    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; multiple objectives; platform-based products; heavy-duty trucks; configuration management; categorical variables; global optimization; robustness; categorical variables; multiple objectives; platform-based products; global optimization; robustness; configuration management; heavy-duty trucks;

    Sammanfattning : The optimal truck configuration for a certain customer is very specific and depends on for what transport mission and in which operating environment the truck is to be used. In addition, the customers normally specify other feature requirements ranging from visual appearance to advanced driver support systems. LÄS MER

  4. 4. Approximation of topology optimization problems using sizing optimization problems

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Anton Evgrafov; Göteborgs universitet.; Gothenburg University.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; structural optimization; bilevel programming; approximation; topology optimization; control in coefficients; optimal design; fictitious domain; control in coefficients; bilevel programming; optimal design; topology optimization; fictitious domain; approximation;

    Sammanfattning : The present work is devoted to approximation techniques for singular extremal problems arising from optimal design problems in structural and fluid mechanics. The thesis consists of an introductory part and four independent papers, which however are united by the common idea of approximation and the related application areas. LÄS MER

  5. 5. Toward Robust Optimization of Adaptive Radiation Therapy

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Michelle Böck; Anders Forsgren; Minsun Kim; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimization; adaptive radiation therapy; radiation therapy treatment planning; uncertainty; robust optimization; stochastic programming; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : Adaptive radiation therapy is an evolving cancer treatment approach which relies on adapting the treatment plan in response to patient-specific interfractional geometric variations occurring during the fractionated treatment. If those variations are not addressed through adaptive replanning, the resulting treatment quality may be compromised. LÄS MER
