Cycle Time Calculations
Haul Infinity calculates cycle times from first principles using the payloads, swing times, and in-cycle delays.
...
Loader Payload Calculation
Enter the bucket payload and volume limit.
Haul Infinity calculates the utilized bucket payload.
Truck Payload Calculation
Enter the truck tray payload and volume limit.
Haul Infinity calculates the utilized tray payload.
Loading Calculation
Enter the truck filling type:
“FullBuckets” → less swings to fill the tray, some trucks light-loaded.
“FullTrucks” → more swings to fill the tray, last bucket light-loaded.
“Theoretical” → allow the digger to make "half a swing".
Enter the loader cycle time (time to load one bucket).
Enter the loader first pass delay (time to switch between trucks).
Haul Infinity calculates the corresponding load times.

Overrides
The Overrides section can be used to bypass the cycle time calculations.
...
Make sure to override both Loader Load Time and Truck Load Time to capture the correct truck and loader rates.
Truck Matching Type
Select the truck matching type:
...
Tactical Scheduler users are recommended to use “Theoretical” matching for scheduling.
Queue Time
If queue time is already accounted for in the Time Usage Model, then set:
...
This removes queue time from the Haul Infinity cycle times.
Truck Spot Time At Loader
Enter the truck spotting time for each loader type.
Dumping Time
If the historical truck dumping time includes the dump spot time, be sure to zero the "SpotAtDumpSeconds" property in Crusher/Stockpiles nodes on the network.
