21. On Determination of Inventory Cost Parameters
Sammanfattning : Efficient inventory control depends on correct values of inventory cost parameters, such as holding costs, shortage/stockout costs and ordering/setup costs. However, there exists surprisingly little research concerning the size of these parameters or how they should be determined. This thesis is devoted to increasing our knowledge of these matters.

22. Modeling Lateral Transshipments and Perishable Items in Inventory Systems
Sammanfattning : This thesis deals with two main areas in the field of stochastic inventory theory; ateral transshipments and perishable items. In the first part of this thesis we give an introduction to the field of inventory theory, and discuss some previous literature connected to the research presented in this thesis. LÄS MER
23. Fuel-Efficient Heavy-Duty Vehicle Platooning
Sammanfattning : The freight transport industry faces big challenges as the demand for transport and fuel prices are steadily increasing, whereas the environmental impact needs to be significantly reduced. Heavy-duty vehicle (HDV) platooning is a promising technology for a sustainable transportation system. LÄS MER
24. Applying Data Analytics to Freight Train Delays in Shunting Yards
Sammanfattning : The European Commission has foreseen a modal share of 30% by 2030 for rail freight transport. To achieve this increase in the modal share, enhanced reliability of rail freight services is required. Optimal functioning of shunting yards is one of the areas that can improve this reliability.

25. 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
