  1. 1. Robust design Accounting for uncertainties in engineering

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :David Lönn; Linköpings universitet.; Linköpings universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; TECHNOLOGY Engineering mechanics Solid mechanics; TEKNIKVETENSKAP Teknisk mekanik Fastkroppsmekanik;

    Sammanfattning : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  2. 2. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning

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

    Författare :Rasmus Bokrantz; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; multicriteria optimization; robust optimization; Pareto optimality; Pareto surface approximation; Pareto surface navigation; intensity-modulated radiation therapy; volumetric-modulated arc therapy; intensity-modulated proton therapy; Optimering; flermålsoptimering; robust optimering; Paretooptimalitet; Paretofrontsapproximation; Paretofrontsnavigering; intensitetsmodulerad strålterapi; rotationsterapi; intensitetsmodulerad protonterapi;

    Sammanfattning : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. LÄS MER

  3. 3. Robust optimization of radiation therapy accounting for geometric uncertainty

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

    Författare :Albin Fredriksson; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated proton therapy; uncertainty; robust planning; setup error; range error; intensity-modulated radiation therapy; multicriteria optimization;

    Sammanfattning : Geometric errors may compromise the quality of radiation therapy treatments. Optimization methods that account for errors can reduce their effects.The first paper of this thesis introduces minimax optimization to account for systematic range and setup errors in intensity-modulated proton therapy.
