A general approach to assessing SHM reliability considering sensor failures based on information theory (2024)
Journal Article
Wu, W., Cantero-Chinchilla, S., Prescott, D., Remenyte-Prescott, R., & Chiachío, M. (2024). A general approach to assessing SHM reliability considering sensor failures based on information theory. Reliability Engineering and System Safety, 250, Article 110267. https://doi.org/10.1016/j.ress.2024.110267

Structural health monitoring systems (SHM) involve implementing damage identification strategies to determine the health state of structures. However, it is important to pay close attention to the system degradation, especially the...

Modular asset management framework based on Petri-net formalisations and risk-aware maintenance (2023)
Journal Article
Hadri, O., & Prescott, D. (2024). Modular asset management framework based on Petri-net formalisations and risk-aware maintenance. Reliability Engineering and System Safety, 243, Article 109828. https://doi.org/10.1016/j.ress.2023.109828

Probabilistic risk analysis (PRA) is fundamental in safety assessment. Current PRA tools face notable limitations for complex systems, such as the heavily reliance on historical failure data. Moreover, existing tools cannot replicate complex asset ma... Read More about Modular asset management framework based on Petri-net formalisations and risk-aware maintenance.

A novel fault detection and diagnostic Petri net methodology for dynamic systems (2023)
Journal Article
Badmus, T. A., Remenyte-Prescott, R., & Prescott, D. (2023). A novel fault detection and diagnostic Petri net methodology for dynamic systems. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, https://doi.org/10.1177/1748006x231212539

Faults can have significant, negative impacts on the operation and performance of simple and complex dynamic systems. Based on the integration of Bayesian network diagnostic features with Petri net formalism, the existing Bayesian-supported Petri net...

Using a Novel Hierarchical Coloured Petri Net to Model and Optimise Fleet Spare Inventory, Cannibalisation and Preventive Maintenance (2019)
Journal Article
Sheng, J., & Prescott, D. (2019). Using a Novel Hierarchical Coloured Petri Net to Model and Optimise Fleet Spare Inventory, Cannibalisation and Preventive Maintenance. Reliability Engineering and System Safety, 191, Article 106579. https://doi.org/10.1016/j.ress.2019.106579

Spare part availability is crucial to restoring inoperative platforms to the working state. Platforms failing during operation undergo corrective maintenance to replace failed components with spares. To reduce the frequency of this unplanned, correct...

A coloured Petri net framework for modelling aircraft fleet maintenance (2019)
Journal Article
Sheng, J., & Prescott, D. (2019). A coloured Petri net framework for modelling aircraft fleet maintenance. Reliability Engineering and System Safety, 189, 67-88. https://doi.org/10.1016/j.ress.2019.04.004

The aircraft fleet maintenance organisation is responsible for keeping aircraft in a safe, efficient operating condition. Through optimising the use of maintenance resources and the implementation of maintenance activities, fleet maintenance manageme...

Using coloured Petri nets to investigate fleet cannibalisation (2015)
Journal Article
Sheng, J., & Prescott, D. (2015). Using coloured Petri nets to investigate fleet cannibalisation. International Journal of Comadem, 18(2),

Cannibalisation is a maintenance activity that involves removing serviceable parts from inoperative platforms to replace unserviceable parts of the same type in other platforms. It can provide a significant benefit to fleet readiness, particularly if... Read More about Using coloured Petri nets to investigate fleet cannibalisation.

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.
