To use a Weibull data set to calculate the failure rate for a part, you create a data link to this data set. The Prediction Data pane for a part linked to a Weibull data set displays a Linked to Weibull message and display-only failure data for this linked data set. For Time, you enter the time at which to calculate the part’s failure rate. The default value is the mission time specified in the Project’s Mission Profile file. For more information, see Linking Weibull Data to a Part.
