  1. 1. Coordinated Routing : applications in location and inventory management

    Författare :Henrik Andersson; Peter Värbrand; Marielle Christiansen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimization; coordinated routing; inventory routing; ship routing; location; decision support; mathematical modeling; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : Almost everywhere, routing plays an important role in everyday life. This thesis consists of three parts, each studying different applications where routing decisions are coordinated with other decisions. A common denominator in all applications is that an intelligent utilization of a fleet of vehicles is crucial for the performance of the system. LÄS MER

  3. 2. Applications of Resource Optimization in Wireless Networks

    Författare :Patrik Björklund; Peter Värbrand; Mikael Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; telecommunication; scheduling; gsm; wcdma; ad-hoc; frequency planning; Telecommunication; Telekommunikation;

    Sammanfattning : The demand for wireless communications is increasing every year, but the available resources are not increasing at the same rate. It is very important that the radio resources are used in an efficient way allowing the networks to support as many users as possible. LÄS MER

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

    Författare :Carl Henrik Häll; Jan Lundgren; Peter Värbrand; Karin Brundell-Freij; Linköpings universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Optimization modelling and methods for freight transportation in scheduled railways

    Författare :Kennet Melin; Peter Värbrand; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the planning process of a freight railway transportation company, a number of optimization problems arise. In this thesis, we study two of them; empty freight car distribution and line planning. LÄS MER

  7. 5. Airport Logistics : Modeling and Optimizing the Turn-Around Process
