1. On the Optimization of Schedules of a Multitask Production Cell
Sammanfattning : Volvo Aero has invested in a complex production cell containing a set of multipurpose machines. The problem of finding optimal schedules for this multitask cell is a complex combinatorial optimization problem which is recognized as a flexible job shop problem. This thesis proposes an approach to find such schedules using mathematical optimization. LÄS MER
2. Mathematical Optimization in Flexible Job Shop Scheduling: Modelling, Analysis, and Case Studies
Sammanfattning : The major theme of this thesis is the mathematical optimization modelling of the flexible job shop scheduling problem. This problem is present in the so-called multitask cell—a production cell at GKN Aerospace's facility located in Trollhättan, Sweden—which has served as a case study during the work with this thesis.

3. Assessment of Robustness in Railway Traffic Timetables
Sammanfattning : A tendency seen for the last decades in many European railway networks is a growing demand for capacity. An increased number of operating trains has led to a delay sensitive system where it is hard to recover from delays, where even relatively small delays are easily propagating to other traffic.
