1. Mathematical Optimization in Flexible Job Shop Scheduling: Modelling, Analysis, and Case Studies
Abstract : 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.

2. Conflict-Free Routing of Mobile Robots
Abstract : The recent advances in perception have enabled the development of more autonomous mobile robots in the sense that they can operate in a more dynamic environment where obstacles surrounding the robot emerge, disappear, and move. The increased perception of Autonomous Mobile Robots (AMRs) allows them to plan detailed on-line trajectories in order to avoid previously unforeseen obstacles, making AMRs useful in dynamic environments where humans, traditional fork-lifts, and also other mobile robots operate.

4. On scheduling using optimizing SMT-solvers
Abstract : Modern production systems are becoming more complex by the year and flexibility of production is one of the key factors to success. Companies want to be able to provide a customized product that fits exactly the customer requirements and, therefore production systems have to be able to produce a wide range of product variants.

5. An investigation of change over sensitive heuristics in an industrial job shop environment
Abstract : The research in this thesis has investigated scheduling and Changeover Sensitive Heuristics (CSHs). The overall aim was to investigate the relationship between scheduling and changeovers and to develop and examine new scheduling heuristics that are intelligent enough to optimise both due dates and changeover requirements.
