Baseline

A baseline is a snapshot of the scheduling case, as represented by tank amounts, compositions and property values, at a certain time during the scheduling period.

Baselines are useful to capture the status of the scheduling case before making changes, so that you can easily compare relevant quantities before and after the changes.

Note: AVEVA recommends that you ensure your database is up to date, by synchronizing your database using the Synchronize pane, before taking a baseline. For more details, see Multi User Collaboration.

The Baselines tab is the same as the Baselines page in the main scheduling environment.

You can use a baseline in the following ways:

• In the Settings tab, you can choose to retrieve data from the staging database since the last baseline by selecting Since last baseline from the Time drop-down menu.

• In the Charts pane (opened by clicking the Charts button in the Panes group of the Home ribbon tab) you can choose to show baseline times as vertical lines by clicking the Show baseline times icon ().

• In the Baseline tab, you can override simulated values by entering new values in the Value column.

Manage baselines

To create a baseline, follow these steps:

1. Click the button. The Add New Baseline dialog opens.

2. Clear the Active check box if you want the baseline to be inactive. You can always change the active status later.

3. In the Time field enter the date and time of the baseline in the scheduling period.

4. Enter a Name for the baseline. The default name is the date and time of the baseline.

5. Optionally, enter a Description for the baseline.

6. Click OK. The Add New Baseline window closes and the new baseline is created.

To edit an existing baseline, select it in the drop-down menu and click the button. The Edit Baseline window opens, which has the same fields as the Add New Baseline window.

To delete a baseline, select it in the drop-down menu and click the button.
