The thesis is written in English and is available from the author upon request. This work deals with Railway Optimization, and in particular it focuses on the Train Timetabling Problem (in the basic version on a corridor and in the extension to a railway network), and on the Train Unit Assignment Problem. Integer Linear Programming (ILP) formulations are proposed for both problems, and their continuous and Lagrangian relaxations are used to obtain optimal and heuristic solutions to real-world instances.
