Using reliability analysis to support decision making in phased mission systems (2017)
Journal Article
Zhang, Y., & Prescott, D. (2017). Using reliability analysis to support decision making in phased mission systems. Quality and Reliability Engineering International, 33(8), 2105-2119. https://doi.org/10.1002/qre.2170

Due to the environments in which they will operate, future autonomous systems must be capable of reconfiguring quickly and safely following faults or environmental changes. Past research has shown how, by considering autonomous systems to perform pha... Read More about Using reliability analysis to support decision making in phased mission systems.

A hierarchical coloured Petri net model of fleet maintenance with cannibalisation (2017)
Journal Article
Sheng, J., & Prescott, D. (2017). A hierarchical coloured Petri net model of fleet maintenance with cannibalisation. Reliability Engineering and System Safety, 168, https://doi.org/10.1016/j.ress.2017.05.043

Cannibalisation refers to a maintenance action where an unserviceable part in an inoperative platform is replaced by a serviceable part of the same type from another platform. It helps a fleet meet operational requirements when spares are in short su... Read More about A hierarchical coloured Petri net model of fleet maintenance with cannibalisation.

An information theoretic approach for knowledge representation using Petri nets (2016)
Presentation / Conference Contribution
Chiachío, M., Chiachío, J., Prescott, D., & Andrews, J. An information theoretic approach for knowledge representation using Petri nets. Presented at Future Technologies Conference 2016

A new hybrid approach for Petri nets (PNs) is proposed in this paper by combining the PNs principles with the foundations of information theory for knowledge representation. The resulting PNs have been named Plausible Petri nets (PPNs) mainly because... Read More about An information theoretic approach for knowledge representation using Petri nets.

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.

Modelling the effects of asset management decisions on a railway track section (2014)
Presentation / Conference Contribution
Prescott, D., & Andrews, J. D. Modelling the effects of asset management decisions on a railway track section. Presented at 2nd International Conference on Railway Technology: Research, Development and Maintenance

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.

A reliability analysis method using binary decision diagrams in phased mission planning (2009)
Journal Article
Prescott, D., Remenyte-Prescott, R., Reed, S., Andrews, J., & Downes, C. (2009). A reliability analysis method using binary decision diagrams in phased mission planning. Proceedings of the Institution of Mechanical Engineers, Part O: Journal of Risk and Reliability, 223(2), https://doi.org/10.1243/1748006XJRR202

The use of autonomous systems is becoming increasingly common in many fields. A significant example of this is the ambition to deploy UAVs (unmanned aerial vehicles) for both civil and military applications. In order for autonomous systems such as th...

Identifying the factors influencing track degradation on the UK rail network
Presentation / Conference Contribution
Clarke, S., & Prescott, D. Identifying the factors influencing track degradation on the UK rail network. Presented at Stephenson Conference : Research for Railways

As trains traverse track, the smoothness of its vertical geometry decreases. This degradation is linked to many interrelated factors, making it difficult to identify the primary causes. Through the use of multiple layer analysis, each factor was indi... Read More about Identifying the factors influencing track degradation on the UK rail network.
