    Sammanfattning : The Exploitation of land for economic growth has been an ongoing issue for locals’ rights to land, especially indigenous people. In Sweden, EU’s largest producer of Iron ore, the conflict between the State, indigenous Sámi, and mining industries have caused many controversies over the years, where mining projects repeatedly infringe upon land inhabited by Sámi.

  5. 4. Production optimization using Discrete Event Simulation : Case study of Volvo Penta engine production line

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Antonio José Ramos Calderón; [2022]
    Nyckelord :DES; optimization; genetic algorithms; knowledge extraction; FACTS; MIMER;

    Sammanfattning : Simulation allows decision-makers in modern industries analyse the outputs of specific systems, and predict future ones based on certain decision variables when in combination with optimization and Lean. This project studies the production line of boat engines in Volvo Penta at Vara (Sweden), carrying out different experiments based on a verified and validated model of the real production system using FACTS Analyzer in order to improve the key performance indicators whilst comparing the optimization performance of four genetic algorithms (NSGA-II, NSGA-III, PSO and DE) and extracting knowledge using data mining.

  7. 5. Current Business Models in Lithium Exploration

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Martha Henderson; [2022]
    Nyckelord :lithium; mineral exploration; business models; mining; innovation; content analysis;

    Sammanfattning : The world is facing the challenge of transforming from fossil fuel dependant to a zero-emission econ-omy. This results in multi-fold mineral requirements for technologies such as wind turbines, solar pan-els, and electric vehicles; an exorbitant amount that cannot be fulfilled by recycling alone. LÄS MER
