  2. 1. Constructive cooperative coevolution for optimising interacting production stations

    Author : Emile Glorieux; Bengt Lennartson; Fredrik Danielsson; Bo Svensson; Johan Ölvander; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing automation; metaheuristic optimasion algorithm; optimised production technology; algorithm design and analysis; interacting production stations; sheet metal press lines; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Engineering problems have characteristics such as a large number of variables, non-linear, computationally expensive, complex and black-box (i.e. unknown internal structure). These characteristics prompt difficulties for existing optimisation techniques. READ MORE

  4. 2. Succinic acid production using metabolically engineered Escherichia coli

    Author : Christian Andersson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. READ MORE

  5. 3. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds

    Author : Erik Åstrand; Gunnar Bolmsjö; Fredrik Sikström; Heikki Remes; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GMAW; Fatigue; Welding procedures; Fillet welds; Weld quality; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. READ MORE

  6. 4. Manufacturing management and decision support using simulation-based multi-objective optimisation

    Author : Leif Pehrsson; David Stockton; Ng Amos; Mats Jackson; Raouf Hamzaoui; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Management; Decision Support; simulation; Multi-objective; optimisation; Production systems; Teknik; Technology;

    Abstract : A majority of the established automotive manufacturers are under severe competitive pressure and their long term economic sustainability is threatened. In particular the transformation towards more CO2-efficient energy sources is a huge financial burden for an already investment capital intensive industry. READ MORE

  7. 5. Multi-Robot Motion Planning Optimisation for Handling Sheet Metal Parts

    Author : Emile Glorieux; Bengt Lennartson; Fredrik Danielsson; Bo Svensson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-robot systems; motion planning; modelling and simulation; optimisation; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Motion planning for robot operations is concerned with path planning and trajectory generation. In multi-robot systems, i.e. with multiple robots operating simultaneously in a shared workspace, the motion planning also needs to coordinate the robots' motions to avoid collisions between them.
