Running the Variation experiment

You should create at least one scenario to run the Variation experiment. 

Prior to running the experiment you must specify the scenario to work with, define the variations and select statistics to collect the data for. 

When you launch the experiment, it passes through a series of iterations, one for each variation. When the experiment is finished, you can compare the values of the statistics collected for each variation to view how the differences in the initial conditions affect the model behavior.

To run the Variation experiment
  1. Click the SIM tab located in the top left area of ALX workspace, and select the scenario to work with.
  2. Navigate to the experiments section and select Variation experiment.
    The GIS map will be substituted with the experiment parameters.
  3. Set the experiment start and end dates in the Experiment duration section.
  4. If needed, turn on the use of replications by clicking the Use replications toggle button. Specify the required number of replications in the Replications per iteration field.

  5. Define the Variable parameters of the scenario parameters.

    To add a variable parameter, click the Add button in the Variable parameters section and provide the following values in the fields of the opened dialog box:

    Note: Variation is set for a single parameter. If you need to vary several parameters during the experiment, you must create a separate variation for each parameter.

  6. Configure statistics that will be collected during the experiment execution:
  7. Click Run to start the experiment execution.

    Note:If you are currently running one or more experiment(s) of any type, a warning message will pop-up, notifying you about the number of currently running experiments.

  8. Observe the collected data in the form of a table in the Variation results tab.
