Mining Vehicle & Underground Equipment worked example

Production Capacity at 99% expected production capacity uptime: a worked example

This scenario runs the production capacity calculation on the strong side: 99% expected production capacity uptime, with every other input held at its documented default. Use it when production capacity in mining vehicle and underground equipment is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Production capacity output per cycle: 4 units / cycle (unchanged)
  • Available production capacity cycles: 480 cycles (unchanged)
  • Expected production capacity uptime: 99 % (raised for this scenario; the documented default is 90)
  • Expected production capacity first-pass yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross production capacity = production capacity output per cycle × available production capacity cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for good production capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross production capacity.
  • At this operating point the engine returns 19.2 units for production capacity downtime loss.
  • At this operating point the engine returns 57.02 units for production capacity yield loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected production capacity uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • Use it when committing delivery volumes or sizing a line for a mining-equipment order, where downtime and scrap meaningfully cut into the theoretical maximum. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good production capacity: 1,844 units (headline result)
  • Gross production capacity: 1,920 units
  • Production capacity downtime loss: 19.2 units
  • Production capacity yield loss: 57.02 units
