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...

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.
