RAMS Software – Get the best Reliability, Availability & Maintainability Analysis 

RAMS (Reliability, Availability, Maintainability and Safety) analyses are essential components of critical systems design and management. Neglecting RAMS during design can result in expensive failures, redesigns, and safety events. Furthermore, RAMS analyses are required by standards and regulations in industries such as rail, aerospace, medical, defense and nuclear.


Typical RAMS tasks include:

  • Identify and mitigate risk due to equipment failure modes
  • Design of Safety Related Systems (SRS)
  • Redundancy / Fault Tolerance: how many standby units to hold, and operation profile (warm or cold)
  • Design of efficient Built In Test (BIT) plan for high coverage and failure isolation
  • Design system to be easily and quickly maintained
  • Achieve high system availability

Systems Risk analysis



Reliability is defined as the probability that an item will perform a defined function without failure under stated conditions, for a stated period of time.


Availability is basically defined as:


MTBF = Mean Time Between Failures
MTTR = Mean Time To Repair (or Replace)

Many variants of availability definitions exist depending on maintenance, inspections and logistic time.
