Item Properties

Each item in the system hierarchy has properties associated with it. When an item is selected in the system hierarchy or the failure modes and reliability analysis (FMRA), you can view and edit this information on the Properties tab in the Analysis panel. The following fields may appear.

Note: The fields that are enabled in the interface and the options available in configurable drop-down lists will depend on the interface style settings that have been defined for the current project. You can choose Project > Management > Configurable Settings > Interface Style to open the Edit Interface Style (This Project) window and change the settings for the current project.

Item
- Item Name: This field is populated automatically by Xfmea based on the item’s position within the system hierarchy, but it can be changed by the user. The field cannot be blank and cannot contain any of the following characters: \ / : " * ? < > |.
- Reference Number: A reference number associated with the item.
- Version: The version of the item that the associated analyses apply to.
- Part Number: The part number of the item.
- Alternate Part Number: An alternate part number for the item.
- Item Description: A description of the item.
- Remarks: Any additional information about the item.
- Qty per System: Quantity of identical sub-items in the system (e.g., 4 engines per airplane). This value will affect the calculations performed in the failure modes and reliability analysis (FMRA).
- Qty per Assembly: Quantity of the sub-item in the next higher level assembly (e.g., 2 engines per wing).
- Supplier: The manufacturer or distributor of the item.
- Similar To: Another item similar to this one.
- Design Engineer: The name of the design engineer for the item.
- Drawing Number: The number of the drawing associated with the item.
- CAGE Code: The Commercial and Government Entity (CAGE) code associated with the item.
- LCN: The logistic control number (LCN) associated with the item.
- Reference Designator: The reference designator for the item.
- Environmental Conditions: The environmental conditions that the item is expected to operate in.
- MMEL: The item's impact on the Minimum Master Equipment List (MMEL), as used in the aircraft industry.
User-Defined Fields: Up to five text fields, two date fields, two number fields and two drop-down lists.
The Operation, Reliability and Reliability Policy fields are relevant if you wish to perform a failure modes and reliability analysis (FMRA). An FMRA can be used to a) calculate criticality metrics, b) generate a baseline system reliability based on information in the FMEA, c) share system configuration and failure mode data between Xfmea to BlockSim or d) perform RCM calculations. See Failure Modes and Reliability Analysis (FMRA).
The History fields display information about when the record was created and last modified.
