An information theoretic approach for knowledge representation using Petri nets (2016)
Conference Proceeding
Chiachío, M., Chiachío, J., Prescott, D., & Andrews, J. (2016). An information theoretic approach for knowledge representation using Petri nets.

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.

Railway bridge asset management using a Petri-Net modelling approach (2016)
Conference Proceeding
Yianni, P. C., Rama, D., Neves, L. C., & Andrews, J. D. (2016). Railway bridge asset management using a Petri-Net modelling approach.

Infrastructure assets can be difficult to manage due to the array of defects, the variety of environmental situations and the different operational scenarios. A number of studies have tried to model bridge asset management. The main focus of these mo... Read More about Railway bridge asset management using a Petri-Net modelling approach.

Performance modelling of fuel cell systems through Petri nets (2016)
Conference Proceeding
Fecarotti, C., & Andrews, J. (in press). Performance modelling of fuel cell systems through Petri nets.

This paper introduces a model based on the Petri net method for the performance evaluation of fuel cell systems during operation. The model simulates the operation of the fuel cell stack and its supporting systems by taking into account the causal re...

Modelling railway bridge degradation based on historical maintenance data (2016)
Journal Article
Le, B., & Andrews, J. (in press). Modelling railway bridge degradation based on historical maintenance data. Safety and Reliability, 35(2), https://doi.org/10.1080/09617353.2015.11691040

As structures deteriorate with age and use, it is necessary to devise a maintenance plan to control their states in a cost effective way. In order to evaluate the effectiveness of alternative maintenance strategies their success must be measured by t...
