This paper presents the development of a simulation model for airline cockpit crew rostering. The developed simulation model supports airlines in performing comparative analyses of different crew rostering scenarios. The model was developed in collaboration with a major European airline, leveraging actual historical pairing, crew and roster data to accurately model the airline crew rostering process. The simulation model is based on a novel solution method that is based on the Hungarian assignment algorithm and that exploits the resemblance of the weekly crew rostering problem to a minimum-cost bipartite matching problem. An assessment of the performance of the simulation model has shown that the simulation model is able to construct rosters of near-optimal solution quality in limited computational time. To test the applicability of the developed model as a scenario analysis tool, two experiments have been performed. The insights the performed experiments have provided confirm the practical value of the developed simulation model.

This report presents the Final design of the Design Synthesis Exercise (DSE) to 'Capture a Small Asteroid and Change its Orbit' at the Faculty of Aerospace Engineering at Delft University of Technology. The bachelor programme 'Aerospace Engineering' comprises several projects enabling students to explore aeronautics and space from different kinds of perspectives. The Design Synthesis Exercise serves as the conclusion to this programme. During this final project students integrate their previously obtained knowledge and skill to examine a specific design problem in groups of ten students for the duration of eleven weeks. This final report is the last in a series of four and documents the detailed design of the concept that was chosen in the mid-term report.
