Some mathematical programming-based models for a simplified evaluation of the capacity of railway networks

In this master's thesis, two similar models that have recently appeared in the literature aimed at establishing sets of constraints that incorporate basic variables of flow or number of circulations on elements of a railway network are analyzed and extended to the case of networks with a genera...

description In this master's thesis, two similar models that have recently appeared in the literature aimed at establishing sets of constraints that incorporate basic variables of flow or number of circulations on elements of a railway network are analyzed and extended to the case of networks with a general configuration.
