Delayed maintenance modelling considering speed restriction for a railway section (2017)
Journal Article
Shang, H., Berenguer, C., & Andrews, J. (in press). Delayed maintenance modelling considering speed restriction for a railway section. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 231(4), https://doi.org/10.1177/1748006X17709200

The deterioration of track geometry depends on several factors of which the speed of the train is one. Imposing a speed restriction can slow down the track deterioration and allows a longer survival time before a serious condition is achieved. Preven...

This work presents an efficient computational framework for prognostics by combining the particle filter-based prognostics principles with the technique of Subset Simulation, first developed in S.K. Au and J.L. Beck [Probabilistic Engrg. Mech., 16 (2... Read More about A new algorithm for prognostics using subset simulation.

A sensor selection method for fault diagnostics (2017)
Book Chapter
Reeves, J., Remenyte-Prescott, R., & Andrews, J. (2017). A sensor selection method for fault diagnostics. In Safety and Reliability – Theory and Application: ESREL 2017. CRC Press

In the modern world, systems are becoming increasingly complex, consisting of large numbers of components and their failures. In order to monitor system performance and to detect faults and diagnose failures, sensors can be used. However, using senso... Read More about A sensor selection method for fault diagnostics.

A modelling approach for railway overhead line equipment asset management (2017)
Journal Article
Kilsby, P., Remenyte-Prescott, R., & Andrews, J. (2017). A modelling approach for railway overhead line equipment asset management. Reliability Engineering and System Safety, 168, 326-337. https://doi.org/10.1016/j.ress.2017.02.012

© 2017 Elsevier Ltd The Overhead Line Equipment (OLE) is a critical sub-system of the 25 kV AC overhead railway electrification system. If OLE asset management strategies can be evaluated using a whole lifecycle cost analysis that considers degradati...

System design and maintenance modelling for safety in extended life operation (2017)
Journal Article
Andrews, J., & Fecarotti, C. (in press). System design and maintenance modelling for safety in extended life operation. Reliability Engineering and System Safety, 163, https://doi.org/10.1016/j.ress.2017.01.024

It is frequently the most cost effective option to operate systems and infrastructure over an extended life period rather than enter a new build programme. The condition and performance of existing systems operated beyond their originally intended de... Read More about System design and maintenance modelling for safety in extended life operation.
