Failure Modes and Reliability Analysis (FMRA)

The Failure Modes and Reliability Analysis (FMRA) feature is available in both Xfmea/RCM++/RBI and BlockSim.

In Xfmea/RCM++/RBI, the FMRA displays all of the system hierarchy and FMEA records from the current project that could have an impact on system reliability/maintainability/criticality calculations (which may include items, functions, failures and causes). If you define the necessary properties for these records (reliability policy, operating time, etc.), you can use the FMRA to calculate or simulate a variety of results based on the assumption of a reliability-wise series configuration.

For more advanced analyses — including the ability to change the reliability-wise configuration — you can synchronize the FMRA you built in Xfmea/RCM++/RBI with reliability block diagrams in BlockSim.

• Enabling and viewing the FMRA

• Building the FMRA hierarchy

• Tips for setting FMRA record properties, including:

• • Setting the reliability policies

  • Using rating scales to set the reliability policy

  • Batch update reliability policies

  • Using mirror groups

  • Setting the operation properties

  • Allocating target reliability and availability

  • Highlights based on target reliability/availability

• FMRA diagrams and reliability-wise configurations

• Analytical calculation results

• Simulation results (only in RCM++/RBI or BlockSim)
