  1. 6. Methods and Applications in Integer Programming : All-Integer Column Generation and Nurse Scheduling

    Författare :Elina Rönnberg; Torbjörn Larsson; Fredrik Altenstedt; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integer programming; column generation; set partitioning problems; quasi-integrality; nurse scheduling; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : Integer programming can be used to provide solutionsto complex decision and planning problems occurring in a wide varietyof situations. Applying integer programming to a real life problembasically involves a first phase where a mathematical model isconstructed, and a second phase where the problem described by themodel is solved.

  3. 7. Mathematical Optimization Models and Methods for Open-Pit Mining

    Författare :Henry Amankwah; Torbjörn Larsson; Björn Textorius; Alexandra Newman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them, and in this process a deeper and deeper pit is formed until the mining operation ends. Mining is often a highly complex industrial operation, with respect to both technological and planning aspects. LÄS MER

  4. 8. Computation of Thermal Development in Injection Mould Filling, based on the Distance Model

    Författare :Per-Åke Andersson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermoplastic materials; finite element FEM ; finite difference FD ; Newton-Mysovskii theorem; Moldflow Mfl ; Cadmould Cmd ; MATHEMATICS; MATEMATIK;

    Sammanfattning : The heat transfer in the filling phase of injection moulding is studied, based on Gunnar Aronsson’s distance model for flow expansion ([Aronsson], 1996).The choice of a thermoplastic materials model is motivated by general physical properties, admitting temperature and pressure dependence.

  5. 9. Optimization of Financial Decisions using a new Stochastic Programming Method

    Författare :Jörgen Blomvall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The topics of this dissertation are the development of a new Stochastic Programming method and the application of Stochastic Programming in finance. Stochastic Programming is an area within Operations Research that has grown considerably over the last ten years. LÄS MER

  7. 10. Models and solution methods for large-scale industrial mixed integer programming problems

    Författare :David Bredström; Mikael Rönnqvist; Dag Wedelin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematic; linear programming MIP ; production-planning; MATHEMATICS; MATEMATIK;

    Sammanfattning : This thesis deals with large-scale industrial problems that can be formulated using mixed integer linear programming (MIP) models. Because of the large problem size, it is not often possible to apply standard solution methods. Therefore special techniques must be used. LÄS MER
