FMRA Record Properties

The Properties tab of the Analysis panel allows you to view and modify the properties of any record that is currently selected in the FMRA hierarchy.

Note: The fields that are enabled in the interface and the options available in configurable drop-down lists will depend on the interface style settings that have been defined for the current project. You can choose Project > Management > Configurable Settings > Interface Style to open the Edit Interface Style (This Project) window and change the settings for the current project.

For every type of record, the properties under the Reliability Policy heading are used to set the reliability policy of that record. See Setting Reliability Policies.
For system items, the remaining properties are the same as those accessible from the system hierarchy. See Item Properties.
For FMEA records that can be viewed in the FMRA (i.e., functions, failures and causes), the remaining properties are the same as those that can be edited from an FMEA, with the addition of the following fields for failure records that are used for quantitative criticality analysis.
- Mode Ratio is the probability that the item failure will be due to the failure mode under consideration. In other words, this represents the percentage of all failures for the item that will be due to the given mode. This will be calculated automatically by the software based on all of the failure probabilities that have been defined for the analysis.
- Prob of Loss is a factor from 0 to 1 that describes the probability that this failure mode would result in a system failure. By default, this is set to 1 (Actual Loss). To enter a different value, double-click inside the field to display the Model Wizard.

Note: You cannot change the properties of any record used in an FMEA that is locked for editing by a change log. Records that are locked for this reason will be indicated by a locked FMEA icon in the User Access column of the FMRA.
