ABSTRACT
There is significant experience in the field of systems reliability analysis. Here the Fault Tree Analysis technique has played an important role due to its power for emphasizing some aspects that exert an enormous influence on the reliability of redundant systems, specifically those designed to operate with high availability and safety requirements. The Failure Modes and Effect Analysis technique is recognized as a powerful analysis tool because it combines the structuring and the completeness of the method with descriptive capacities that improve its integrity, giving the analyst the flexibility to describe in a more complete way all the characteristics of the system from either the design or the operation standpoints. The Component Reliability Model Approach is the preferred method to use when the failure rates are known or can be estimated, as well as the average repair times, and other parameters of the components-failure modes, which depend on statistical data.
