Calculation method
Calculation method
Trucks to balance observed output
ceil(a*c/(60*b))
Fleet removal capacity (m³/hour)
d*b*60/c
Unremoved volume rate (m³/hour)
max(0,a-d*b*60/c)
Fleet spare capacity (m³/hour)
max(0,d*b*60/c-a)
Symbols and units
- a
- Measured excavator output (m³/hour)
- b
- Truck usable capacity (m³)
- c
- Round-trip cycle including loading (minutes)
- d
- Scenario fleet (trucks)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Steady average cycle arithmetic; all capacities and rates measured or supplied, positive truck volume/cycle. No traffic, loading safety or dispatch optimization. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
