Failure Modes and Reliability Analysis

Simulation Results in an FMRA

Analytical Results in an FMRA

The analytical results in the FMRA may include reliability or probability of failure (which are available in both XFMEA/RCM++/RBI and BlockSim), and criticality (which is available only in XFMEA/RCM++/RBI).

To perform analytical calculations, choose FMRA > Calculations > Calculate (Reliability).

In XFMEA/RCM++/RBI, if there are multiple systems (top-level items) or if the FMRA is synchronized with BlockSim, you will be prompted to specify a) which systems to calculate and/or b) whether to consider a more complex reliability-wise configuration that may have been modeled in the BlockSim diagrams. (See Calculation Options Window.)

In BlockSim, these calculations are available when you are using analytical FMRA diagrams. If there is only one system in the FMRA, this will calculate results for the entire FMRA. If there are multiple systems, you will be asked to choose whether you want to calculate the entire system hierarchy or just the currently selected system and its dependents.

Reliability and Probability of Failure

You can display the following FMRA columns in both XFMEA/RCM++/RBI and BlockSim:

Criticality Analysis

In XFMEA/RCM++/RBI only, you can also display the following FMRA columns for quantitative criticality analysis:
