Probability Distribution Analysis Data Model

The following diagram shows how the families used in Probability Distribution Analysis are related to one another.

Note: In the diagram, boxes represent entity families and arrows represent relationship families that are configured in the baseline database. You can determine the direction of the each relationship definition from the direction of the arrow head: the box from which the arrow originates is the predecessor, and the box to which the arrow head points is the successor.

In the above image, the Distribution box represents one of four Distribution subfamilies in which records can exist: Exponential, Lognormal, Normal, or Weibull.

As you develop a Probability Distribution Analysis, you will create records in these families and link them together, either manually or automatically via the options in the GE Digital APM Framework. Throughout this documentation, we use the term Probability Distribution Analysis to mean the combination of the Distribution record and all the records that are linked to it.

About Site Filtering in Probability Distribution Analysis

In Probability Distribution, the site is assigned based on the user's selection in the Site control, but the data for the analysis can be generated by a query that contains records from multiple sites.

Tip: For more information, refer to the Site Filtering section of the documentation.
Note: Reloading the data will re-run the query, limiting the results displayed to the data points based on those to which the single-site user has access.

Analyses that are created for a single site and that are based on a query containing multi-site data will contain multi-site data. A single-site user with access to the analysis can open the analysis and view all of the multi-site data in an analysis.

Note: Probability Distribution does not create a link between the analysis and the asset(s) in the data the analysis is based on.
Tip: To prevent analyses from being modified by other users, save the query on which the analysis is based to a personal or private folder.

Consider an organization that has three sites, Site X, Site Y, and Site Z. The following Probability Distribution records exist:

  • Probability Distribution A: Assigned to Site X
  • Probability Distribution B: Assigned to Site Y
  • Probability Distribution C: Assigned to Site Z
  • Probability Distribution D: No site assigned (global record)

Scenario 1: User assigned to only Site X

This user will see Probability Distributions A and D.

Scenario 2: User assigned to both Site X and Site Y

This user will see Probability Distributions A, B, and D.

Scenario 3: Super User

This user will see Probability Distributions A, B, C, and D.

Important: If a Super User modifies the site assignment of a child record from the site assignment that it inherited from a parent record, data integrity will be compromised.

Distribution Data for a Probability Distribution Analysis 

The following table contains a list of fields available on the Probability Distribution Data window for a Probability 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. For more information, refer to the Site Filtering section of the documentation.

FieldData TypeDescriptionBehavior and Usage
Censored Logical

A value that indicates whether or not the datapoint is excluded as a failure but included in the operating time of the Asset.

Select the check box if you want to censor the data on the selected row.
Datasheet CharacterA link that displays the datasheet associated with the failure event. If you have the appropriate privileges, after you select the View link, you can edit the data and select Save to save any changes. This column appears only when a query is the data source for the analysis.
Ignore LogicalA value that indicates whether or not the data on the selected row is excluded from the analysis calculations and plots.

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.

Note: A minimum of three datapoints is required to perform a calculation. If you exceed the maximum number of ignored datapoints, the application will display a warning message after you select OK. The events marked as ignored will not appear on the plots.
Remarks TextComments about the event.You can enter a value manually in the box.
X NumericThe value of the random variable. This value can be mapped from a query or dataset using the or manually entered when you create the analysis.

About Data Mapped to the Baseline Analysis <Source Type> Window

When you create a Probability Distribution Analysis from a query or dataset, the Probability Distribution Builder window will prompt you to map values from columns in the query or dataset to certain values in the Probability Distribution Analysis. The values that you select to map on the Select Data Fields screen in the Probability Distribution Builder window will then appear in the associated columns in the Baseline Analysis <Source Type> window. The <Source Type> is Query or Dataset on which your analysis is based.

Note: If the analysis is based on a query or a dataset and contains additional columns that are not mapped to columns in the analysis dataset, those columns will appear in the Baseline Analysis <Source Type> window with the column name in parentheses.

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. For more information, refer to the Site Filtering section of the documentation.

The following table provides an alphabetical list and description of the fields that exist for the Reliability Recommendation family. The information in the table reflects the baseline state and behavior of these fields. This list is not comprehensive.

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.
