Specify Min | Limits minimum ratio of the material fed from the Source to the Destination.
|  | ||
Specify Max | Limits maximum ratio of the material fed from the Source to the Destination. |  | ||
 | ||||
Specify Target | Specifying target also introduces “Content Deviation Penalty” input row in the Calendar. The difference between the Actual and the Target blend is subject to this Penalty multiplier specified by the user. The Penalty is summed with the Cash Flows to determine the reward or cost of blending materials into each Destination. The higher the deviation penalty, the better the optimizer will try to meet the target, but it may not be achieved due to other cash flows and objectives. |  | ||
Show Tram Lines | Displaying additional guidance rows for the optimisation rule in the Calendar. Used for visual purposes only to change the color of values in the “Actuals” field, i.e. if it goes out of range by more than 0.0001 it goes red, less than orange, otherwise it's black. |  | ||
Numerator and Denominator | Blend ratios are calculated using a Numerator and Denominator, as such the setup requires both to be populated.
|  | ||
Destinations | The Destination(s) to which the blend target is applied. |  | ||
Quantity Field | The field to which the blend target is applied.
|  | ||
Sources | The Source(s) for Numerator and Denominator to which the blend target is applied. | |||

Grade Lower Limit | The final weighted average grade cannot be below this value.
| Grade Limits applied to Product Specifications > StockpileGradeTarget are the weight average of the material added to the Stockpile over a Period. They are not equal to the grades of the stockpile closing balance. |
Grade Upper Limit | The final weighted average grade cannot be above this value.
| |
Grade Target | The difference between the Actual grade and the Target grade is subject to a penalty multiplier specified by the user.
If Crusher A and Crusher B have different grade targets, then a single block will incur a different penalty depending on the destination. This penalty is summed with the Cash Flows to determine the reward or cost of blending materials into each destination. | |
Content Deviation Penalties | The value of the content deviation penalty should be considered relative to other grades, and relative to the Cash Flow values.
