      The regional health authority, Helse Midt-Norge (HMN), provides hospital services to the two counties Trøndelag and Møre og Romsdal. Forecasting estimates that the number of people living in these two counties that exceed ...
