Changing the Failure Rate Multiplier

The Failure Rate Multiplier defines the units for failure rate values. By default, Relyence Reliability Prediction sets the Failure Rate Multiplier to Failures per Million Hour, or FPMH. Typically, MIL-HDBK-217, 217Plus, and China's GJB/z 299 use FPMH as its base units, and Telcordia uses FITs (Failures in Time, or Failure per Billion Hours).

If you prefer to use different units for your failure rates, you can set your preferred units. Click Settings from the Account Management dropdown menu in the upper right corner of the Relyence Header Bar.

The Setting dialog appears.

In the Failure rate units field, select from Failures/Hour, Failures/Hundred Hours, Failures/Thousand Hours, Failures per Ten Thousand Hours, Failures per Hundred Thousand Hours, Failures/Million Hours (FPMH), or Failures/Billion Hours (FITs), or calendar-based units of Failures/Day, Failures/Month, Failures/Quarter, Failures/Year.

Note that this setting applies to all failure rate values in all Relyence Products. For example, when entering failure rate values in other Relyence Products, such as Relyence RBD and Relyence Fault Tree, the same Failure Rate Multiplier is in use.
