Overview

Fleets configured in the Fleets setup step provide a means to switch between different Truck-and-Loader groups for given Times, Locations, Materials and Destinations.

Fleets step overview

Fleets Examples

Different “Loader:Truck” combinations may be setup to work in different parts of the operation.

Common examples of Fleets that can be used in the project:

  • Production and Rehandle fleet.

  • Autonomous and Operator fleet.

  • Ore and Waste fleet.

  • North and South fleet.

  • Heavy and Light fleet.

  • Upper and lower RLs fleet.

Adding Fleets

Fleets shown in blue are automatically added for the Loaders used as Agents. Specify the Loader-Truck pairing for each of them.

Add extra fleets, ie “Rehandle”, and assign the stockpile reclaiming loader and its truck pair.

  1. Click the folder icon in the toolbar.

  2. Rename new Fleet Assignment to something meaningful.

  3. Left-click in the Loader-Truck Pairing field.

  4. The Configure dialog will opens, where:

    1. click the blue plus icon to add a loader,

    2. select the loader(s) from the Loaders dropdown list,

    3. select the truck(s) from the Trucks dropdown list,

    4. click OK.

Defining order of Loader and Fleet usage.

  • If Trucks are selected in the same rule, neither has priority. The loader may use either truck in any order.

  • If Trucks are selected in the separate rules, 1: has priority, then 2:..etc.

 The loader will use up all the trucks in rule 1: and only when these are exhausted will it look at the availability of the trucks in rule 2:.

Fleets Assignment configuration

Notes

Each of the fleets configured here will become buckets of equipment hours. The Agent dips into this bucket every time it schedules a block, depleting the hours proportionally to the production rate.

  • A single Fleet may reference multiple diggers. In this case, the user specifies the order in which the diggers are depleted (if any).

  • A single Agent may reference multiple fleets. In this case, the user specifies which fleet to use in different situations (such as Ore/Waste, Crewed/Autonomous).

For example, some sites have a crusher bin that is too narrow for the largest trucks. They use a Crusher Fleet and an Earth Moving fleet; the Agent selects the fleet appropriate to the destination in each schedule transaction.

Fleets deplete equipment in the order that they are listed.

Fleets are triggered by Agents via the Steps Logic.
