1. Modeling and Simulation of Dial-a-Ride and Integrated Public Transport Services
Sammanfattning : Traditional public transport systems are most often insufficient to provide a good transport service to everyone. Especially, it is not always possible for elderly and disabled persons to use the regular system consisting of timetabled services operating along fixed routes. LÄS MER
2. Discrete Event Simulation of Bus Terminals
Sammanfattning : Public transport is important to society as it provides spatial accessibility and reduces congestion and pollution in comparison to other motorized modes. To assure a high-quality service, all parts of the system need to be well-functioning and properly planned. One important aspect for the system's bus terminals is their capacity. LÄS MER
3. An Operations Research Approach for Daily Emergency Management
Sammanfattning : Emergency services play a vital role in society by providing help to affected people and minimizing damage to public and private assets as well as the environment during emergencies. However, these organizations deal with problems of increasing demand uncertainty and resource shortage over time. LÄS MER
4. Towards optimal railway track utilization based on societal benefit
Sammanfattning : Infrastructure managers in railway systems are striving to have as efficient track utilization as possible. There are no unanimous interpretation of efficiency in terms of track utilization, but the aim of the Swedish Transport Administration is to allocate track capacity such that societal benefit is maximized.
