Generic Algorithms for Scheduling Problems with Changeover Costs

The topic of my master thesis were scheduling problems that involve changeover costs and that arise in several industrial applications such as mailroom insert planning, printed circuit board manufacturing and cutting tool management for CNC machines. In my thesis I implemented several algorithms to solve such problems, either optimally or approximately, and performed extensive experiments to evaluate the quality of these algorithms on large-scale real-world instances. The focus of this talk will be to show that two variants of the above scheduling problems can be solved by using algorithmic techniques that are well-known to computer-scientists, namely flow networks and the travelling salesman problem.
