undeniable successes
For more than 10 years, the SNCF and Artelys cooperate closely in order to optimize the railway sector. Artelys has been involved during projects dealing with traffic regulation and supervision, pricing optimization, resources optimization and industrialization of optimization engines.
SNCF : An innovative partnership
For more than 10 years, Artelys has been providing its expertise in terms of mathematical optimization, mathematical programing and operations research to the SNCF. Optimization algorithms have been developed thanks to this partnership and the solutions are fully integrated to the industrial tools of decision support of the SNCF.
In co-operation with SNCF Innovation & Research, Artelys actively participates to research by producing proofs of concept, prototypes, high-level scientific contents, advise towards optimization methods, statistics and data, expertise on the feasibility and scaling of prototypes or the exploitation of research.
- Industrialize and integrate software prototypes produced by the R&D,
- Maintain and develop solutions in production (cloud hosting, automated deployments, software quality control, paper monitoring),
- Provide technical support and incident resolution of the applications in production,
- Realize quantitative research based on these software solutions,
- Assist ROAD concerning architectural choices and software tools.
Since 2012, Artelys assists ROAD in these missions, for which it has become the exclusive provider since 2014, by:
- Providing skills related to business application, SNCF software requirements, in applied mathematics, statistics and computer science,
- Adjusting the effort delivered to the projects’ needs (12 part-time engineers who provide from 3 to 8 ETP by month, the effort is jointly planned one month in advance and adjusted every week according to the needs).
From the perspective of mathematical optimization, Artelys has been able to deal with many SNCF issues such as interventions planning, maintenance planning, operators planning or resources allocation.
The implemented algorithms construct optimal solutions while respecting operational, legal and security constraints.
- Olistic: discrete events simulator of railway systems. Inputs are a set of operating trains. This simulator models network constraints (for example minimal distance between the trains), exploitation constraints (precedence order between the trains), and incidents (immobilization of a train, determinist or stochastic delays). The simulation enables the users to understand how the delays are propagated over the network through the constraints, and spacing conflicts.
- Plaisance: scheduling of operators’ duty days which enables to size human resources, the analysis of exploitation scenarios and a pre-operational planning of the human resources allocation over the transportation plan. Plaisance produces schedules where trains are affected to operators (Driving Agents – AdC and Trains Commercial Service Agents – ASCT) and which respect the constraints in terms of duty-day validity and which is consistent with the geographic distribution of the operators.
- PANAM: planning and programming of maintenance tasks for SNCF rolling equipment over multisite tactical and pre-operational horizons. The schedule attempt to minimize the costs related to the maintenance and to reduce the risks of equipment immobilization.
Artelys also ensures the integration of these optimization modules to software solutions or to cross-platform decision support tools (smartphone, web browsers, OS).
