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.
