    • A Memetic Algorithm With Optimal Quantity Assignments for the Fish Feed Maritime Inventory Routing Problem 

      Bjelland, Anders; Borgen, Aksel; Wold, Sjur (Master thesis, 2022)
      Oppdrettslaks er en av Norges mest verdifulle eksportvarer. Mindre kjent er fiskefôrindustrien som daglig produserer og distribuerer omtrent 5.000 tonn fôr til anlegg langs hele norskekysten. Lave profittmarginer gjør ...

    • A two-phase heuristic for an in-port ship routing problem with tank allocation 

      Wang, Xin; Arnesen, Mari Jevne; Fagerholt, Kjetil; Gjestvang, Magnhild; Thun, Kristian (Journal article; Peer reviewed, 2017)
      This paper addresses an in-port ship routing problem with tank allocation that arises in the chemical shipping industry. The aim is to optimize a tanker’s port call operation that integrates sequencing decisions for visiting ...

    • A Branch-and-Price Algorithm for the Liner Shipping Network Design Problem 

      Thun, Kristian; Andersson, Henrik; Stålhane, Magnus (Peer reviewed; Journal article, 2020)
      Maritime transportation is the backbone of the global economy and one of its most important segments is liner shipping. To design a liner shipping network is notoriously difficult but also very important since an efficient ...

    • The Fish Feed Production Routing Problem 

      Brekkå, Ivar; Randøy, Solveig; Fagerholt, Kjetil; Thun, Kristian; Vadseth, Simen Tung (Peer reviewed; Journal article, 2022)
      This paper introduces the fish feed production routing problem (FFPRP) faced by Norwegian salmon feed producers. The FFPRP is comprised of a production scheduling problem and a rich vehicle routing problem (VRP) and thus ...

    • Methods and concepts for OR for autonomy in small ports 

      Halvorsen-Weare, Elin Espeland; Ahmed, Mohamed Ben; Kisialiou, Yauheni; Nafstad, Gaute Messel; Thun, Kristian (Research report, 2024)
      This report provides an overview of methods and concepts in operational research applied to autonomy in small ports. A literature review has been conducted and is presented, along with suggestions for methods and concepts ...

    • A new formulation for the liner shipping network design problem 

      Ameln, Marie; Fuglum, Julie Sand; Thun, Kristian; Andersson, Henrik; Stålhane, Magnus (Peer reviewed; Journal article, 2019)
      The liner shipping network design problem (LSNDP) is an important problem within liner shipping because a good network can reduce costs and increase profits. Given sets of ports, vessel classes, and demands between the ...

    • Optimization of routing and scheduling problems in liner shipping 

      Thun, Kristian (Doctoral theses at NTNU;2020:284, Doctoral thesis, 2020)

    • Robust route design for vehicle routing problems with stochastic customer demand 

      Kulås, Arnt-Ove; Thun, Kristian (Master thesis, 2009)

    • Routing and tank allocation for a chemical tanker 

      Gjestvang, Magnhild; Arnesen, Mari Jevne (Master thesis, 2015)
      This thesis considers a chemical tanker arriving a port with several terminals where customers are to be served. The customers have both pickup and delivery requirements, and the intention is to find a feasible route for ...
