  1. 1. Cost Optimization of Aircraft Structures

    Detta är en avhandling från Stockholm : KTH

    Författare :Markus Kaufmann; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aircraft structures; optimization; cost estimation; manufacturing cost; direct operating cost; multiobjective optimization; multidisciplinary optimization; composites; airframe design; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Sammanfattning : Composite structures can lower the weight of an airliner significantly. Due to the higher process complexity and the high material cost, however, the low weight often comes with a significant increase in production cost. The application of cost-effective design strategies is one mean to meet this challenge. LÄS MER

  3. 2. Composition and Optimization

    Detta är en avhandling från Växjö : Växjö University Press

    Författare :Morgan Ericsson; Växjö universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; software composition; software reuse; optimization; high-performance computing; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Sammanfattning : A recent trend in software engineering is to delay design decisions. One motivation is that requirements or properties of the application and environment are not known until later in the design and development process. This continues to hold for design decisions in a high-performance context where e.g. LÄS MER

  4. 3. 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

  5. 4. Combinatorial Optimization Three Applications

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Efraim Laksman; Blekinge Tekniska Högskola.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Combinatorial optimization is a diverse area of mathematics. It concerns optimization on feasible regions defined by discrete sets, graphs, hypergraphs, matroids, etc. . . LÄS MER

  7. 5. A bilevel approach to parameter tuning of optimization algorithms using evolutionary computing : Understanding optimization algorithms through optimization

    Detta är en avhandling från Skövde : University of Skövde

    Författare :Martin Andersson; Högskolan i Skövde.; Högskolan i Skövde.; [2018]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Most optimization problems found in the real world cannot be solved using analytical methods. For these types of difficult optimization problems, an alternative approach is needed. LÄS MER
