About GRIF software

GRIF (GRaphical Interface for reliability Forecasting) is a software suite of excellence that determines the fundamental indicators of reliability and dependability - RAMS (Reliability, Availability, Maintainability and Safety).

GRIF comprises 3 packages and 12 modules allowing the user to choose the most appropriate modeling technique for the resolution of the studied system (block diagrams, fault trees, Markov graphs, Petri nets...).

The software integrates mature and powerful calculation engines (ALBIZIA and MOCA-RP), as well as pre-integrated architectures that facilitate the modeling of any reliability study.


GRIF Software has over 40 years of expertise in modeling reliability studies

The result of more than 40 years of Research and Development within TotalEnergies, GRIF, the RAMS analysis software suite, has mature, high-performance calculation engines with modeling capabilities that meet the requirements of all your reliability studies, whatever your field of activity.
