  1. 1. Development of an investment model for pumped storage hydropower

    Magister-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Pontus Gustavsson; Eric Swanmark; [2023]
    Nyckelord :pumped storage hydropower; investment models; energy storage; grid balancing;

    Sammanfattning : The energy market is evolving, with a prediction of heavily increased consumption and, consequently, increased production. In parallel, EU directives with targets prioritising fossil-free electricity production, reduction of greenhouse gas emissions and becoming climate neutral by 2050, poses a challenge for the current state of electricity production in the Nordics.

  3. 2. Beyond Disruptions: Optimizing Supply Chain Resilience : A qualitative and quantitative analysis of the aftermarket supply chain

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Sara Andersson; Jesper Karlsson; [2023]
    Nyckelord :Modelling Supply Chain Resilience; Supply Chain Disruptions; Semi-structured Interviews; Robustness Analysis; Flow Optimisation; Supply Chain Network Topology; Performance Measure;

    Sammanfattning : The world is changing, what has been known to work has been put to the test when both the geopolitical and the environmental climate are changing. War, a pandemic, material shortage, financial difficulties and an overall dis- tressed global transportation sector have shown that the ever-more important topic of resilience is crucial to stay relevant in today’s competitive markets.

  4. 3. Omkonstruktion av ljusanordning : Ett förbättringsarbete hos Zetterbergs

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Erik Dahlin; Alexander Jalandoni Sjöberg; [2023]
    Nyckelord :Bending; CAD; Customisation; Design For Manufacturing DFM ; Lorry; Manufacturing; Modu-larisation; Product development; Product family; Topology optimisation; Variants.; Bockning; CAD; Design For Manufacturing DFM ; Kundanpassning; Lastbil; Modularisering; Produktutveckling; Produktfamilj; Tillverkning; Topologioptimering; Varianter.;

    Sammanfattning : Kundanpassning är ett ökande problem för tillverkare och det gäller även för Zetterbergs därproblemet nu är att konstruera lastbilsprodukter som ska passa till alla kunder vars lastbils-fabrikat varierar. Syftet med studien var att utveckla CAD-modeller för en ljusanordning medbred kundanpassning, lågt komponentantal och mindre skador vid tillämpning. LÄS MER
