UniSA researchers test the TPOD system.

Traditionally train plans are created by drawing train paths one at
a time on a train graph, either manually or assisted by computer
software. This task often takes many weeks to create a feasible
train plan. Even once the train plan is complete, changes in demand
and network operating conditions as the day of operation
approaches, necessitate changes to the train plan. As such, train
planners spend much of their time trying to maintain a feasible
timetable, rather than an optimum timetable.
This project builds on Project 20, which developed train scheduling
software that can quickly produce good train plans on demand - TPOD
(Train Plans on Demand). With the software, train planners can
specify a train departure and arrival time, and train plans and
graphs will be automatically generated for review. On the day of
operation, when necessary, the system can be used to revise the
network operating plan to recover – in an optimal way –
from disruptions to the planned schedule.
The new project 156 continues the development of TPOD and aims to
assure industry of its value by undertaking case studies on lines
operated by Rail CRC participants.
The project was independently evaluated by STEM Partnerships in
2006, and the technology was estimated to have the potential to
deliver a risk-free-value of $36.8 million over 15 years to the
rail industry. Taking into account the risks associated with
delivering the technology, the project is expected to return a
value of $31.9 million.
Progress to date:
- Different optimisation models were evaluated and as a consequence
the TPOD model is the focus of work.
- TMG International is marketing ScheduleMiser, a commercial version
of TPOD. Commercialisation arrangements are still to be
finalised.
Future Outcomes:
- Industry case studies undertaken with specific solution methods for
industry participants.
- Documented methodology and software developed for the industry
participants.
- Commercialisation of the software through a technology transfer
agreement (licensing) between Rail CRC and TMG.
