  1. 1. Ride Comfort Optimization of Buses

    Författare :Peter Eriksson; [2002]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural vibrations; FEM; global optimization; ride comfort; roll control system; MBS; optimization; bus; road irregularities; sensitivity analysis;

    Sammanfattning : As the design of buses is constantly improving, passengers are becoming more fastidious and the demand for a more comfortable travelling environment is constantly increasing. The main objective of this thesis is to contribute to the understanding of how the design of buses affects the ride comfort characteristics. LÄS MER

  2. 2. Product Configuration from a Mathematical Optimization Perspective

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Peter Lindroth; Göteborgs universitet.; Gothenburg University.; [2011]
    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

  3. 3. On Models and Methods for Global Optimization of Structural Topology

    Detta är en avhandling från Stockholm : Matematik

    Författare :Mathias Stolpe; [2003]
    Nyckelord :topology optimization; global optimization; stress constraints; linear programming; mixed integer programming; branch-and-bound;

    Sammanfattning : This thesis consists of an introduction and sevenindependent, but closely related, papers which all deal withproblems in structural optimization. In particular, we considermodels and methods for global optimization of problems intopology design of discrete and continuum structures. LÄS MER

  4. 4. Small-Scale Decentralized Energy Systems optimization and performance analysis

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Sammanfattning : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. LÄS MER

  5. 5. Algorithms for Costly Global Optimization

    Detta är en avhandling från Västerås : Mälardalens högskola

    Författare :Nils-Hassan Quttineh; Kenneth Holmström; Hans Bruun Nielsen; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS Applied mathematics Optimization; systems theory; MATEMATIK Tillämpad matematik Optimeringslära; systemteori; Mathematics Applied Mathematics; Matematik tillämpad matematik;

    Sammanfattning : There exists many applications with so-called costly problems, which means that the objective function you want to maximize or minimize cannot be described using standard functions and expressions. Instead one considers these objective functions as ``black box'' where the parameter values are sent in and a function value is returned. LÄS MER
