Collect Data for Reliability Distribution Analysis

To create a Reliability Distribution Analysis, you must collect the Asset ID, Failure Date, and Failure Mode information for a piece of equipment.

The following table shows the typical data needed to build a Reliability Distribution Analysis in Meridium Enterprise APM.

Data Needed	Description	Notes
Asset ID	Select a field that uniquely describes a piece of equipment, such as Equipment ID. Reliability Distribution Analyses can be conducted on any number of pieces of equipment.	This is a required field. Select a text field.
Installation Date	Select the field that contains the date on which the piece of equipment was installed.	This field is optional. Select a date field.
Failure Date	Select the field that contains the last date on which the piece of equipment failed. This data can have many different descriptions (e.g., Out of Service Date, Shutdown Date, or Failure Date).	Select a text field. This is a required field.
Failure Mode	Sometimes users put failed parts in this field, or even a description like "worn out" or "broke down". These descriptions can be very useful when deciding to include or not include a particular failure in the failure history for purposes of censoring.	Needed for Distribution Analysis only.
Downtime	If this information is available, it can be used to make the estimation more accurate. Fields like "return to service date" or "date repaired" can be used to estimate downtime.	This field is optional.
Time Units	Select the Downtime time units.
