6. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables
Sammanfattning : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. LÄS MER
7. Improving Timetable Robustness and Punctuality of Railway Traffic : A Combined Simulation-Optimization Approach for Nonperiodic Timetabling on Double-Track Lines
Sammanfattning : To evaluate the robustness of a timetable against minor delays, it can be simulated. A natural question following a simulation is how the results can be used to improve the timetable, which has received limited attention in the literature. LÄS MER
8. Challenges with Driverless and Unattended Train Operations
Sammanfattning : Demand for transportation continues to increase, for both freight and passenger services. One of the most energy-efficient modes of transportation is rail. One solution to increase the attractiveness of rail transport is to introduce automatic train operation (ATO) with a high grade of automation (GoA). LÄS MER
9. 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
10. Simulation-based Evaluation of Fixed to Flexible Transit
Sammanfattning : Emerging technologies have inspired a wide array of flexible public transit system designs characterized by varying degrees of demand-responsive routing and scheduling. The availability and synthesis of new data sources with higher degrees of spatial and temporal richness brought on by advancements in Intelligent Transport Systems allow for monitoring and responding to evolving supply-demand imbalances in real-time.
