A Comparison of Models for Rolling Stock Scheduling
Boris Grimm, Rowan Hoogervorst, Ralf Borndörfer
A major step in the planning process of passenger railway operators is the assignment of rolling stock, i.e., train units, to the trips of the timetable. A wide variety of mathemat…
Convergence Properties of Newton's Method for Globally Optimal Free Flight Trajectory Optimization
Ralf Borndörfer, Fabian Danecker, Martin Weiser
The algorithmic efficiency of Newton-based methods for Free Flight Trajectory Optimization is heavily influenced by the size of the domain of convergence. We provide numerical evid…
Newton's Method for Global Free Flight Trajectory Optimization
Ralf Borndörfer, Fabian Danecker, Martin Weiser
Globally optimal free flight trajectory optimization can be achieved with a combination of discrete and continuous optimization. A key requirement is that Newton's method for conti…
