LEO in productive use

We have been working together with ÖBB for several years to optimise rail transport planning and make it more robust. LEO (LokEinsatzOptimierung - locomotive deployment optimisation) supports planners in their day-to-day work by optimising the timetable planning of a reference week with regard to various criteria and can be simulated in the overall system using our software tool.

The ''End of the Pandemic'' from a Modeling Perspective

Thus, the termination of modeling does not mean how we assess the situation, but results from a data limitation and is not our decision, but the consequence of political decisions. However, we are very much considering the consequences in the sense of the feedback described above, in order to possibly warn.
