Optimization Tasks

Long-term planning controls and dialogs

Tasks Pane - Optimization

To access this panel:

  • Display the Tasks Pane, then select [Optimization] from the panel selection drop-down list

The Optimization panel displays the list of commands in the top-bottom order you will normally follow to complete the project.

Generally, tasks are only available if expected inputs are available (e.g. you cannot schedule pushbacks without an economic model).

  • Back, Forwards and Home: use these commands to go forward and back through your panel viewing history. This can be useful to quickly move between two regularly-used panels, for example.
  • Panel selection: use this drop-down menu to select a tasks panel (Optimization, Visualize, Reports or Notes).
  • Scrollers: If the Tasks Pane is taller than the current screen resolution, use these arrows to scroll the pane contents up or down.

Commands are grouped into collapsible tables, each representing a key functional area of the strategic planning and optimization workflow.

    • ClosedDatamine Surface...

      Import one or more wireframes for use in optimization. This option is used to select a Datamine wireframe triangles file.

      After a file and attributes have been selected for import, the Save Surface dialog is used to migrate the data into the current database.

    • ClosedOther Surface...

      Import one or more wireframes for use in optimization. This option is used to activate Datamine's Data Source Drivers console and select a non-Datamine file (a wide range of formats are supported).

      After a surface file and attributes have been selected for import, the Save Surface dialog is used to migrate the data into the current database.

    • ClosedBoundaries...

      Boundary strings representing pit limits, slope regions, pushback adjustments or pit partitions are imported using this command.

      Once a string and attributes have been selected, you assign the data to a particular category using the Choose Region Type dialog
