Scheduling Infrastructure Renewal for Railway Networks [PDF]
Journal of Infrastructure Systems, 2019 The pressing necessity to renew infrastructure assets in developed railway systems leads to an increased number of activities to be scheduled annually. Scheduling of renewal activities for a railway network is a critical task because these activities often require a significant amount of time and create a capacity conflict in operation scheduling. This
