    Sammanfattning : Transportation, together with transportation planning for goods, provides good conditions for economic growth and is a natural part of modern society. However, transportation has negative side effects, including emissions and traffic congestion. LÄS MER

  5. 4. Decomposition Methods for Combinatorial Optimization

    Författare :Uledi Ngulo; Torbjörn Larsson; Nils-Hassan Quttineh; Egbert Mujuni; Athanasios Migdalas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis aims at research in the field of combinatorial optimization. Problems within this field often posses special structures allowing them to be decomposed into more easily solved subproblems, which can be exploited in solution methods. These structures appear frequently in applications. LÄS MER

  7. 5. Methods for Network Optimization and Parallel Derivative-free Optimization

    Författare :Per-Magnus Olsson; Kaj Holmberg; Athanasios Migdalas; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Derivative-free; parallelization; Steiner tree; constrained shortest path; unmanned aerial vehicles;

    Sammanfattning : This thesis is divided into two parts that each is concerned with a specific problem.The problem under consideration in the first part is to find suitable graph representations, abstractions, cost measures and algorithms for calculating placements of unmanned aerial vehicles (UAVs) such that they can keep one or several static targets under constant surveillance.
