Tool Sharpening, Reconditioning & Industrial Repair Services worked example

Batch Queue Capacity at 12% priority & rework contingency: a worked example

This scenario runs the batch queue capacity calculation on the strong side: 12% priority & rework contingency, with every other input held at its documented default. Use it when batch queue capacity in tool sharpening, reconditioning and industrial repair services is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Tools waiting in the reconditioning queue: 120 units (unchanged)
  • Tools cleared per hour through the cell: 12 units / hr (unchanged)
  • Priority & rework contingency: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base batch queue capacity time = required work รท processing rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 units for adjusted run time, the number this scenario is built around.
  • At this operating point the engine returns 10 units for base run time.
  • At this operating point the engine returns 12 % for allowance applied.
  • At this operating point the engine returns 12 pieces / min for process rate.

How this compares with the baseline

  • Against the tool's baseline example, where priority & rework contingency sits at 10% and the headline result is 11 units, this scenario comes in 1.82% above the baseline at 11.2 units.
  • Use it in daily WIP reviews, when quoting turnaround on a full queue, or to decide whether to add capacity or overtime. 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

  • Adjusted run time: 11.2 units (headline result)
  • Base run time: 10 units
  • Allowance applied: 12 %
  • Process rate: 12 pieces / min
