Fault tree analysis is commonly used in the reliability assessment of industrial systems. When complex systems are studied conventional methods can become computationally intensive and require the use of approximations. This leads to inaccuracies in...

Modelling asset management of railway overhead line equipment
Presentation / Conference Contribution
Kilsby, P., Remenyte-Prescott, R., & Andrews, J. D. (in press). Modelling asset management of railway overhead line equipment.

The overhead line equipment (OLE) is a critical sub-system of the 25kV AC overhead railway electrification system. There is a need to evaluate OLE asset management strategies through a whole life cost analysis that considers degradation processes and...
