Sequencing processes and operations with the PERT view

The PERT view displays a graphical representation of process flow in PERT chart format. You can edit and manipulate the process flow in the graphical environment. You can also assign parts, resources, or manufacturing features directly in the PERT view.

The PERT view is used in different contexts, for example:

• When you select a process. The PERT view displays the flow of operations and processes directly under the selected process.

• When you select a work area object. The PERT view displays the physical flow on the plant floor.

• When you select an activity in the Activities view. The PERT view displays the flows of activities directly under the selected activity.

When you create a process, Teamcenter creates a default process flow that includes all the children (subprocesses and operations) of the process. The default flow appears in the structure view, starting at the top left and continuing down in a tree-like fashion, and in the PERT chart.

You can additionally add nodes to the PERT chart from siblings of the selected process.

You can additionally create flows to and from a node that is not a direct child of the selected parent node that you open as scope in the PERT chart. These types of flows are called scope flows and are displayed with a gray (configurable) background color.

Teamcenter includes this external node when creating dynamic in-process assemblies.

If the Show Assignments button is turned on, the PERT nodes provide you with information about assigned parts, resources, and features assigned to the object. If you place the mouse over the object, Teamcenter provides more information about the assigned objects. Additionally, Teamcenter displays the symbol if a process has any variant information associated, as well as incremental change icons, if applicable.

Teamcenter occasionally creates implicit flows to retain necessary dependencies between objects. This can happen, for example, when you begin with process A→process B→process C, and then configure process B out of the structure using variants. Teamcenter creates an implicit flow between process A and process C. Teamcenter displays these flows in a different color, and you cannot modify or delete them.

You can configure the attributes that determine how each process, operation, or root activity node is displayed. You can override some of these configuration settings individually.

When you select a node in the PERT chart, Teamcenter selects the equivalent line in the structure view, and vice versa. If you remove a node in the PERT chart, Teamcenter removes the equivalent line from the structure.

Tip

Use the Manufacturing - Process Sequencing perspective when you are performing sequencing tasks. This perspective already contains the required views for this task without you having to modify the layout of the Manufacturing Process Planner perspective.
