Prover and RATP strengthen collaboration

Following the joint presentation of a paper at the RSSRail 2023 conference, RATP and Prover have deepened their collaboration to perfect and industrialize the Integral Formal Proof (PFI) methodology. With the recent commissioning of the CBTC update on line 4 of the Paris metro, this approach has led to significant progress in system-level analysis, thereby enhancing passenger safety.  

Prover’s expertise in formal methods, particularly through the use of the HLL (High Level Language) and its dedicated tools, combined with the constant commitment of the teams, has led to significant advancements. Our team has thus contributed to the thorough assessment of the tracking function of this CBTC, together with experts from Sig4 Engineering. As a tool provider, expertise provider, and long-time partner of RATP, Prover stands out for its leading position in the field of critical systems analysis, thus ensuring reliable and efficient solutions for transport infrastructures.
