SMART Defining a Scenario

Any SMART simulation is defined in a two-step sequential process:

1. The definition of the dataset on which the simulation will applied;
2. The specification of the tariff change scenario and other parameters to affect the dataset;

This topic discusses Step 2.

Click on the <<Select>> link next to Scenario a new popup window opens.

You can now select existing scenarios and move them from  Available Scenarios to Selected Scenarios,  or you can define a new Scenario or modify an existing scenario by clicking on <<Add/Modify>>. This will open the Modify Scenario screen.

To modify an existing scenario check  Available Scenario radio button and select the scenario in the dropdown and click on Modify button. To modify an existing scenario without overwriting the scenario check  Available Scenario radio button and select the scenario in the dropdown and click on Save As button and enter a Scenario Name and a Scenario Description and click on Save button .To delete an existing scenario check  Available Scenario radio button and select the scenario in the dropdown and click on Delete button and confirm deletion by clicking on OK button in the confirmation screen. If you clicked Delete by mistake, click on Cancel button to cancel the delete operation. To define a new scenario ensure New Scenario radio button is checked, enter a Scenario Name and a Scenario Description and click on Add button and then perform the following steps

1. Select Beneficiary countries. Beneficiary countries are partners which export to the considered market and will be affected by the tariff reform;
2. Define Affected products. Affected products are those which tariff is changed by the scenario;
3. Define a Tariff changewhich defines how tariff are to be affected for involved beneficiaries and products and click the Proceed button;
4. Repeat the above steps if you want to include in the simulation. SMART allows including several scenarios in a single simulation. For example, a group of countries may be granted some preferential treatment while another group of beneficiaries is granted another one, or distinct groups of products may be affected by different types of tariff change, or any combination of the two preceding examples. Working with several scenarios in SMART requires some practice since the interface does not keep track of the various scenarios. A multiple scenario example will be detailed later in this document.
5. You can now select one more scenarios in the scenario selection screen.

You can now save the simulation for later submission by clicking on Save button or submit the scenario by clicking on Save and Submit button.

The next few pages will walk you through the steps for selecting Beneficiary Countries, Affected Products and Tariff Change.
