Overview
Schedule logic defines the relationships between different project activities.
Main parts of the project scheduling logic are listed below. Navigate through the sections below to get more detailed information.
After importing new blocks to the project, review the scheduling logic for any necessary changes.
Scheduling Mode
The scheduling engine in ATS can be run in two modes:
Constrain on Trucks uses the fleet numbers to calculate material movement.
Optimise Products uses material movement to calculate fleet numbers.
Optimise Products is the preferred option, because rehandle and blending can be auto generated as a function of ex-pit movement. When constraining by trucks, the rehandle and blending must be manually specified as calendar inputs.
Truck Constrained mode requires attention to the following Calendar values: | Optimise Products mode requires attention to the following Setup tasks: | ||
|---|---|---|---|
Equipment Numbers | Loader, truck and fleet allocations must be updated in the Calendar. | Destination Logic | Waste and Crusher Feed rules tell the engine where to apply product handling optimisation. |
Reclaim Targets | Stockpile reclaim targets must be updated in the Calendar. | Constraints | Constraints tell the agents how much to mine, and how much equipment to use. |
Product Specifications | Product rules determine the flow of material to meet blending and grade targets. | ||
Truck Constrained mode has no optimisation, that is no grade targets for making blend. It is totally driven by the user to achieve the correct blend. Therefore, in the Destination Logic, the Destination of each parcel is predefined and requires no software logic to determine the best destination to achieve the set grades or blends.
When using Optimise Products, the material you mine in the period does not get sent to a Destination until the end of the Period, it is at this point the software looks at what you have mined in the Period, excluding waste, to determine the best Destination for the material you have mined to achieve your desired Grade Targets or Blends. It is for this reason when setting up the Destination Logic you must specify all of the possible Destinations for the Ore Material in one row. That is, the material could go to the ROM or the Crusher at the end of the Period.
