  1. 1. Efficient Optimization of Complex Products : A Simulation and Surrogate Model Based Approach

    Author : Johan Persson; Johan Ölvander; Petter Krus; Hirpa G. Lemu; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : This thesis investigates how to use optimization efficiently when complex products are developed. Modelling and simulation are necessary to enable optimization of products, but here it is assumed that verified and validated models of the products and their subsystems are available for the optimization.

  2. 2. Design and Optimization under Uncertainties : A Simulation and Surrogate Model Based Approach

    Author : Johan Persson; Johan Ölvander; David Aspenberg; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis deals with development of complex products via modeling and simulation, and especially the use of surrogate models to decrease the computational efforts when probabilistic optimizations are performed. Many methods that can be used to perform probabilistic optimizations exist and this thesis strives to present and demonstrate the capabilities of a few of them. READ MORE

  3. 3. On Knowledge Creation and Learning at the Intersection of Product Development and Engineering Education

    Author : Peter Hallberg; Johan Ölvander; Jonas Detterfelt; Kerstin Johansen; Johan Malmqvist; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Today’s demands on higher engineering education given the rapid transformation of society are, to say the least, multifaceted. Rapidly increased complexity of technology as well as adaptation to sustainability requirements are causing major transformations and mergers of whole domains of technology that strongly impact current and future engineering workforces within these domains, in particular, the need for new competencies.

  4. 4. Towards Design Automation for Additive Manufacturing : A Multidisciplinary Optimization approach

    Author : Anton Wiberg; Johan Andersson (Ölvander); Johan Persson; Lars Pejryd; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. READ MORE

  5. 5. Geometry Based Design Automation : Applied to Aircraft Modelling and Optimization

    Author : Kristian Amadori; Petter Krus; Johan Ölvander; Christopher Jouannet; Bento Silva de Mattos; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Abstract : Product development processes are continuously challenged by demands for increased efficiency. As engineering products become more and more complex, efficient tools and methods for integrated and automated design are needed throughout the development process. READ MORE
