  1. 1. Mixed-Integer Optimization Modeling for the Simultaneous Scheduling of Component Replacement and Repair

    Författare :Gabrijela Obradovic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical Modeling; Workshop Scheduling; Maintenance Optimization; Simultaneous Scheduling; Mixed-Integer Linear Optimization; Multi-Objective Optimization; Contracting Forms;

    Sammanfattning : Maintenance is a critical aspect of many industries, playing an indispensable role in ensuring the optimal functionality, reliability, and longevity of various assets, equipment, and infrastructure. For a system to remain operational, maintenance of its components is required, and for the industry to optimize its operations, establishment of good maintenance policies and practices is vital.

  3. 2. On Models and Methods for Global Optimization of Structural Topology

    Författare :Mathias Stolpe; KTH; []
    Nyckelord :topology optimization; global optimization; stress constraints; linear programming; mixed integer programming; branch-and-bound;

    Sammanfattning : This thesis consists of an introduction and sevenindependent, but closely related, papers which all deal withproblems in structural optimization. In particular, we considermodels and methods for global optimization of problems intopology design of discrete and continuum structures. 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. 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

  7. 5. Applications of Integer Quadratic Programming in Control and Communication

    Författare :Daniel Axehill; Anders Hansson; Anders Rantzer; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Model Predictive Control; CDMA; Quadratic Programming; Mixed Integer Quadratic Programming; Dual active set methods; Riccati recursion; Branch and bound; 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 principles is the discrete-time method Model Predictive Control (MPC). LÄS MER
