About Artelys

Joining Artelys means, above all, becoming part of a stimulating environment, made up of passionate experts and giving yourself the opportunity to take part in projects addressing various complex issues, notably addressing the major challenges of our time.

  • Toyota Motor Europe (TME) enlisted Artelys to enhance the process of planning activities for the following day. Artelys developed an operational calculation module deployed as a micro-service for planning management directly integrated into the application developed in-house by TME. The module plans activities for the next day while optimizing multiple metrics using Artelys Kalis, a constraint programming solver with a dedicated interface for scheduling problems. The speed of computation allows for real-time adjustments to the schedule within a day in case of unforeseen events. The solution implemented by Artelys can schedule thousands of tasks in less than a minute. This solution is utilized seven days a week and is currently being deployed across all TME workshops.

  • Major project led by RTE (the French TSO), the TERRE project  (Trans-European Replacement Reserves Exchange) aims at developing an IT platform for the market clearing of services exchanged between the European producers and transmission systems operators. Artelys, together with its partners, is responsible for providing the platform’s market clearing engine. The algorithm goes through the resolution of complex and large mathematical optimization problems, which take into account the offers of the various suppliers, balancing requests and fairness goals between the actors. Receiving and matching bids and demands every hour of the day, the robustness and performance of the optimization engine are very strongly constrained: results are to be provided within 3 minutes for a problem containing up to 500,000 offers – including complex offers.
