Measurement Data Records

<Measurement> Data record stores information about the Reliability Growth Analysis, which is a data format used to create a Reliability Growth Analysis. The following table provides an alphabetical list and description of the fields that exist for the Reliability Growth Analysis family, which appear when you manually enter data on the Reliability Growth Analysis window. The information in the table reflects the baseline state and behavior of these fields.

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.

Data for event-based analysis using failure dates

<Measurement Name>Tab

Field Caption	Data Type	Description	Behavior and Usage
Asset ID	Character	The ID of the Asset that failed.	This value is mapped from a query or dataset or manually entered when you create the analysis.
Cumulative Time <units>	Number	The Cumulative Time to Failure, which is the total runtime for a population of Assets at the moment that a failure occurs in one of them.	Values in this field are calculated by the GE Digital APM system and are read-only.
Date	Date	The date on which the failure occurred.	This value is mapped from a query or dataset or manually entered when you create the analysis and is required. If you delete a value in the Date field for an event-based analysis that is based on dates, when you select Finish, an error message will appear.
Downtime Units	Number	The amount of time that passed from the time the Asset failed until it was returned to service.	This information helps determine the total operating time of a piece of equipment or location. <Units> corresponds with the value selected in the Time Units list on the Provide Information for Downtime screen for the analysis.
Failures	Number	The number of failures represented by each datapoint. Cells in this column will contain the value 1 (one) by default, which indicates that the analysis data is not grouped, and one datapoint represents one failure. A value that is not equal to 1 (one) indicates that the analysis data is grouped, and each datapoint represents more than one failure or an amount of data.	This value can optionally be mapped from a query or dataset or manually entered when you create the analysis.
Ignore	Logical	A check box field that indicates whether or not the data on the selected row is ignored.	When selected, the data in the associated row will be excluded from the analysis. When cleared, data in the selected row will be included in the analysis. You can modify this value manually.
Remarks	Character	Comments about the failure.	You can enter a value in this field manually.
Segment	Logical	The segment to which the data belongs.	Values displayed in this field are read-only.
Time <units>	Number	The Time to Failure, which is the amount of time between the date the Asset was put into service until the date that it failed. If the data includes an installation date for the Asset , this value is calculated from the installation date. If the data does not include an installation date, this value is calculated from the first failure. <Units> corresponds to the value selected in the Operating Time Units list on the Time Unit field for the analysis.	This value is calculated automatically by the GE Digital APM system. If the value in this field is greater than the value in the GOF Statistic field, the Passed GOF field is set to True.

Assets Tab

Field Caption	Data Type	Description	Behavior and Usage
Asset ID	Character	The Record ID of the Asset that is being analyzed.	This value is mapped from a query or dataset or manually entered when you create the analysis.
Installation Date	Date	The date on which the Asset was installed.	This field appears only for analyses based on failure dates. This value is mapped from a query or dataset or manually entered when you create the analysis.
Last Replacement Date	Number	The last date or time at which the Asset failed.	Values in this column are calculated by the GE Digital APM system and are read-only. For data that contains cumulative operating time, this field is Last Replacement <Measurement>.

Data for event-based analysis using cumulative operating time

<Measurement Name> Tab

Field Caption	Data Type	Description	Behavior and Usage
Asset ID	Character	The ID of the Asset that failed.	This value is mapped from a query or dataset or manually entered when you create the analysis.
COT <units>	Number	The Cumulative Operating Time, which is the total amount of time that has passed since the Asset was placed into service.	<Units> corresponds with the value selected in the Time Units list on the Select Data Fields screen for the analysis. This field is sorted in ascending order by default. This value is mapped from a query or dataset or manually entered when you create the analysis, and is required. Note: For analyses based on cumulative operating time, if the values in the Failure Date column are not in the same order as the values in the COT (units) column (e.g., if the Failure Date 1/1/2012 has a COT of 1000 and the Failure date 1/2/2012 has a COT of 990), when you select OK, a message will appear, stating that sorting cumulative operating time values from smallest to largest will result in failure dates that are not in order from earliest to latest. As a result, no dates will be shown in the analysis results; only cumulative operating time will be shown.
Cumulative Time <units>	Number	The Cumulative Time to Failure, which is the total runtime for a population of Assets at the moment that a failure occurs in one of them.	Values in this field are calculated by the GE Digital APM system and are read-only. Note: The Cumulative Time is the total runtime for a piece of equipment or location after the analysis has started. This may be different from the COT, which is the total runtime of the piece of equipment or location since it was created. In our example, the haul truck has a mileage of 11,028 before the analysis starts, and fails at a mileage of 27,393. The COT is the total mileage on the truck, 27,293. The Cumulative Time is the mileage the truck has run since the analysis started (27,393-11,028=16,365). If the piece of equipment or location is brand new (i.e., the truck has a mileage of 0), the Cumulative Time and the COT will be the same.
Date	Date	The date on which the failure occurred.	This value is mapped from a query or dataset or manually entered when you create the analysis and is required. If you delete a value in the Date field for an event-based analysis that is based on dates, when you select Finish, an error message will appear. This value is optional, but in order for dates to be displayed throughout the analysis, ALL failures must have a failure date. If one or more failure dates are missing, then no dates will be shown in the analysis; only cumulative operating time will be shown. For instance, in Example 2, the data does not include dates on which the haul truck broke down, so the analysis results will be able to predict the next failure in cumulative operating times only (e.g., the next failure will occur at 324,001 miles).
Failures	Number	The number of failures represented by each datapoint. Cells in this column will contain the value 1 (one) by default, which indicates that the analysis data is not grouped, and one datapoint represents one failure. A value that is not equal to 1 (one) indicates that the analysis data is grouped, and each datapoint represents more than one failure or an amount of data.	This value can optionally be mapped from a query or dataset or manually entered when you create the analysis.
Ignore	Logical	A check box field that indicates whether or not the data on the selected row is ignored	When selected, the data in the associated row will be excluded from the analysis. When cleared, data in the selected row will be included in the analysis. You can modify this value manually.
Remarks	Character	Comments about the failure.	You can enter a value in this field manually.
Segment	Logical	The segment to which the data belongs.	Values displayed in this field are read-only.

Assets Tab

Field Caption	Data Type	Description	Behavior and Usage
Asset ID	Character	The Record ID of the Asset that is being analyzed.	This value is mapped from a query or dataset or manually entered when you create the analysis.
Last Replacement	Number	The last date or time at which the Asset failed.	Values in this column are calculated by the GE Digital APM system and are read-only. For data that contains cumulative operating time, this field is Last Replacement <Measurement>.

Data for grouped non-event based analysis

<Measurement Name> Tab

Field Caption	Data Type	Description	Behavior and Usage
Cost	Number	The cost measured at each datapoint. For grouped data, values in this column represent the amount of data (e.g., cost) recorded between that datapoint and the previous datapoint. For non-grouped data, which is used in Examples 1 and 2, the values in this field are always 1 (one). For grouped data, the values can be greater than or less than 1 (one) but must be greater than 0 (zero).	This value is mapped from a query or dataset or manually entered when you create the analysis. The name of this column depends on the measurement name you are using for your analysis.
