What is RAMS?

RAMS (Reliability, Availability, Maintainability, Safety) is a process to avoid failures already in the planning stage of projects. RAMS Management ensures that systems are defined, risk analyses are performed, hazards are identified and detailed reviews and safety cases are executed and reported. One specific goal is to provide hard evidence to achieve authorization for operations.

  • Evaluation of the soundness of a system: Reliability, Availability and Maintainability (RAM), also with an additional check if all safety requirements are fulfilled (RAMS).
  • Modeling of complex scenarios fosters a better understanding of context, causes and effects. Probabilistic methods are used to model uncertainty.
  • Evaluation of critical failure combinations (Minimal Cuts Sets) and description of optimization potential with comprehensive assessment and reporting.

Fault Tree Analysis (FTA) is the core of RAMS. The FTA depicts the functional system and quantifies all relevant factors to evaluate reliability, availability, maintainability and safety of the complete system. All components of a system will be evaluated systematically and analyzed according to their roles and functions within the system.

  • Provides a visual summary of all plausible accident scenarios related to a certain hazard.
  • Identifies control measures and displays what a company is doing to control these scenarios.


RAMS works in compliance with relevant standards and guidelines (ISO 31000, ISO 31010).
