1. Operation and maintenance performance of rail infrastructure : Model and Methods
Sammanfattning : Congestion of roads and sky, increasing energy costs and a demand to reduce emissions, have created a need to shift transportation from road and air to rail. Consequently, rail utilisation is increasing, adding stress to the rail infrastructure and time constraints to maintenance. LÄS MER
2. Cooperative Transportation Planning and Cost Allocation
Sammanfattning : A freight forwarder may consolidate its goods transportations in order to achieve a more efficient operation. When goods transportations are consolidated, they may reduce operational costs, e.g. labor and fuel. LÄS MER
3. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation
Sammanfattning : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. LÄS MER
4. Automatic Model Generation and Scalable Verification for Autonomous Vehicles : Mission Planning and Collision Avoidance
Sammanfattning : Autonomous vehicles such as mobile driver-less construction equipment bear the promise of increased safety and industrial productivity by automating repetitive tasks and reducing manual labor costs. These systems are usually involved in safety- or mission-critical scenarios, therefore they require thorough analysis and verification. LÄS MER
5. On Incentives affecting Risk and Asset Management of Power Distribution
Sammanfattning : The introduction of performance based tariff regulations along with higher media and political pressure have increased the need for well-performed risk and asset management applied to electric power distribution systems (DS), which is an infrastructure considered as a natural monopoly. Compared to other technical systems, DS have special characteristics which are important to consider. LÄS MER
