A model for calculating volumes of trains as flows given demand and capacity restriction
Martin Aronsson, Tomas Lidén
This report presents a novel approach to calculate volumes of trains from a set of requirements describing the transportation demands. The model presented is based on a multi commo…

Disaggregation in Bundle Methods: Application to the Train Timetabling Problem
Abderrahman Ait Ali, Per Olov Lindberg, Jan-Eric Nilsson +2
Bundle methods are often used to solve dual problems that arise from Lagrangian relaxations of large scale optimization problems. An example of such problems is the train timetabli…
