System-wide assessment of intervention strategies for railway infrastructure (2014)
Conference Proceeding
Rama, D., & Andrews, J. D. (2014). System-wide assessment of intervention strategies for railway infrastructure.

The existing railway infrastructure exhibits faster degradation rates and requires more maintenance effort as a result of increased utilisation. At the same time, due to increased numbers of freight and commuter trains obtaining access to the railway...

A stochastic model for railway track asset management (2014)
Journal Article
Andrews, J., Prescott, D., & De Rozières, F. (2014). A stochastic model for railway track asset management. Reliability Engineering and System Safety, 130, https://doi.org/10.1016/j.ress.2014.04.021

The determination of the strategy to ensure that the geometry for railway track is kept within acceptable limits, in a cost effective manner, is a complex process. It requires the simultaneous consideration of the activities which govern inspection,... Read More about A stochastic model for railway track asset management.

Modelling the effects of asset management decisions on a railway track section (2014)
Conference Proceeding
Prescott, D., & Andrews, J. D. (in press). Modelling the effects of asset management decisions on a railway track section. In Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance. https://doi.org/10.4203/ccp.104.166

This paper reports on the development of a Markov model that uses real-world deterioration, inspection and maintenance data to assess railway track asset management. The model allows both asset management personnel and track maintenance engineers to... Read More about Modelling the effects of asset management decisions on a railway track section.

Road network modelling for maintenance planning (2014)
Conference Proceeding
Yang, C., Remenyte-Prescott, R., & Andrews, J. (2014). Road network modelling for maintenance planning.

In this paper a novel road network flow model is presented, suitable for modelling both motor-way and urban roads. A road network is modelled using a directed graph, consisting of typical roads and junctions, with different traffic flow inputs throug...

A Petri net approach to fault verification in phased mission systems using the standard deviation technique (2014)
Journal Article
Lloyd, M. D., Andrews, J., Remenyte-Prescott, R., Pearson, J. T., & Hubbard, P. (2014). A Petri net approach to fault verification in phased mission systems using the standard deviation technique. Quality and Reliability Engineering International, 30(1), https://doi.org/10.1002/qre.1478

Health management systems are now standard aspects of complex systems. They monitor the behaviour of components and sub-systems and in the event of unexpected system behaviour diagnose faults that have occurred. Although this process should reduce...
