  1. 1. An ILP-model for the Train platforming problem

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

    Författare :Simon Calderon; [2023]
    Nyckelord :Optimization; Integer programming; Train platforming; Train scheduling; Optimering; Heltalsprogrammering; Tåg; Järnväg; Schemaläggning;

    Sammanfattning : The goal of this thesis is to create an optimization model to optimize the routing of trains within railway stations. This problem is known as the train platforming problem, and the model we present is an integer programming model. By this model we aim to optimize factors such as walking distance, switch usage or platform usage. LÄS MER

    Sammanfattning : This study investigates methods for assessing threats in space. Space services are crucial to both civilian and military capabilities, and a loss of such systems could have severe consequences. Space systems are exposed to various types of threats. LÄS MER

  4. 3. Aerodynamic Optimization of Low Observable Engine Intake Duct

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Laszlo Vimlati; [2022]
    Nyckelord :NSGA-II; CFD; Air Intake; S-Duct; Optimization; Pressure Recovery; Distortion.; NSGA-II; CFD; Intagskanal; Optimering; Tryckåtervinst; Flödesdistorsion.;

    Sammanfattning : An aerodynamic shape optimization procedure was performed on a low observable engineintake duct. The intake duct was fixed in its throat and aerodynamic interface plane (AIP)sections, while leaving up to 7 design parameters free to deformation in the centroid curveand mid section profile.

  5. 4. Models for solid waste and its management in Stockholm metropolitan area

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Lars Arvidsson; Kasper Nordenram; [2022]
    Nyckelord :;

    Sammanfattning : In the transition from a linear economy to a sustainable circular economy, waste management is critical. This thesis approaches the management of Municipal Solid Waste (MSW) from the perspective of a mathematical modelling. Within the scope of the thesis, three mathematical models were developed.

  7. 5. Optimal control of articulated vehicles for tyre wear minimisation

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Vallan Maroof; [2021]
    Nyckelord :Articulated Vehicles; Optimal Control; Tyre Wear Minimisation; Sensitivity Analysis; Motion Planning; Lastbil; Ruttplanering; Däckslitage Minimering; Känslighetsanalys; Optimal Styrning;

    Sammanfattning : Tyre wear is a significant problem on today's road vehicles, particularly for heavy trucks. As the tyre wears, microplastics is released in the air causing long term health issues and environmental pollution. With the introduction of automated vehicles there is a big potential to improve tyre wear of heavy trucks. LÄS MER
