Quantifying the impact of variability in railway bridge asset management (2018)
Conference Proceeding
Yianni, P. C., Neves, L. C., Rama, D., Andrews, J. D., Tedstone, N., & Dean, R. (2018). Quantifying the impact of variability in railway bridge asset management.

Bridge asset management is often a challenging and complicated task due to the diversity, multitude and variation of bridge configurations. Much research has been carried out in the field of asset management which has resulted in a wealth of models t...

Producing effective maintenance strategies to control railway risk (2018)
Conference Proceeding
Fecarotti, C., & Andrews, J. (2018). Producing effective maintenance strategies to control railway risk. In Probabilistic Safety Assessment and Management PSAM 14 , September 2018 , Los Angeles, CA

This paper describes the main features of a modelling framework that sets out a systematic approach to railway infrastructure asset management enabling decisions to be made based not only on costs but on service performance and safety. First, the fra... Read More about Producing effective maintenance strategies to control railway risk.

Modelling adaptive systems using plausible Petri nets (2018)
Conference Proceeding
Chiachío, J., Chiachío, M., Prescott, D., & Andrews, J. (2018). Modelling adaptive systems using plausible Petri nets. In 8th International Workshop on Reliable Engineering Computing, “ Computing with Confidence ”

One of the main challenges when analyzing and modelling complex systems using Petri nets is to deal with uncertain information, and moreover, to be able to use such uncertainty to dynamically adapt the modelled system to uncertain (changing) contextu...

Using Petri-Net modelling for a data-driven approach to bridge management and safety (2018)
Conference Proceeding
Yianni, P. C., Neves, L. C., Rama, D., Andrews, J., & Dean, R. (2018). Using Petri-Net modelling for a data-driven approach to bridge management and safety.

Bridge portfolio managers have a difficult task managing a large, varied portfolio of aging assets in a squeezed financial climate and on networks with increasing usage. Therefore, decision support tools are becoming more and more integral in managin... Read More about Using Petri-Net modelling for a data-driven approach to bridge management and safety.

A Bayesian assessment for railway track geometry degradation prognostics (2018)
Conference Proceeding
Chiachío, J., Chiachío, M., Prescott, D., & Andrews, J. (2018). A Bayesian assessment for railway track geometry degradation prognostics. In Proceedings of the 4th European Conference of the Prognostics and Health Management Society

Advanced PHM techniques have the potential to substantially reduce railway track maintenance costs while increasing safety and availability. However, there is still a significant lack of knowledge and experience in relation to suitable PHM models and...

A mathematical programming approach to railway network asset management (2018)
Conference Proceeding
Fecarotti, C., & Andrews, J. (2018). A mathematical programming approach to railway network asset management.

A main challenge in railway asset management is selecting the maintenance strategies to apply to each asset on the network in order to effectively manage the railway infrastructure given that some performance and safety targets have to be met under b...

Vulnerability assessment modelling for railway networks (2018)
Conference Proceeding
Meesit, R., & Andrews, J. (2018). Vulnerability assessment modelling for railway networks. In Proceedings of the 10th IMA International Conference on Modelling in Industrial Maintenance and Reliability. https://doi.org/10.19124/ima.2018.001.16

Railway networks are prone to many different potential disruptive events such as technical failures (e.g. the failure of aging components), natural disasters (e.g. flooding) and intentional man-made disasters (e.g. trespass and suicide). Assessing th... Read More about Vulnerability assessment modelling for railway networks.
