Automated early estimation of bridge interventions, possession windows and costs
Bridge managers need to generate a complete overview of required interventions, possession windows and the likely costs 10-20 years ahead of execution. These, even if approximate, help ensure stable train schedules. With the increasing amount of available data and the increasing desire to exploit digitalisation to improve decision-making…
