About the Structure Tree

The Structure Tree displays the system to be analyzed with the similar expandable structure as in the authoring tool. Depending on the associated templates, some created Reliability, Availability, Maintainability, Safety (RAMS) objects are added to the Structure Tree.

Description

The system to be analyzed can be a product or a process.

The corresponding structure is displayed in an immersive panel, which can be moved, resized, and docked to the widget.

The Show/Hide Failure Modes command lets you display or hide failure modes inserted in the tree.

Elements

Expanding the nodes in the Structure Tree reveals:

  • The subcomponents of any component.
  • The FMEAs associated with a component.
  • The functions the component implements either directly or in context for a logical reference, the child products for physical reference, or the operations for a process.
Note: If the elements are revised, their names are appended with the revision number. If an associated table is revised, all the revisions are presented in the Structure Tree.

The following elements can appear in the Structure Tree:

Logical or Physical Reference
For a Design FMEA, the logical system architecture or physical system architecture is the backbone of a study. Open at least one logical reference or physical reference to start an FMEA. The root architecture reference is displayed, along with its children instances. The FMEA elements point to different parts of this architecture.
General or Workplan System
For a Process FMEA, the general system or the workplan system is the backbone of a study. Open at least one general or workplan system to start an FMEA. The FMEA elements point to different parts of the hierarchy of workstations and operations.
RAMS Objects
The following icons represent the Reliability, Availability, Maintainability, Safety (RAMS) objects and are displayed in the Structure Tree.

Other Elements
If requirements are assigned to functions or operations, these requirements are displayed as children of these functions or operations in the Structure Tree. For these requirements, all the elements, such as failure modes, severities, controls, which are handled in the causality relationships appear nested in the Structure Tree. For more information, see Creating or Selecting a Requirement.
Calculated attributes do not appear in the Structure Tree.

Customized Labels

By default, the labels of PLM objects are based on the identification of components of the system by listing the elements of the hierarchy of subsystems and components. The Administrator can customize these labels.
