Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
To ensure passenger safety and minimise unnecessary maintenance costs, it is vital for track engineers to accurately predict when railway assets require a renewal. This research aims to create a Petri net methodology that models the behaviour of an S&C ...
