Adding a Formula to a Failure Mode

You can add an existing formula to a failure mode, to assign a failure computation. The Reliability Source widget helps create and structure reliability sources and formulas, and to associate them with failure modes.

  1. From the Edit section of the action bar, click Open Reliability Source .
  2. In the Reliability Source widget, click the reliability source containing a formula.
  3. Drag the formula onto a failure mode, in the architecture tree.
    • In the architecture tree, the formula is associated to the failure mode.

      Note: To associate another formula to a failure mode, you need first to dissociate the current formula. Right-click the formula in the architecture tree and select Dissociate.
    • In the work area, if the failure mode is associated with an undeveloped event, which is not a gate nor a transfer, the event turns to a basic event.
