Samordnad, effektiv planering av järnvägsinfrastrukturunderhåll

Coordinated, efficient railway infrastructure maintenance planning

The project aims to develop an approach for planning the maintenance of railway infrastructure that makes maintenance operations more efficient and/or effective. More efficient maintenance activities are activities with equivalent resources improves the condition of the system more than existing approaches; or those that achieve equal improvement with less spent resources. Resources here refers to cost or time requirements. Planning should allow for coordinated maintenance actions where maintenance is performed in several places when a track section is shut down. The maintenance planning method combines modern, statistically based methods for assessing the railway condition with models describing costs and risks of different maintenance tasks. The approach includes optimizing of planned maintenance activities based partly on data-driven monitoring of the system's current status and deterioration rate, the estimates of cost and time requirements and risks of various maintenance operations, such as delays. Calculations of system condition and its deterioration rate also allow prognostics, which also will be integrated in the planning model. A more efficient and coordinated planning of maintenance primarily contributes to higher capacity of the railway system. The proposed project is a three-year collaboration Project between Luleå University of Technology, the Swedish Transport Administration and eMaintenance365.
