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

A Petri net model for railway bridge maintenance (2017)
Journal Article
Le, B., Andrews, J., & Fecarotti, C. (2017). A Petri net model for railway bridge maintenance. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 231(3), doi:10.1177/1748006X17701667. ISSN 1748-006X

This article describes the application of the Petri net modelling approach to managing the maintenance process of railway bridges. The Petri net model accounts for the degradation, inspection and repair processes of individual bridge elements in inve... Read More

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, doi:10.1016/j.ress.2017.01.024. ISSN 0951-8320

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

A Petri net approach for performance modelling of polymer electrolyte membrane fuel cell systems (2016)
Journal Article
Fecarotti, C., Andrews, J., & Chen, R. (in press). A Petri net approach for performance modelling of polymer electrolyte membrane fuel cell systems. International Journal of Hydrogen Energy, doi:10.1016/j.ijhydene.2016.05.138. ISSN 0360-3199

Fuel cells are promising technologies for zero-emission energy conversion and power generation. However, durability and reliability are among the main barriers to their commercialisation. Clearly the system performance depends on the reliability of t... Read More

Toward more realistic viscosity measurements of tyre rubber–bitumen blends
Journal Article
Lo Presti, D., Fecarotti, C., Clare, A. T., & Airey, G. (2014). Toward more realistic viscosity measurements of tyre rubber–bitumen blends. Construction and Building Materials, doi:10.1016/j.conbuildmat.2014.03.038. ISSN 0950-0618

The measurement of rheological properties of the tyre rubber bitumen blends is often challenging due to presence of suspended tyre rubber’s crumbs. Furthermore, the phase separation during the course of measurements makes the viscosity of these non-h... Read More
