Tutorial: Create a model

This chapter shows you how to:

Create a new model
Create new variable nodes and enter attributes
Move and delete variable nodes
Draw influence arrows to define dependencies between variables
Define variables as explicit values, functions and lists
Invoke a built-in function to define a variable
Do a simple Parametric Analysis

This chapter shows you how to create a new Analytica model.

In the process of building a model to analyze the costs of owning and operating an automobile, you will create variables, define dependencies, add documentary text, and compute results.

If Analytica is not open, start it by double-clicking its icon. If Analytica is already open with an active model go to the file menu, select close model, then select new model.

Creating a new model

When you start up a new Analytica session it shows an Object window for an untitled model. Behind the Object window you will see an empty Diagram window.

First you should enter a Title for your model:

Click in the Title attribute field (to the right of Title). Type in Car cost model and press Alt- enter. In the space just above the Title you entered, you will see that the Identifier field automatically changes to Car_cost_model.
Press Tab to go to the Description attribute and type in:

A demonstration model to show how to calculate the cost of running a car
