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

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

    Abstract : 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. READ MORE

  2. 2. Optimal Sequential Decisions in Hidden-State Models

    Author : Juozas Vaicenavicius; Erik Ekström; Huyên Pham; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; sequential analysis; optimal stopping; optimal liquidation; drift uncertainty; incomplete information; stochastic filtering;

    Abstract : This doctoral thesis consists of five research articles on the general topic of optimal decision making under uncertainty in a Bayesian framework. The papers are preceded by three introductory chapters.Papers I and II are dedicated to the problem of finding an optimal stopping strategy to liquidate an asset with unknown drift. READ MORE

  3. 3. Optimal Truck Scheduling : Mathematical Modeling and Solution by the Column Generation Principle

    Author : Myrna Palmgren; Torbjörn Larsson; Niklas Kohl; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

    Abstract : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. READ MORE

  4. 4. On Logistics in the Strategy of the Firm

    Author : Tobias Kihlén; Mats Abrahamsson; Andreas Norrman; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Business and economics; logistics; strategy; resource-based view; positioning theory; Ekonomi; Business and economics; Ekonomi;

    Abstract : The purpose of this thesis is to describe and analyse the role of logistics in the strategy of the firm. Leading to this purpose are empirical observations of firms that manage to grow under sustained profitability, by the means of logistics.The clothing retailers H&M and Inditex manage to pursue strategies of growth under sustained profitability.

  5. 5. Optimal Control of Electrified Powertrains

    Author : Martin Sivertsson; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Diesel-Electric; Hybrid Electric Vehicles;

    Abstract : Vehicle powertrain electrification, i.e. combining the internal combustion engine (ICE) with an electric motor (EM), is a potential way of meeting the increased demands for efficient and low emission transportation, at a price of increased powertrain complexity since more degrees of freedom (DoF) have been introduced.
