  1. 11. Maintenance analysis and modelling for enhanced railway infrastructure capacity

    Författare :Stephen Mayowa Famurewa; Peter Veit; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : Railway transportation is a sustainable mode of transportation for reasons of safety, cost, carbon emission and energy requirements. It has a notable role in economic expansion in terms of passenger and freight services. LÄS MER

  3. 12. Towards concurrent planning of railway maintenance and train services

    Författare :Tomas Lidén; Jan Lundgren; Martin Joborn; Ann-Brith Strömberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Efficiency in the public and freight transportation systems is of crucial importance for a society. Railways can offer high capacity and relatively low environmental impact, but require that several technical systems are tuned and operate well. LÄS MER

  4. 13. Concurrent planning of railway maintenance windows and train services

    Författare :Tomas Lidén; Jan Lundgren; Martin Joborn; Dennis Huisman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Efficiency in public and freight transportation systems is of great importance for a society. Railways can other high capacity and relatively low environmental impact, but require that several technical systems are tuned and operate well. Specifically there is a tight interdependency between infrastructure and trains. LÄS MER

  5. 14. Topics in convex and mixed binary linear optimization

    Författare :Emil Gustavsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; subgradient methods; Lagrangian dual; recovery of primal solutions; inconsistent convex programs; ergodic sequences; convex optimization; mixed binary linear optimization; maintenance scheduling; preventive maintenance; deterioration cost; inconsistent convex programs;

    Sammanfattning : This thesis concerns theory, algorithms, and applications for two problem classes within the realm of mathematical optimization; convex optimization and mixed binary linear optimization. To the thesis is appended five papers containing its main contributions. LÄS MER

  7. 15. On Distributed Control-by-Wire Systems for Critical Applications

    Författare :Roger Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-triggered communication; fault-tolerance; distributed systems; dependable systems; inherent redundancy; control-by-wire;

    Sammanfattning : The implementation of closed loop control systems is an important field for the exploitation of embedded real-time computer systems. One can find a particularly interesting class of closed loop control applications within vehicle dynamics control. LÄS MER
