  1. 1. Decision support tools for dynamic fleet management : applications in airline planning and ambulance logistics

    Författare :Tobias Andersson; Andrew J Mason; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In this work, decision support tools for dynamic fleet management problems are developed. The operational management tasks include dispatching, supervising and sometimes reconstructing the vehicle schedule. These tasks are often complex, while the time available to complete them is short.

  3. 2. The Tail Assignment Problem

    Författare :Mattias Grönkvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hybrid optimization; fleet planning; aircraft routing; column generation; airline optimization; tail assignment; constraint programming;

    Sammanfattning : The Aircraft Assignment problem is the problem of assigning flights to aircraft in such a way that some operational constraints are satisfied, and possibly that some objective function is optimized.We propose an approach to aircraft assignment which captures all operational constraints, including minimum connection times, airport curfews, maintenance, and preassigned activities.

  4. 3. Planning and Operation of Demand-Side Flexibility

    Författare :Meng Song; Mikael Amelin; Alessandra Parisio; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Power systems are changing with growing penetration of non-dispatchable renewable generation and increased demand of electric energy. More generation, transmission or distribution capacities are needed to balance the varying production and higher consumption. Demand-side flexibility is a potential solutionto tackle those challenges. LÄS MER

  5. 4. Production scheduling and shipment planning at oil refineries : optimization based methods

    Författare :Jan A. Persson; Bjørn Nygreen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the oil refinery industry, companies need to have a high utilization of production, storage, and transportation resources to be competitive. This can only be achieved by proper planning The purpose of this thesis is to contribute to the development of optimization models and solution methods that support the scheduling and planning at refinery companies.
