Grade Targets
Grade targets penalise the optimiser for going off-spec. The optimiser balances between positive cash flows and negative grade penalties to match blocks to destinations.
...
The Plant Agent is appearing by default in the list of Agents when configuring Cash Flows, Max Rates and Max Quantities. It is not being involved in the Expit movements, so it does not matter whether it is checked or not in the optimisation rules configuration for mining and rehandling.
Since the PlantAgent is not involved in any Expit movement, it won't consume any haulage units' hours, and doesn’t require being assigned in the Trucks Assignment step.

Flow Chart
| Tip |
|---|
The Plant Agent controls Post Crusher movements, that are not covered by Destination rules, but drawn manually in the Flow Chart step. |
...
Transactions performed by the PlantAgent are controlled by the optimization rules in the Calendar.
...
. This sort of control is optional. If not controlled in the Calendar, it will default to the upstream or downstream site items rates.

Note

|---|---|---|
In the example below, when reducing the PlantAgent’s max rate to 1000wt/h vs 5000wt/h Crusher’s rate, it creates bottleneck at the Crusher downstream since the Stockpile is getting filled faster than can be reclaimed to feed the Crusher:  | ||
It causes reduction of the material being fed to the Crusher upstream to allow for the Stockpile reclaiming at the reduced rate:  | ||
In the Destinations tab it is also visible that the stockpile is being built faster than could be reclaimed:  |
Reporting
Filter by the “PlantAgent” Agent in the Pivot report to see all material movements it controls:

Steady States
Plant Agent is not involved in expit movements. To check the transactions that it performs at a particular point in time, go to the Steady States tab.
