11. Congested railways : influence of infrastructure and timetable properties on delay propagation
Sammanfattning : In this thesis the symptoms and underlying behaviour of congestion on railways are analysed and discussed. As well as in many other countries, Sweden faces increasing demand for transport. To meet this new demand, railways play an important role. LÄS MER
12. Optimisation models for train timetabling and marshalling yard planning
Sammanfattning : Railways provide high capacity, safe and energy efficient transportation of goods and passengers. However, railway transportation also suffers from intrinsic restrictions and the effectiveness and efficiency of the transportation depend on the railway actors’ ability to solve a set of hard and interconnected planning problems.

13. Computer-based decision support for handling uncertainty in railway traffic and transportation
Sammanfattning : Railway transportation has great potential, but interdependencies in the railway traffic make trains very sensitive to disturbances, which can bedifficult to handle. Using railway in an intermodal transport chain may complicate the interconnections with other modes if there is large uncertainty in the performance of the railway. LÄS MER
14. Simulation Studies for Improved Efficiency in Road and Rail Freight Transports
Sammanfattning : The demand for road and rail freight transport continues to grow with the expanding economy, while the climate crisis requires reduction in greenhouse gas emissions. Therefore, tools and solutions for reducing fossil fuel use and enabling more efficient use of infrastructure are needed. LÄS MER
15. Application of Predictive Analytics for Shunting Yard Delays
Sammanfattning : Increasing the modal share of rail freight transport is one of the main ways to achieve carbon neutrality in Europe. The perceived low reliability and predictability of rail freight services is one of the main challenges to overcome in reaching this target. LÄS MER
