The Decision Tree tab contains a number of important commands for building and modifying decision tree models. You'll find commands for adding and editing nodes/instances, managing values and links, and re-building the default tree. Further, you can add or remove branch control/block and edit get/pay expressions for the model. Within the Objective & Utility group you can add or edit multiple attributes, objective function(s), and risk tolerance. You'll find that some of the same commands are also included on the Influence Diagram tab, while some are only available from the Decision Tree tab.

Decision Tree | Object | Edit | Edit the selected object (node, branch, text box, etc.). If nothing is selected, the Select Node dialog will be launched. |
 |
Decision Tree | Node | Add | Decision | Creates a new decision node in the Decision Tree |
 |
Decision Tree | Node | Add | Discrete Chance | Creates a new discrete chance node in the Decision Tree |
 |
Decision Tree | Node | Add | Value | Creates a new value that can be added to the branches of a node in the Decision Tree as a part of a get/pay expression. |
 |
Decision Tree | Node | Add | Continuous Chance | Creates a new continuous chance node in the Decision Tree |
 |
Decision Tree | Node | Add | Controlled Node | Creates a new controlled node in the Decision Tree |
 |
Decision Tree | Node | Change To | Changes the selected node to the node type indicated |
 |
Decision Tree | Node | Manage Values | Edit or delete values in the models |
 |
Decision Tree | Links | Link Events | Link events in the Decision Tree to spreadsheet driver cells |
 |
Decision Tree | Links | Manage | View/edit all the sources to which the model is linked |
 |
Decision Tree | Instance | Add Decision | Adds a new instance of a decision node to the Decision Tree, you can optionally create a new event |
 |
Model | Tree | Instance | Add Chance | <Adds a new instance of a decision node to the Decision Tree, you can optionally create a new event |
 |
Model | Tree | Instance | Add Controlled | Adds a new instance of a controlled node to the Decision Tree, you can optionally create a new event |
 |
Decision Tree | Instance | Asymmetric | Check the box to make the branches of the selected node asymmetric, un-check to make symmetric |
 |
Decision Tree | Instance | Detach | Detaches a subtree starting at the selected node |
 |
Decision Tree | Instance | Subtree | Creates a perform subtree beginning with the selected node and performed at the endpoint selected |
 |
Decision Tree | Instance | Branch Control | For the selected set of branches, choose the branch that the instance should be controlled to |
 |
Decision Tree | Instance | Sticky Control | Check this box to make the selected control settings sticky |
 |
Decision Tree | Instance | Control All | For multiple selections, control all of the branches selected to one of the settings (Low, Nominal, High, Default) in the drop-down |
 |
Decision Tree | Instance | Remove (Control/Block) | Remove branch control or block from the selected branches |
| N/A | Decision Tree | Get/Pay | See Specifying Get/Pay Expressions for information on editing Get/Pay expressions using the ribbon |
| N/A | Decision Tree | Objective & Utility | See Multiple Attributes and Objective Functions for information on editing attributes and the objective function of the model |
 |
Decision Tree | Model | Default Tree | Build or re-build the default tree, replacing the existing tree |
