Define Item Class

Explanation

This activity is used to define an item class which is used for failure analysis. An item class can hold failure analysis data such as functions, fault types, symptoms, causes, failing components and corrective actions. Item classes can be arranged as a hierarchy and can inherit attributes from parent classes. Equipment objects, parts, object types, tool/equipment objects, tool/equipment types, linear asset segments, linear asset objects, segment types and linear asset types can be connected to an item class. Item classes are used for narrowing down options in the preparation and reporting stages of a work order and for failure analysis.

When used in conjunction with the RCM Analysis, the item class will be an equipment type within the process class structure on which the RCM Analysis will be performed. The resulting FMEA, Criticality Analysis and Maintenance Decisions will then propagate across your equipment register (multiple plants, systems, an offshore fleet etc.) given the equipment object’s association to the combination of process class and item class.

Prerequisites

N/A

System Effects

• An item class is created and components and functions can be connected to it.
• Object connections can be made from the item class to equipment objects, parts and object types.

To define a child item:

1. In the Failure Analysis Setup Navigator window, select the item class in the navigator on the left pane.
2. Click the Child Item Class tab.
3. Create a new record.
4. Enter values in the Item Class and Item Class Name fields.
5. Optionally, enter text in the Notes field. 
6. Save the record.

Using the Maintenance Basic Data window:

1. Open the Maintenance Basic Data window.
2. Create a new record in the Item Classes tab.
3. Enter values in the Item Class and Item Class Name fields.
4. Save the record.
5. To create a structure, use the List of Values to enter an existing item class in the Parent Item Class field.
6. Save the record.
