The Schedule Auditor is a tool provided expressly for mine schedulers, to generate bulk haulage calculations across an entire schedule. To use this feature, you must supply an existing schedule that specifies sources, destinations, loaders, trucks and materials moved. Haul Infinity will then generate the full cycle time breakdown and 3D haul strings for each schedule record. This can be used to estimate truck fleet mobilisation and utilisation over time.
The schedule auditor requires a schedule to be imported. If you require scheduling assistance, ask us about the Alastri Tactical Scheduler.
Pre-Start Check
Inspect the schedule for errors:
Navigate to the sample data \NodesVersion folder.
Open ScheduleWithNodes.csv.
Make sure that each row in the schedule contains a source, destination, truck type, material and loader.
Remove any blank rows.
Save the schedule in a CSV format.

Schedule Import from CSV
Import to Haul Infinity:
Navigate to the sample data \NodesVersion folder.
Open SampleModelWithNodes.hinf
Find the Schedule Auditor tab below the viewport, and open it.
Click the Import Schedule button.
5. Navigate to the sample data \NodesVersion folder.
6. Open “ScheduleWithNodes.csv” file.
7. Click the blue plus icon to create a new CSV mapping template.
8. Drag and drop the CSV column headers to the corresponding schedule field. The ID and Flag fields can be left blank.
9. Click NEXT to continue.
10. Click FINISH when the import is complete.
The Sources and Destinations must exactly match between the Schedule and the Haul Infinity project. This means that for every source or destination in the schedule, there must be a node or a block that has that name. Moreover, if the schedule specifies a haul from source A to destination B, then there must a physical path on the network for a truck to travel between A and B.
Schedule Import from Scheduler
If you are using Haul Infinity within the Scheduler (ATS or APS), you can import a schedule directly from the scheduling app.
In Alastri Tactical Scheduler:
Run all the Setup Tasks.
In the Schedule tab, run Scenario or Full Schedule.
In Haul Infinity:
In the top tab bar locate the Scheduler tab.
Select “Import from Scheduler”. Imported strings will be displayed as a list in the Scheduler Auditor tab.
Double click any line in the list to animate the haul in the viewport.
Schedule Audit
Double click the first line in the schedule auditor to activate the haul in the viewport. We can use the arrow keys to move forward and backward through the schedule; this lets us inspect the haulage solutions provided by Haul Infinity and make any functional changes to the network as required.
We may at any time switch to the Charts, Truck Times and Cycle Time Analysis tabs for more detail on the active haul.
Roads can be flagged open or closed in the schedule. Use flags to model a changing road network over time.
Schedule Export
Once you have audited the schedule to your satisfaction, the calculated results can be exported for use in cost modelling and fleet selection.
To export the schedule:
Open the Schedule Auditor tab.
Click the Export Schedule button.
Navigate the samples folder.
Enter a file name, such as "schedule_export" and continue.
5. Set "Add DXFs" to "true". This will generate a 3D haul string for every row in the schedule.
7. Press NEXT to continue.
8. Wait until the data export is finished and press FINISH to exit.
The export will be saved as a zip file that contains a CSV summary and named DXFs of every haul.
Inspect the export:
Open Windows File Explorer.
Navigate to where you saved the schedule export.
Right click on "schedule_export.zip" and extract the contents.
Open "00-Summary.csv".
Every row in the schedule has been fully appended with cycle times, distance travelled, productivity rates, fuel burn and TKPH calculations.
This gives us a solid foundation on which to base decisions for cost estimation, budget forecasts and equipment mobilization.
