  1. 1. Structure exploiting optimization methods for model predictive control

    Författare :Emil Klintberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Multi-stage robust MPC; Optimization methods.; Model Predictive Control; Distributed optimization;

    Sammanfattning : This thesis considers optimization methods for Model Predictive Control (MPC). MPC is the preferred control technique in a growing set of applications due to its flexibility and to the natural way in which constraints can be incorporated in the control policy. LÄS MER

  3. 2. Dissipative formation of galaxies in hierarchical cosmology

    Författare :John Hultman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; merical methods; hydrodynamics; galaxies: formation; galaxies: elliptical; galaxies: structure; star formation; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Theoretical Astrophysics; teoretisk astrofysik;

    Sammanfattning : A description and detailed tests of a numerical code for simulations of galaxy formation is presented. The dynamics is followed with fully adaptive and Lagrangian Smooth Particle Hydrodynamics (SPH) combined with a gravitational tree method. The severe numerical problem of sub-resolution clustering is solved by merging of gas particles. LÄS MER

  4. 3. Supply Chain Inventory Control-Methods for Coordination and Evaluation

    Författare :Johan Marklund; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supply Chain; Inventory; Multi-Echelon; Stochastic; Decentralization; Centralized Control; Distribution; Divergent; Batch Ordering.;

    Sammanfattning : Thanks to the fierce competition and the globalization of markets as well as compa¬nies, supply chain management has emerged as one of the most urgent manage¬rial issues in business today. This thesis is devoted to one aspect of this vast problem area - the coordinated management/control of supply chain inventories. LÄS MER
