  2. 1. Railway traffic disturbance management

    Author : Johanna Törnquist; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Railway traffic; Transportation; Re-scheduling; Disturbance management; Decision support systems;

    Abstract : With the increasing traffic volumes in many railway networks and reports on capacity deficiencies that result in insufficient punctuality and reliability, the need for efficient disturbance management solutions becomes evident. This thesis focuses on solutions that aim to minimise the consequences of disturbances for the various stakeholders and specifically on methods for re-scheduling the traffic. READ MORE

  4. 2. A System-of-Systems Approach for Enhancing Asset Management of Railway System

    Author : Jaya Kumari; Ramin Karim; Adithya Thaduri; Pierre Dersin; Miguel Castaño Arranz; Mirka Kans; Luleå tekniska universitet; []

    Abstract : In Sweden, railway transport of freight and passengers is a significant portion of the total transport system. The demand for railway transport is forecasted to increase in the coming decades. One of the main reasons for this ever-increasing demand is the requirement for sustainable transport, nationally and globally. READ MORE

  5. 3. Exploring Public Procurement of Swedish Railway Infrastructure Maintenance

    Author : Jens Aldenlöv; Bjarne Bergquist; Tina Karrbom Gustavsson; Per Erik Eriksson; Henrik Eriksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Procurement; Railway Maintenance; Supply Chain Management; Contract Design; Kvalitetsteknik; Quality Technology Management;

    Abstract : In 2002, Sweden started to outsource its railway infrastructure maintenance. Through gradual exposure (i.e. outsourcing one contract area at a time), the Swedish Transport Administration has developed its competence of being a client towards its contractors. READ MORE

  6. 4. Railway Infrastructure Robustness : Attributes, evaluation, assurance and improvement

    Author : Per Norrbin; Ragnar Hedström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : According to the European program Horizon 2020, multifaceted challenges in transportinfrastructure include 1) making infrastructure more resilient to keep pace with the increasing mobility needs; 2) reducing the impact of infrastructure on the environment;and 3) dealing with declining resources to maintain and upgrade transport infrastructure. New design and maintenance approaches must be developed to handle these issues, ascurrent methods are inadequate. READ MORE

  7. 5. Structural Control and Identification of Civil Engineering Structures

    Author : Tarek Edrees; Francesc Pozo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Abstract : In general, the main purpose of a structural control system is to apply powerful control techniques that improve the behaviour of civil structures under various kinds of dynamic loading. The first part of this thesis presents novel applications of posicast and input shaping control schemes that have never previously been applied in the field of structural control. READ MORE
