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...

An asset management framework for wind turbine blades considering reliability of monitoring system (2023)
Presentation / Conference Contribution
Wu, W., Prescott, D., Remenyte-Prescott, R., Saleh, A., & Chiachio Ruano, M. (2023, September). An asset management framework for wind turbine blades considering reliability of monitoring system. Presented at 33rd European Safety and Reliability Conference (ESREL 2023), Southampton, UK

In this study, a wind turbine (WT) blade asset management (AM) Petri net (PN) model is presented, which incorporates risk-based maintenance and structural health monitoring (SHM). Firstly, PN modules cover the entirety of the blade AM process, descri... Read More about An asset management framework for wind turbine blades considering reliability of monitoring system.

Improving the Modelling Capability of an Integrated Fault Detection and Diagnostic Petri Net Methodology for Dynamic Systems (2023)
Presentation / Conference Contribution
Badmus, T. A., Prescott, D., & Remenyte-Prescott, R. (2023). Improving the Modelling Capability of an Integrated Fault Detection and Diagnostic Petri Net Methodology for Dynamic Systems.

The existing Generalised Stochastic Petri Net and modified Bayesian Stochastic Petri Net (GSPN-mBSPN) methodology has demonstrated improved modelling capabilities for fault diagnosis in dynamic systems with feedback control loops. However, the GSPN-m... Read More about Improving the Modelling Capability of an Integrated Fault Detection and Diagnostic Petri Net Methodology for Dynamic Systems.

Fault Tree to Petri Net Conversion for the Analysis of a Standby System (2023)
Presentation / Conference Contribution
Prescott, D. (2023, April). Fault Tree to Petri Net Conversion for the Analysis of a Standby System. Presented at 62nd ESReDA Seminar, University of Twente, the Netherlands

Although fault trees are widely used, their quantitative analysis is limited by the need for basic event independence. Dynamic and Dependent Tree Theory (D2T 2 ) has been proposed to overcome this limitation and requires dependent system fault tree e...
