  1. 1. Optimal thinning : a theoretical investigation on individual-tree level

    Författare :Peter Fransson; Åke Brännström; Ola Lindroos; Oskar Franklin; Per Lundberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest management; Simulation; Optimization; Spatially explicit model; Individual-based model;

    Sammanfattning : Paper I: In paper I, we asked how a tree should optimally allocate its resources to maximize its fitness. We let a subject tree grow in an environment shaded by nearby competing trees. The competitors were assumed to have reached maturity and had stopped growing, thus creating a static light environment for the subject tree to grow in. LÄS MER

  3. 2. Simulation-based multi-objective optimization of productivity and worker well-being

    Författare :Aitor Iriondo Pascual; Anna Syberfeldt; Dan Högberg; Erik Brolin; Johan Ölvander; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ergonomics; Productivity; Optimization; Simulation; User Centred Product Design; Användarcentrerad produktdesign; VF-KDO; VF-KDO;

    Sammanfattning : In industry, simulation software is used to simulate production, making it possible to predict events in production, calculate times and plan production, even in the early phases of the production development process. Software known as digital human modelling (DHM) tools can also be used to simulate humans working in production. LÄS MER

  4. 3. Advances in High Porductivity - High Quality Machining

    Författare :Marcel Escursell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; Quality; Machining; Productivity;

    Sammanfattning : Quality, productivity and flexibility are vital factors in todays machining industry in order to remain competitive. Nowadays, finished products not only have to be produced within specific tolerance limits, but they also have to posses high standards in terms of surface integrity, i.e. LÄS MER

  5. 4. On Optimization-Based Coordination of Automated Vehicles in Confined Sites

    Författare :Stefan Kojchev; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motion control; cooperative systems; optimal control; Automated vehicles; optimization.; multi-agent systems; graph theory; optimal scheduling;

    Sammanfattning : Autonomous driving is a major technological challenge, offering potential improvements in safety, efficiency, and comfort for daily transportation. However, the full-scale implementation of fully automated vehicles (AVs) remains distant, primarily due to safety concerns. LÄS MER

  7. 5. Roll pass design for improved flexibility and quality in wire rod rolling

    Författare :Conny Eriksson; Ulf Ståhlberg; Magnus Jarl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; wire rod; roll pass design; working range; productivity; swedish wire rod mills; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The thesis treats roll pass design in wire rod rolling of stainless steel for sequences and series built up by two-symmetrical grooves. It is focused on predicting rolling flexibility, also called working range, as well as product quality. For analysing the flexibility a computer program has been developed. LÄS MER
