  2. 1. Foliated Transportation Networks - Evaluating feasibility and potential

    Author : Joakim Kalantari; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid transportation systems; transportation network modeling; intelligent transportation systems.; transportation planning and control; transportation network simulation; transportation network optimization; Transportation networks; transportation network performance; mixed model transportation; transportation network efficiency;

    Abstract : Neither the critical role that transportation plays for economic activities nor its negative external effects can be denied. At the same time, the resources required to sustain and develop the transportation system to an adequate degree and at the required pace are limited. READ MORE

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

    Author : Myrna Palmgren; Torbjörn Larsson; Niklas Kohl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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

  5. 3. Energy Optimal Operation of Electric Trains : Development of a Driver Advisory System

    Author : Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Evert Andersson; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The electric traction system used in trains is the most energy efficient traction system in the transportation sector. Moreover, it has the least NOx and CO2 emissions in comparison to other transportation systems (e.g. busses, passenger cars, airplanes, etc. READ MORE

  6. 4. Ghosts of the Past or Facilitators of the Future? : Firm-System Interactions in the Transition to Electrified Goods Transportation

    Author : Viktor Werner; Thomas Magnusson; Ksenia Onufrey; Solmaz Filiz Karabag; Peter Wells; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : If you visit Linköping, you have good chances to see electrified cars, or you may even take a ride on an electric city bus. However, you will have some difficulty spotting one of the very few electric trucks operating in the city. READ MORE

  7. 5. Dynamic Optimization of Transportation Networks with Delays

    Author : Martin Heyden; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The topic of this thesis is the optimal control of transportation networks. The problem studied is a dynamical extension of a classical problem in economics, in which the objective is to distribute goods to maximize welfare, whilst satisfying constraints on production and consumption.
