Start Application

After starting the Center of Gravity application, load a configuration that you created with Data Navigator Configuration Wizard and load a dataset that you imported with Data Navigator. When you start the app, the Load Configuration dialog will pop up automatically, followed by the Load Dataset dialog.

Load Configuration

  1. Select a configuration by checking the checkbox in the Selected column.

  2. Click Load to confirm your selection.

The Load Configuration dialog can also be accessed directly by clicking on Current configuration in the status bar.

Load Dataset

  1. Select one or more dataset(s) by checking the checkbox in the Dataset Type column.

  2. Click Load to confirm your selection.

The Load Dataset dialog can be accessed directly by clicking on the dataset type in the status bar.

If you need to change your configuration, click Cancel and go back to the Load Configuration dialog to start over.


The navigation in the application is handled via the workflow panel, which is on the left side of the page, available on each page, and contains the three Center of Gravity phases. Some pages are available only when the user is in the proper phase (e.g., Scenario Details), or when some requirements are fulfilled (e.g., having a saved scenario before proceeding to phase 3).


Status bar

The status bar is an always visible part of the application, where the user can reach useful information and general functions.


From right to left:

  • Dataset Type: On the status bar we can follow which dataset(s) we are using. If the user has multiple dataset types for the configuration, these are all visible. When you want to change the dataset type, click on this element on the status bar. The Load Dataset dialog will be opened.

  • Configuration: The current configuration is visible on the status bar too. If you want to load a different configuration, click on this element in the status bar. It will open the Load Configuration dialog.

  • Scenario Results: When a calculation is executed, the total cost is visible on the status bar, both in the second and third phase. By clicking on Results Overview a dialog page opens where the user can check the main properties of the solution.

  • Scenario: You can create scenarios from the solutions that you created, or load a previously created scenario, by clicking on the scenario part in the status bar:

    • Until there is no saved scenario, the current working scenario is '(Untitled)'. After the user saved it, its name is visible on the status bar.

    • If the user changes any of the input data, a red exclamation mark red-exclamation-mark will mark that the scenario is not up to date.

    • If the user re-runs the scenario, a blue pencil blue-pencil will mark that the scenario is not saved yet.

    • When the scenario is in a changed status when you click on the scenario on the status bar, a message will pop up where you should decide whether you want to save the current data in a new scenario or load in a previous scenario.

  • Reference Scenario: In the third phase the user can load a second scenario to compare the current solution with. Just click on 'Reference Scenario' in the status bar, which is visible only in the third phase.

Load Scenario: For loading a scenario the user needs to use the proper status bar element (Scenario or Reference Scenario). Clicking on any of these will open the Scenario Overview dialog, where the user finds the main information about a scenario and a selection column. The scenario which is selected in the Select column will be loaded as Active or Reference based on which status bar element was used.


Each page has a Help side panel, where the basic information is visible about the page that is open. The user always can reach it, and when the presented information is not enough, you can use the Open Documentation button, which navigates to the proper documentation page.

Debug Export: This button opens the Debug Export dialog where you can download a file containing your current data, or containing the current configuration and dataset. The downloaded .data file can then be used by AIMMS Support for debugging.
