This project aimed to develop a model which assessed track
components and deterioration rates across a large and spatially
dispersed rail network. While various researchers have developed
degradation models for various types of track components, there had
been no model which addressed the interactions between different
components and their deterioration rates.
The project objectives were to produce workable track maintenance
scheduling tools that included: a) decision model frameworks to
allow implications of resourcing decisions to be modelled b)
situation specific rules on the essential elements of an
appropriate decision making and management structure for track
repair resource deployment c) a framework for resource scheduling
of major track maintenance repair infrastructure and their
associated repair teams and d) decision support models for
allocation of resources across and between regions.
This project is now complete, and while it became significantly
larger and more complex as the project progressed, there have been
good outcomes with the logical design of the model for rail
replacement completed. The project has been discontinued.
Results:
- Literature review of existing track maintenance scheduling and
degradation models completed
- Failure modes for ballasted track identified and reported on by
component and function
- Possessions and possession management at RIC characterised and
reported
- Costing method and unit rates developed for MPM civil track work
– report detailing cost equations completed
- Development of model for response of maintenance system to changes
in funding levels completed and report written detailing the model
- Development of model for scheduling of maintenance completed
