Update PERT process flows using object find numbers

Update the PERT process flow sequence of objects in a plant bill of process (BOP) using the find numbers of the objects.

You can create a PERT sequence for all child objects contained in a single selected process tree object—for example, all operations in a selected station—or you can update the PERT sequence of all descendants of a selected process tree object. You can also generate a parallel PERT sequence for objects with identical find numbers, or you can regenerate find number values from the process tree.

Procedure

1. If you have not done so already, search for and open an existing work package that contains a BOP structure, and navigate to a preferred planning task in High Level Planning or Process Planning.If your administrator has enabled line balancing using the EP_EnableLineBalancing preference, you can also navigate to the Line Balancing page.

2. In the Process panel, in the default tree view, select an object that contains descendants for which you want to generate a PERT process flow based on object find numbers.

Note The Update Flows command lets you update parallel flows in a PERT sequence. Incremental find numbers in the Process panel usually indicate a linear flow, while identical find numbers indicate a parallel flow.

Linear flows (op1 = 10, op2 = 20, op3 = 30)

Parallel flows (op6 and op7 = 30),after linear flows) (op4 = 10, op5 = 20)

3. If you are working on the Process Planning page, in the Process toolbar, click Sequence View .If you are working on the Line Balancing page, select the process resource interaction (PRI) view.

4. In the PERT sequence view, click Update Flows .

5. In the Update Flows dialog box, select the levels for which you want to update find numbers under the object you selected in step 2.

To update only those objects visible in the current sequence view, accept the default option, Visible level only.

To update objects visible in the current sequence view as well as all objects below that level, select All sub-levels.

6. If the child objects contain parallel flows and you want to avoid having to manually create them later, select the Consider Parallel Flows check box.

Depending on the sequence of flows within parallel flows, redundant flows might sometimes be created. You can delete these based on your requirements.

7. Click Update. Linear find number sequences are reflected in the flow (op1 = 10, op2 = 20, op3 = 30).Parallel find number sequences are reflected in the flow (linear op4 = 10, op5 = 20, parallel op6 and op7 = 30).
