Failure Data for a Reliability Distribution Analysis

The Failures section provides following information for each failure belonging to a Reliability Distribution Analysis:

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.

Field Caption	Data Type	Description	Behavior and Usage
Asset ID	Character	The ID of the piece of equipment that failed. This value is mapped from a query or dataset.	For manually entered data, you can select the first cell in the column and select the Asset ID belonging to the piece of equipment that you added in the Assets section or enter the ID in the cell.
Censored	Logical	A value that indicates whether or not the datapoint is excluded.	Select the check box to censor the data in the selected row.
Datasheet	Character	A link that displays the datasheet associated with the failure event.	This column appears only when a query is the data source for the analysis.
Downtime	Numeric	The amount of corrective maintenance time for the piece of equipment after the failure occurs.	This value is mapped from a query or dataset or manually entered when you create the analysis.
Failure Date	Date	The date on which the failure of the piece of equipment occurred.	This value is mapped from a query or dataset or manually entered when you create the analysis and is required.
Ignore	Logical	Specifies whether the data in the associated row is excluded or included from analysis calculations.	When selected, excludes the data in the associated row from the analysis calculations and plots. When cleared, includes the data in the associated row in the analysis calculations.
Number of Failures	Numeric	The number of failed elements at each failure event.	This column appears only when the failure type is Failures Without Replacements. This value is mapped from a query or dataset or manually entered when you create the analysis.
Remarks	Character	Additional comments about the failure.	You can enter a value in this column manually.
Replaced	Boolean	A value that indicates whether replacements were made following each equipment failure. A replacement causes the entire piece of equipment to be renewed, thus resetting calculation of the time to failure.	This column appears only when the failure type is Failures Without Replacements. This value is mapped from a logical field in a query or dataset or manually entered when you create the analysis.
TTF	Numeric	The Time to Failure is the duration of time from when the piece of equipment is placed into service until it fails.	TTF may be expressed in terms of days, hours, cycles, units processed, etc. TTF values are calculated by the GE Digital APM system based on the failure dates and are shown in gray to indicate that they are read-only.
