A Brief DPL Tutorial

Substituting a Get/Pay Expression for an Outcome node
We can also set up the model using a Value Node (Outcome node). This has the
advantage of not cluttering up your tree with large quantity of formulas by assigning
them to specific value nodes. In this example we will substitute both “Get/Pay”
expressions for nodes 1 and 2 for an Outcome, or Value node, which we will define in the
Influence Diagram Pane.
To do this we will create another model in this same file (we could also create a new
file).
In the Project Manager Pane:
♦ Press F12 to go to the Project Manager Pane
♦ Click on the current model (untitled)
♦ Right click with your mouse and choose “Rename” to rename the model to
“Model 1”
♦ Right click again and choose “Duplicate” to create a copy of the model. You are
instantly transported to the Model Pane. Press F12 to return to the Project
Manager Pane.
♦ Rename this new model “Model 2”
♦ Right click again on the model and choose “Make Main” 1
♦ Double click on the model to go to the Model Pane
In the Influence Diagram Pane:
♦ Click on the Value Node icon to create a Value Node.
♦ Name this node “Profits”
♦ Click on the Data tab
♦ Key in the formula for the total Profits from both years: 500*(Year1_Price–13)+
500*(Year2_Price–13). This defines profits for both years
♦ Click OK
1 Note that DPL will run the model that was last set to “main”.
