Abstract

Railway infrastructure managers now have to deal with the new operators’ requests for capacity. Planning the new construction or reconstruction of infrastructures must be carried out very carefully due to the huge investment needed. This paper studies a Constraint Programming (CP) model of the \“Railway Infrastructure Saturation Problem” (RISP). The model applies to assess the capacity of a junction or a station. Two resolution algorithms have been developed and combined to be applied to a real case study.
