Purpose and goal

The project intends to develop an approach for planning the maintenance of railway infrastructure that makes maintenance operations more efficient or effective. More efficient maintenance activities are activities with equivalent resources improves the condition of the railway facility more than existing approaches; or those that achieve equal improvement with less spent resources. Resources here refers to the cost or time requirements. Planning should allow for coordinated maintenance actions where maintenance is performed in many places when a track section is shut down.

Expected results and effects

A more efficient and coordinated planning of maintenance primarily contributes to higher capacity of the railway system.

Planned approach and implementation

The maintenance planning method combines modern, statistically based methods for assessing the railway condition assessment with models describing costs and risks of different tasks. The approach includes optimizing planned maintenance based partly on monitoring of the plant´s current status and how quickly it deteriorates, the estimates of cost and time requirements and risks of various maintenance operations. Calculations of plant condition and the condition deterioration rate also allows prognostics, which also will be incorporated into the planning model.
