Constraints

Source file: origin-block-setups-constraints.htm

Constraints provide you with advanced ways to refine data.

Click Constraints > Overview on the setup configuration tab to view the constraints available for your setup. Each constraint tile includes a short description.

Note:  The list of available constraints will depend on your setup type (Equipment or Material Movement).

You can apply required constraints by clicking (Add new constraint). The constraints applied to your setup will appear on the left side of your screen, as well as under the Constraints configuration drop-down.

Constraint detailed setting screen can be entered by:

  • Clicking on the required constraint on the Applied Constraints list.

  • Selecting the required constraint from the Constraints configuration tab.

The following buttons appear on all constraints to provide unified and simplified ways of operation:

Add new constraint
Adds a new constraint to your setup. The newly added constraint is enabled by default.
Enable or disable constraint
Toggle button that allows you to enable or disable a constraint in your setup.
Delete constraint
Removes constraints from your setup.

Edit constraint name
Allows you to rename a constraint.

To rename a constraint do the following:

  1. Select the constraint whose name you want to be change and click the (Edit constraint name) button. The field with a constraint name will become active.

  2. Enter the new name and click .

    The new constraint name will be applied in the constraint main page and on the list of constraints applied in your setup.

    Note:  The default constraint name, which indicates the properties of a constraint, will remain unchanged and will still be displayed in grey colour under the changed name on the Applied Constraints list.
Clear the selected cell
Erases the data from the selected cell.
Overview Goes back to the Constraints Overview screen.

The following table provides a description of each constraint available in Origin Solid setups.
Constraints are classified as hard (), which must be obeyed by the software when it determines a schedule, or soft (), which the software aspires to meet but is not obliged to).

Constraint Hard (H) / Soft (S) Equipment (EQ) /
Material Movement (MM) setup		 Description
Maximum Active Benches H EQ, MM Specifies the maximum number of benches that can be mined simultaneously in a stage at a given point in time per period.
Stage and Waste Utility Dependency H EQ only Specifies dependencies between stage and waste areas, where waste area can only be used after a stage has been completely mined.
Stage Bench Turnover H EQ, MM Specifies the overall maximum number of benches that can be mined in a stage per period.
Stage Equipment H EQ only Allows equipment to be mapped to a stage. When the equipment is used up, the associated stages become unavailable for the rest of the period.
Stockpile Reclaim Availability H EQ, MM Flags the availability of a stockpile for automatic reclaim per period.
Waste Area Availability H EQ only Flags the availability of a waste area for material transfer per period.
Waste Area Dependency H EQ only Specifies dependencies between waste areas.
Waste Area Required Tonnage S EQ only Defines the minimum amount of waste that can be transferred to each waste area.
In-Pit Crusher Location Dependency H EQ only Specifies stage dependencies between in-pit crushers.
