    Abstract : The scope of this thesis is modelling and solving large-scale planning problems in the supply chain within the forest industry. Five research papers are included, the first three of which focus on the modelling, and the last two on the solution methods. READ MORE

  4. 19. A Framework for Evaluation and Design of an Integrated Public Transport System

    Author : Carl Henrik Häll; Jan Lundgren; Peter Värbrand; Karin Brundell-Freij; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand responsive; public transport; public transportation; planning; optimization; simulation; Anropsstyrd trafik; kollektivtrafik; kollektivtrafikplanering; optimering; simulering; Other technology; Övriga teknikvetenskaper;

    Abstract : Operators of public transport always try to make their service as attractive as possible, to as many persons as possible and in a so cost effective way as possible. One way to make the service more attractive, especially to elderly and disabled, is to offer door-to-door transportation. READ MORE

  5. 20. Modeling and Simulation of Dial-a-Ride and Integrated Public Transport Services

    Author : Carl Henrik Häll; Jan T. Lundgren; Stefan Voss; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dial-a-ride; simulation; optimization; modeling; paratransit; public transport; Other technology; Övriga teknikvetenskaper;

    Abstract : Traditional public transport systems are most often insufficient to provide a good transport service to everyone. Especially, it is not always possible for elderly and disabled persons to use the regular system consisting of timetabled services operating along fixed routes. READ MORE
