Estimation and prediction of bridge component condition states based on condition data availability to support the digitalized estimation of future interventions
(2023)To estimate the future interventions required on a bridge portfolio, bridge managers need to have an overview of their current condition states of all bridge components and an understanding of how these condition states will evolve in the future. As the exact current condition states of all components on all assets do not exist, as inspections take time and are not done simultaneously on all components of all bridges, this information has ...Report -
An algorithm to improve the efficiency and effectiveness of determining multi-component intervention programmes for railway networks that result in the lowest disruptions to service: A case study of Zollikofen-Brügg railway network
(2024)To ensure the stability of the train schedules, it is crucial to determine the optimal component-level intervention programs, their associated required possession windows, and their execution costs. This is a key step in the later phases of the intervention planning process. Network, production, and capacity managers at SBB would, therefore, benefit from an efficient and automated method for determining optimal intervention programs for ...Report -
Using algorithms to provide track managers with consistent and complete early estimates of possible future maintenance interventions
(2024)In the intervention planning process of Swiss Federal Railways (SBB), it is beneficial to have an early estimate of the required non-routine track interventions, their type, and the expected duration of track possessions. This information is crucial for track managers to effectively plan and allocate resources. Therefore, it would be advantageous for them to have a comprehensive and consistent overview of all the required interventions ...Report -
Using algorithms to provide bridge managers with consistent and complete early estimates of possible future maintenance interventions
(2023)It is advantageous in the development of train schedules to know far in advance when interventions are required on bridges, as well as the types of intervention and the extent of track possession required. So that SBB bridge managers can provide this information, it would be advantageous for them to obtain a consistent and complete overview of the required interventions and associated track possessions for all their bridges up to 25 years ...Report -

The use of BIM in the railway intervention planning process to support the early estimation of future interventions
(2024)This report describes the digitalisation of the railway intervention planning process using predictive maintenance algorithms and Building Information Modeling (BIM). It is proposed that this would improve the effectiveness and efficiency of estimating future interventions. This entails an understanding of (1) the current intervention planning process at the SBB, including the stakeholders involved and their associated responsibilities, ...Report
