Creating a new scenario

About this task

You can change your input data to examine the effects on the model. As mentioned, this could take the form of excluding hot dog from the solution to generate a vegetarian variant of the diet.


  1. Click the Scenarios icon Scenarios icon to open the Scenario panel.
  2. Use the Create Scenario drop-down menu to create a new scenario from the current one.
  3. Add a name for the duplicate scenario and click Create.
  4. Working in your new scenario, in the Prepare Input Data view, open the diet_food data table in full mode.
  5. Locate the entry for Hotdog at row 9, and set the qmax value to 0 to exclude hot dog from possible solutions.
  6. Switch to the Model view and run the model again.
  7. You can see the impact of your changes on the solution by switching from one scenario to the other.


The vegetarian variant of the diet excludes hot dog from the solution but adds raisin bran and adjust quantities of other foods.

In the Dashboard, the solution is displayed for the current scenario in the Solution page. To add another chart to display the previous scenario, click the Chart icon and then edit it. In the chart widget editor that opens, give this chart a name and select Scenario 1 from the Add scenario drop-down menu in the Scenarios section and remove Current Scenario. Select solution in the Table section. Close the Chart Widget Editor to save your updates. You now have two bar charts displaying the two scenarios in your dashboard.

You can change the type of chart and its display attributes. For example, to see the raisin bran in the bar chart, change the width to 1000 in the JSON tab of the Chart widget editor.
