TrainTRACS - Train Crew Diagramming Software
Tracsis’ market leading labour optimisation package, TrainTRACS, has a comprehensive parameter list to cater for all types of labour rules, and accounts for route and traction knowledge with multi-depot provision. Capping on driver and shift types per depot is part of the software, as are other specialised tools for maximum schedule efficiency and performance. As every company is different, there is a comprehensive cost weighting facility for promoting and discouraging bespoke features in a shift.
Interactive checking of shifts against a labour agreement completely eliminates 'illegal' shifts. There is also the ability to set average turn length per depot or groups of depot "links".
TrainTRACS - what can it do for you?
- Improve productivity for drivers and train crew as well as schedulers, rosterers and diagramming staff (2 – 10% efficiency savings are typical)
- Permit rapid creation of efficient and operable schedules
- Greatly increase schedule robustness
- Identify and eliminate illegal turns
- Provide the ability to carry out ‘what if’ contingency analysis in a short space of time
- Provide a method of fast production for quality short-term schedules (e.g. for engineering works)
- Provide an indispensable tool to assist in timetable change and franchise bidding
TrainTRACS - data requirements
Typical data requirements for TrainTRACS are:
- A complete set of rolling stock diagrams with coupling / uncoupling information added
- A current set of crew diagrams and rolling stock diagrams (if available) for calibration purposes
- Full list of terms and conditions – the diagramming compendium. This will include any working practices considered favourable / anti social etc. and any local agreements
- Any proposed changes to Terms & Conditions
- Any "unwritten rules"
TrainTRACS has pre-configured interfaces with other train planning software such as VoyagerPlan, TrainPlan and DISPO.
How it works - the TrainTRACS framework
The optimisation system has two stages:
Stage I: BUILD
Builds a large set of feasible candidates shifts according to a wide variety of parameters which represent the driver / train crew work rules; various time allowances; route and traction knowledge.
Stage II: SCHEDULE
Selects a subset from the candidate shifts to form the solution schedule. The technique used is based on the set covering model which is solved by Integer Linear Programming. Users can augment the model by adding side constraints for controlling the total number of shifts of some predefined types and/or depots. The objectives of minimising the total number of shifts, or minimising the total schedule cost, or a combination of them can be chosen by the user.
