Batch Queue Capacity at 7.2% priority & rework contingency: a worked example

Suppose priority & rework contingency falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Batch queue capacity tells a reconditioning shop how long the current pile of tools waiting to be serviced will take to clear at the cell's real throughput.

The inputs for this scenario

  • Tools waiting in the reconditioning queue: 120 units (held at the documented default)
  • Tools cleared per hour through the cell: 12 units / hr (held at the documented default)
  • Priority & rework contingency: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base batch queue capacity time = required work รท processing rate.
  • Adjusted run time works out to 10.72 units at these inputs, and this is the headline figure for the scenario.
  • Base run time works out to 10 units at these inputs.
  • Allowance applied works out to 7.2 % at these inputs.
  • Process rate works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 units.
  • It divides the number of tools in queue by the cell's clearing rate to get base hours, then adds a contingency for rush insertions and rework loops. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Adjusted run time: 10.72 units (headline result)
  • Base run time: 10 units
  • Allowance applied: 7.2 %
  • Process rate: 12 pieces / min
