The RAMS analysis (Reliability, Availability, Maintainability and Safety) was held in keeping with the requirements defined in CELENEC EN 50126-1, IEC 61511-1 and, in the case of railway applications, following the guidelines expressed in CELENEC CLC / TR 50126 -3.
 
The first turning point of the analysis is to determine the system that you are designing:
  • Reliability in terms of:
    • all possible system failure modes,  in the application and in the specified environment;
    • the probability of occurrence of any fault, or alternatively, the rate of occurrence of any failure;
    • the effect of the fault on the the system functionality.
  • Maintainability in terms of:
    • time for the execution of scheduled maintenance;
    • time to locate, identify and locate faults;
    • time to restore the failed system (unscheduled maintenance).
  • Operation and maintenance in terms of:
    • all possible operating modes and required maintenance, during the system life cycle;
    • all the aspects of the human factor.
  • Estimated availability of the system considering all the factors contained in the previous three points.

The second objective of the analysis is that, as regards the security of the system, to determine:

  • all possible dangerous situations in the system in all modes of operation, including maintenance, and in all environmental conditions;
  • the characteristic of every dangerous situation in terms of the seriousness of its consequences;
  • safety and safety-related failures;
  • maintainability of the system parts connected with security;
  • system operation and maintenance of the system parts connected with security;

usually the points listed above, are later it developed within the Risk Analysis.

 
Finally, the third objective of this analysis is to define a set of requirements, called RAMS requirements; these requirements are documented in a appropriate specification, so when it becomes part of the input information for the definition of system requirements.
