Configuring a Legacy Value Driver Tree for Presentation
The calculation flow of a legacy value driver tree (VDT) can consist of many nodes, and
some of them may not be important for decision makers. You can create a consumption flow to
show the data from the calculation flow in a clearer and more streamlined way.
Context
After you set up the model and time period for a value driver tree and add nodes in the
Calculation tab, you can simplify the value driver tree
for presentation by specifying which nodes will appear in a story, and rearranging
links between nodes. The Consumption tab in the value driver
tree modeler shows how the value driver tree will appear in a story.
Procedure
-
From the Main Menu (), select .
-
From the list, choose the value driver tree that you want to work with.
-
Select the Calculation tab.
-
Add the nodes to the Consumption canvas by selecting a
node that you want to present and choosing either or .
Copy Node adds the individual node to the
Consumption canvas, without links to other nodes.
Copy Branch adds the node and all of its child
nodes, along with the links between them. You can add multiple copies of
each node to the Consumption tab.
You can switch between the Consumption and
Calculation tab to continue adding, removing, and
rearranging nodes for presentation.
Using the Undo and Redo
buttons, you can roll back changes made from either tab.
You can also set the Consumption canvas to display the
same nodes and links as the Calculation canvas by
selecting Reset to Calculation Flow on the
Consumption tab.
Note
If you need to delete a node in the
Calculation
tab, any copies of the node will also be removed from the consumption flow.
If it had child nodes in the consumption flow, you may need to add a link to
a new parent. Check the
Consumption tab again to add
any missing links.
-
Select the Consumption tab to arrange the nodes that you
copied.
-
To remove a node from the Consumption canvas, select the
node and choose . The node is removed, and the links to its parent and child nodes
are deleted. Select to remove the node along with its child nodes.
-
As you add and remove nodes for presentation, configure links on the
Consumption tab to ensure that the relationships
between them are easy to visualize.
You can create new links between nodes, and remove existing links. Each node
can be linked to multiple parents or children, or have no links at all.
However, you cannot create cyclical links. That is, a node cannot be linked
to another node as both a child and a parent, whether by a single link or
multiple links. For example, if you link Operating Time as a child node of
Power Use, and Power Use as a child node of Power Cost, you cannot link
Power Cost as a child node of Operating Time.
Links in the consumption flow are for visualization purposes, and do not
affect node values.
-
To create a link, select the child node, choose
(Link), and select the parent node that you want to link
to it.
-
To remove a link, select the child node, choose
(Unlink), and select the parent node that you want to
unlink.
-
Repeat steps 4 to 9 as necessary until the value driver tree in the
Consumption tab clearly shows the relationships
between significant nodes. Select
(Save) to save your changes.
