  1. 21. Optimization of empty freight car distribution in scheduled railways

    Författare :Martin Joborn; Warren B. Powell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In a railway system, empty freight cars have to be repositioned to enable transportation demand to be fulfllled. These empty car movements are planned and implemented in the empty freight car distribution process. LÄS MER

  3. 22. Optimization models and methods for harvest planning and forest road upgrading

    Författare :Jenny Karlsson; David Martell; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : The purpose of this thesis is to contribute to the development and the use of optimization models and methods to support efficient decision making in Swedish forestry. The main problem areas concerned are forest road upgrade planning and operational harvest planning. Today much of the planning is done manually by experienced managers. LÄS MER

  4. 23. Effect Oriented Planning in Military Mission Support Systems : Models and Heuristic Approaches

    Författare :Kristian Lundberg; Kaj Holmberg; Torbjörn Larsson; Stefan Engevall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Today there are many aspects of model based planning, probably much more than for just 20 years ago. Today data is not the problem, data is everywhere, but the big issue is to understand how to gain advantage of data in decision making - a growing focus is now on modeling!This work is devoted to this task and can be seen as a three part study.

  5. 24. Optimization modelling and methods for freight transportation in scheduled railways

    Författare :Kennet Melin; Peter Värbrand; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the planning process of a freight railway transportation company, a number of optimization problems arise. In this thesis, we study two of them; empty freight car distribution and line planning. LÄS MER

  7. 25. Term structure estimation based on a generalized optimization framework

    Författare :Marcel Ndengo Rugengamanzi; Torbjörn Larsson; Jörgen Blomvall; Kristoffer Hägglöf; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The current work is devoted to estimating the term structure of interest rates based on a generalized optimization framework. To x the ideas of the subject, we introduce representations of the term structure as they are used in nance: yield curve, discount curve and forward rate curve. LÄS MER
