1. Evaluating and Improving the Transport Efficiency of Logistics Operations
Sammanfattning : The thesis focuses on evaluating and improving the transport efficiency of two types of logistics operations in the supply chain.One research area is the production of raw material in construction operations, specifically earthmoving operations. LÄS MER
2. Novel Algorithms for Optimal Transport via Splitting Methods
Sammanfattning : This thesis studies how the Douglas–Rachford splitting technique can be leveraged for scalable computational optimal transport (OT). By carefully splitting the problem, we derive an algorithm with several advantages. LÄS MER
3. On optimal mission planning for conventional and electric heavy duty vehicles
Sammanfattning : Ever-growing energy consumption and CO2 emissions due to the increase in road transport are major challenges that attract international attention, especially policy makers, logistic service providers and customers considering environmental, ecological and economic issues. Other negative side-effects caused by the growth of the road transport are the extensive economic and social costs because of traffic congestion. LÄS MER
4. Simulation Studies of Impact of Heavy-Duty Vehicle Platoons on Road Traffic and Fuel Consumption
Sammanfattning : The demand for road freight transport continues to grow with the growing economy, resulting in increased fossil fuel consumption and emissions. At the same time, the fossil fuel use needs to decrease substantially to counteract the ongoing global warming. LÄS MER
5. 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
