TS. Steps Logic

If Destination logic tells you where material can go, Steps Logic tells you how it will get there, what intermediate steps it will go through before reaching the ultimate destination, and what equipment will be used (it is here that the fleet used is specified).

Steps Logic controls how material can move through the site during a given period. It has two potential uses:

  1. Convert a single schedule transaction into one or more final transactions (steps).

  2. Assign the fleet to each final transaction.

Steps Logic overview

Step Rules Filters

Each rule lists the Steps for transactions that match its filter criteria:

Filter

Description

Note

Filter

Description

Note

Name

Give each rule a unique name, and group in folders.

Avoid using commas in the Step Rule name, because when exporting future reports to CSV, the commas result in misalignment of the columns.

Use Rule

  • If the rule is available to be used, leave the box checked.

  • Uncheck the box to turn to disable the rule.

Period Filters

May differentiate pre- and post- plant commissioning.

Agent Filters

May differentiate autonomous and crewed tipheads.

StockpileReclaimer is a default Agent created by the software to reclaim from Stockpiles to feed the Crusher.

It doesn’t work in a pit and should be unticked from the list of Expit Agents, and used for Stockpiles Rehandle only.

 

Source and Parcel Filters

May differentiate Ex-pit from Rehandle fleets.

Agents evaluate whether the record source/parcel being mined is included in the list.

Destinations

May differentiate trucks that can use the overpass, or fit in the crusher bin. 

Note that the Destination Filter is only used to evaluate schedule transactions. To deactivate a destination, remove references to it from the Destination Logic.

Steps Logic Destination Filters have no effect on the scheduled destination. They are filters only. See the Destination Logic to change the destination.

Steps

  • Convert a single schedule transaction into one or more final transactions (steps).

  • Assign the fleet to each final transaction.

For example, the schedule transaction "Pit to Crusher" can be split into "80% direct tip, 20% rehandle" with a different fleet for each movement.

  • Waste parcels will have one Source and one Final Destination using the Pit Fleet (combined).

  • Stockpile material will have one Source and one Final Destination using the Rehandle Fleet.

    • Ore movement can have two steps:

      • From the Pit to the Stockpile using the Pit Fleet @1.0 means 100% of material follows this step;

      • From the Stockpile to the Crusher using the Rehandle Fleet.

  • The available destinations for these steps are the same as those input in the Destination rules.

Tips

  • Between the pit and the waste dump, there is one (100%) pathway, trafficked by the production fleet.

  • Between the stockpile and the crusher there is one (100%) pathway, trafficked by the rehandle fleet.

  • Between the pit and the crusher there may be: 

    • One (60%) direct tip pathway, trafficked by the production fleet.

    • One (40%) stockpile pathway, trafficked by the production fleet.

    • One (40%) rehandle pathway, trafficked by the rehandle fleet. 

  • If you type a field name (i.e. myRatio)  instead of a number (i.e. 40%) then this adds a row to the Calendar to change the ratios by period. 

  • Rules can be copied by holding down the <CTRL> key and dragging on the clipboard icon.

  • Rules can be archived and shared via the save icon and import icon in the top right of the form.

These rules can be used to split movement across multiple pathways and multiple fleets.
