  2. 16. Improved Frank-Wolfe directions with applications to traffic problems

    Author : Maria Daneva (Mitradjieva); Jonas Eliasson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The main contribution of this thesis is the development of some new efficient algorithms for solving structured linearly constrained optimization problems. The conventional Frank-Wolfe method is one of the most frequently used methods for solving such problems. READ MORE

  4. 17. Models and methods for school timetabling using a column generation approach

    Author : Patrik Eveborn; Krister Svanberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Creating timetables for educational institutions is a complex task, and the quality of the timetables affects a large number of students and teachers. This process involves assigning teachers to courses, students to classes, classrooms to lessons and setting the starting time of the lessons. READ MORE

  5. 18. Optimization approaches to tactical planning problems in the forest industry

    Author : Helene Gunnarsson; Ola Eriksson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : By using decision support tools based on operations research (OR) and optimization in the supply chain in the forest industry, the planning process can be improved and higher profitability can be obtained. The focus of this thesis is on modelling two real-life problems. READ MORE

  6. 19. Ring network design in telecommunications : optimization based solution approaches

    Author : Mathias Henningsson; Jens Clausen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Abstract : When designing a telecommunication network, one often wish to include some kind of survivability requirement, for example that the network should be two-connected. A two-connected network fulfills the requirement that there should be at least two paths with no links in common between all pairs of nodes. READ MORE

  7. 20. Mathematical Optimization of HDR Brachytherapy

    Author : Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Jeroen Beliën; Linköpings universitet; []
    Keywords : ;

    Abstract : One out of eight deaths throughout the world is due to cancer. Developing new treatments and improving existing treatments is hence of major importance. In this thesis we have studied how mathematical optimization can be used to improve an existing treatment method: high-dose-rate (HDR) brachytherapy. READ MORE
