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... Read More about A Petri net approach to fault verification in phased mission systems using the standard deviation technique.

A network traffic flow model for motorway and urban highways (2013)
Journal Article

The research reported in this paper develops a network level traffic flow model (NTFM) which is applicable for both motorway and urban roads. It forecasts the traffic flow rates, queue propagation at the junctions and travel delays through the networ... Read More about A network traffic flow model for motorway and urban highways.

Fault propagation modelling for fluid system health monitoring (2011)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2011). Fault propagation modelling for fluid system health monitoring. International Journal of Performability Engineering, 7(11),

Fault diagnostics systems are incorporated to determine the health of the system they monitor. There are however times when the diagnostics system reports faults which do not exist. This situation commonly arises at system start-up when high vibrat... Read More about Fault propagation modelling for fluid system health monitoring.

An efficient phased mission reliability analysis for autonomous vehicles (2010)
Journal Article
Remenyte-Prescott, R., Andrews, J., & Chung, P. (2010). An efficient phased mission reliability analysis for autonomous vehicles. Reliability Engineering and System Safety, 95(3), https://doi.org/10.1016/j.ress.2009.10.002

Autonomous systems are becoming more commonly used, especially in hazardous situations. Such systems are expected to make their own decisions about future actions when some capabilities degrade due to failures of their subsystems. Such decisions are...

An efficient real-time method of analysis for non-coherent fault trees (2009)
Journal Article
Remenyte-Prescott, R., & Andrews, J. (2009). An efficient real-time method of analysis for non-coherent fault trees. Quality and Reliability Engineering International, 25(2), https://doi.org/10.1002/qre.955

Fault tree analysis is commonly used to assess the reliability of potentially hazardous industrial systems. The type of logic is usually restricted to AND and OR gates which makes the fault tree structure coherent. In non-coherent structures not only...

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...

Analysis of non-coherent fault trees using ternary decision diagrams (2008)
Journal Article

Risk and safety assessments performed on potentially hazardous industrial systems commonly utilise Fault Tree Analysis (FTA) to forecast the probability of system failure. The type of logic for the top event is usually limited to AND and OR gates whi... Read More about Analysis of non-coherent fault trees using ternary decision diagrams.

An enhanced component connection method for conversion of fault trees to binary decision diagrams (2008)
Journal Article

Fault Tree Analysis (FTA) is widely applied to assess the failure probability of industrial systems. Many computer packages are available which are based on conventional Kinetic Tree Theory methods. When dealing with large (possibly non-coherent) fau... Read More about An enhanced component connection method for conversion of fault trees to binary decision diagrams.

Prime implicants for modularised non-coherent fault trees using binary decision diagrams (2007)
Journal Article

This paper presents an extended strategy for the analysis of complex fault trees. The method utilises simplification rules, which are applied to the fault tree to reduce it to a series of smaller subtrees, whose solution is equivalent to the original...

Fault tree analysis is commonly used in the reliability assessment of industrial systems. When complex systems are studied conventional methods can become computationally intensive and require the use of approximations. This leads to inaccuracies in...

Kilsby, P., Remenyte-Prescott, R., & Andrews, J. D. (in press). Modelling asset management of railway overhead line equipment.

The overhead line equipment (OLE) is a critical sub-system of the 25kV AC overhead railway electrification system. There is a need to evaluate OLE asset management strategies through a whole life cost analysis that considers degradation processes and...
