  1. 6. 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

  3. 7. Hierarchical Scheduling and Utility Disturbance Management in the Process Industry

    Författare :Anna Lindholm; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant-wide disturbances; utilities; production control; production scheduling; process industry; enterprise modeling; availability; receding horizon control;

    Sammanfattning : This thesis deals with control of production at large-scale process industrial sites in the presence of disturbances. The main focus is on disturbances in the supply of utilities such as steam, cooling water and electricity. LÄS MER

  4. 8. Energy and Route Optimization of Moving Devices

    Författare :Sarmad Riazi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy optimization; industrial robots; vehicle routing problems; automated guided vehicles.; scheduling; routing;

    Sammanfattning : This thesis highlights our efforts in energy and route optimization of moving devices. We have focused on three categories of such devices; industrial robots in a multi-robot environment, generic vehicles in a vehicle routing problem (VRP) context, automated guided vehicles (AGVs) in a large-scale flexible manufacturing system (FMS).

  5. 9. Enabling Technologies for Management of Distributed Computing Infrastructures

    Författare :Daniel Espling; Erik Elmroth; Rizos Sakellariou; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grid computing; cloud computing; accounting; billing; contextualization; monitoring; structure; fairshare; scheduling; federated; Computer Science; datalogi;

    Sammanfattning : Computing infrastructures offer remote access to computing power that can be employed, e.g., to solve complex mathematical problems or to host computational services that need to be online and accessible at all times. LÄS MER

  7. 10. Scheduling and Base-Station Cooperation in MIMO Downlink Systems

    Författare :Nima Seifi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Multiple input multiple output (MIMO) techniques have been shown to improvethe capacity and link reliability of wireless communication without a need to extrapower and bandwidth. In multi-user (MU) MIMO networks, a linear increaseof sum capacity in the number of transmit antennas can be achieved by usinglinear precoding combined with efficient scheduling algorithms. LÄS MER
