  1. 1. Lagrangian Bounding and Heuristics for Bi-Objective Discrete Optimisation

    Kandidat-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Ida Åkerholm; [2022]
    Nyckelord :Lagrangian relaxation; bi-objective optimisation; Pareto frontier; heuristics; discrete optimisation;

    Sammanfattning : For larger instances of multi-objective optimisation problems, the exact Pareto frontier can be both difficult and time-consuming to calculate. There is a wide range of methods to find feasible solutions to such problems, but techniques for finding good optimistic bounds to compare the feasible solutions with are missing. LÄS MER

  3. 2. Assessment of optimal suspension systems with regards to ride under different road profiles

    Master-uppsats, KTH/Fordonsdynamik

    Nyckelord :Ride comfort; Handling; Road profiles; ADAMS; Shaping filter method; Sinusoidal approximation method; Coherence; ISO 8608; Acceleration PSD s; Genetic Algorithm optimisation; ISO 2631.; åkkomfort; Kurvkörningsegenskaper; Vägprofiler; ADAMS; Formningsfiltermetod; Sinusformad approximationsmetod; Koherens; ISO 8608; Acceleration PSDs; Genetisk algoritmoptimering.;

    Sammanfattning : Passenger ride vibration comfort is a critical aspect to consider while developing any vehicle and there is a need to understand how the occupants would be affected when driving on different road profile roughness. Hence, road profile generation is critical as road profiles are used as inputs to simulation tools to investigate vehicle dynamic behaviour in depth. LÄS MER

  4. 3. Development of a Tool for Inverse Aerodynamic Design and Optimisation of Turbomachinery Aerofoils

    Master-uppsats, KTH/Flygdynamik

    Författare :Berkin Kurtulus; [2021]
    Nyckelord :Aerodynamics; Turbomachinery Airfoil design; Inverse Design Automation; Airfoil Optimization;

    Sammanfattning : The automation of airfoil design process is an ongoing effort within the field of turbo-machinery design, with significant focus on developing new reliable and consistent methods that can meet the needs of the engineers. A wide variety of approaches has been in use for inverse airfoil design process which benefit from theoretical inverse design, statistical methods, empirical discoveries and many other ways to solve the design problem.

  5. 4. Parameter Optimisation of EPAS Using CAE

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Shounak Bhattacharyya; Suraj Sivaramakrishnan; [2019]
    Nyckelord :Electronic Power Assist Steering; Optimization; Subjective Assessment; Objective Metrics;

    Sammanfattning : To keep up with technological as well as logistical challenges of the modern automobile market, major car manufacturing firms have resorted to virtual simulation tools. This enables the development as well as validation of vehicular models much before resources are invested into a new physical prototype. LÄS MER

  7. 5. Modelling Diversity of Solutions

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Linnea Ingmar; [2019]
    Nyckelord :;

    Sammanfattning : For many combinatorial problems, finding a single solution is not enough. This is clearly the case for multi-objective optimisation problems, as they have no single “best solution” and, thus, it is useful to find a representation of the non-dominated solutions (the Pareto frontier).
