SAMM Concepts and Mechanics

This page introduces the concepts and mechanics required to navigate and use a model in the SAMM (Scenario and Model Management) software, a component of the whatIf? Modelling Environment.

Instructional YouTube videos are embedded throughout the tutorial. The videos are also compiled in a single YouTube playlist (alternative Dropbox folder).

Connecting to a Server

  1. From All Programs | whatIf, start SAMM (Scenario and Model Manager).
  2. The Connect dialogue box will appear. Enter the Server, Port and account credentials information as provided by your administrator and click Connect. The Connect dialogue is shown below - note that you may be required to use a different port number.
  3. If a connection is successfully established the Model Families window will appear, listing all items available to you.

An input (or control) variable can be assigned a specific value, or instance. Variables may have multiple instances. The concept of multiple variables each having multiple instances is shown here:

A scenario is a set of instances for all the input variables in a model framework, along with the associated values for the output variables. The concept of multiple scenarios and how they relate to variables and instances is shown here:
