  1. 1. Integer Quadratic Programming for Control and Communication

    Författare :Daniel Axehill; Anders Hansson; Manfred Morari; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integer Quadratic Programming; Model Predictive Control; Hybrid Systems; Semidefinite Programming; Code Division Multiple Access; Multiuser Detection; Automatic Control; Communication; Automatic control; Reglerteknik;

    Sammanfattning : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control methods is Model Predictive Control (MPC). In each sampling time, MPC requires the solution of a Quadratic Programming (QP) problem. LÄS MER

    Sammanfattning : The main topic of this thesis is integer quadratic programming with applications to problems arising in the areas of automatic control and communication. One of the most widespread modern control principles is the discrete-time method Model Predictive Control (MPC). LÄS MER

  4. 3. On the optimization of opportunistic maintenance activities

    Författare :Adam Wojciechowski; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixed integer linear programming; stochastic programming; complexity theory; mixed integer linear programming; complexity theory; stochastic programming;

    Sammanfattning : Maintenance is a source of large costs; in the EU the maintenance costs amountto between 4% and 8% of the total sales turnover. Opportunistic maintenance is anattempt to lower the maintenance cost by considering the failure of onecomponent as an opportunity to replace yet non-failed components in order toprevent future failures.

  5. 4. Haulage system optimization for underground mines : A discrete event simulation and mixed integer programming approach

    Författare :Abubakary Salama; Jazek Paraszczak; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : In coming decades, many underground mines will operate at greater depths, which will affect many operational factors such as increased rock stress, longer haulage distances, and higher energy consumption, which potentially can generate lower production rates. The increased rock stresses may lead to smaller sized openings, further restricting the size of loading and hauling equipment that can be used. LÄS MER

  7. 5. 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
