    • An integrated approach to tactical planning for the orthopaedic department at St. Olav's Hospital 

      Abdullahu, Anita (Master thesis, 2020)
      The regionale helseforetaket Helse Midt-Norge (HMN) er tilbyr sykehustjenester fylkene i Trøndelag og Møre og Romsdal i Norge. St. Olav's Hospital er per i dag det største sykehuset. Prognoser viser at innen de to fylkene ...

    • Decision-dependent probabilities in stochastic programs with recourse 

      Hellemo, Lars; Barton, Paul I.; Tomasgard, Asgeir (Journal article; Peer reviewed, 2018)
      Stochastic programming with recourse usually assumes uncertainty to be exogenous. Our work presents modelling and application of decision-dependent uncertainty in mathematical programming including a taxonomy of stochastic ...

    • Hydrogen for harvesting the potential of offshore wind: A North Sea case study 

      Bødal, Espen Flo; Holm, Sigmund Eggen; Rammohan Subramanian, Avinash Shankar; Durakovic, Goran; Pinel, Dimitri; Hellemo, Lars; Muñoz Ortiz, Miguel; Knudsen, Brage Rugstad; Straus, Julian (Peer reviewed; Journal article, 2024)
      Economical offshore wind developments depend on alternatives for cost-efficient transmission of the generated energy to connecting markets. Distance to shore, availability of an offshore power grid and scale of the wind ...

    • Managing Uncertainty in Design and Operation of Natural Gas Infrastructure 

      Hellemo, Lars (Doctoral thesis at NTNU;2016:128, Doctoral thesis, 2016)
      Summary of the thesis: This thesis concerns the management of uncertainty in design and operation of natural gas infrastructure by means of mathematical programming. The export of natural gas is an important industry in ...

    • Multi-horizon stochastic programming 

      Kaut, Michal; Midthun, Kjetil Trovik; Werner, Adrian; Tomasgard, Asgeir; Hellemo, Lars; Fodstad, Marte (Journal article; Peer reviewed, 2014)
      Infrastructure-planning models are challenging because of their combination of different time scales: while planning and building the infrastructure involves strategic decisions with time horizons of many years, one needs ...

    • Next frontiers in energy system modelling: A review on challenges and the state of the art 

      Fodstad, Marte; Crespo del Granado, Pedro; Hellemo, Lars; Knudsen, Brage Rugstad; Pisciella, Paolo; Silvast, Antti; Bordin, Chiara; Schmidt, Sarah; Straus, Julian (Peer reviewed; Journal article, 2022)
      Energy Systems Modelling is growing in relevance on providing insights and strategies to plan a carbon-neutral future. The implementation of an effective energy transition plan faces multiple challenges, spanning from the ...

    • Optimal vaksinasjonsstrategi ved en influensapandemi 

      Njøten, Hilde Kristin (Master thesis, 2014)
      Denne masteroppgaven presenterer og drøfter ulike optimeringsmodeller som skal fungere som et beslutningsverktøy i forbindelse med valg av vaksinasjons- og håndteringsstrategier ved en kommende pandemi i Norge. Modellene ...

    • 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 ...

    • Studie av optimal vaksinasjonsstrategi ved bruk av stokastisk optimering 

      Skogen, Camilla Marie; Lunden, Christine Leine (Master thesis, 2014)
      Dette arbeidet presenterer hvordan ulike optimeringsmodeller kan bidra til å finne en optimal vaksinasjonsstrategi som minimerer de samfunnsøkonomiske kostnadene ved et eventuelt utbrudd av influensapandemi i Norge. Modellene ...

    • Uncertainty and Cancellations in Advance Surgery Scheduling: An Exact Pattern-Based Solution Approach for Large-Scale Problems applied in a Rolling Horizon Simulation 

      Schiøtz, Mats Ingesen; Tysse, Jostein Hjortland (Master thesis, 2023)
      St. Olavs hospital, Midt-Norges største helseinstitusjon, forventer en økning i etterspørsel på 35 % for kirurgiske inngrep grunnet demografiske endringer. Mangelen på helsepersonell og ressurser gjør effektiv operasjons ...
