WMS, Warehouse Labor & Fulfillment worked example

Picking Zone Balance at 99% pick equipment and labor uptime: a worked example

This scenario runs the picking zone balance calculation on the strong side: 99% pick equipment and labor uptime, with every other input held at its documented default. Use it when picking zone balance in wms, warehouse labor and fulfillment is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Lines picked per zone cycle: 4 units / cycle (unchanged)
  • Available pick cycles per zone in the shift: 480 cycles (unchanged)
  • Pick equipment and labor uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass pick accuracy: 97 % (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where pick equipment and labor 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 balancing labor across pick zones, sizing a wave, or diagnosing why one zone consistently falls behind the pack line. 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 picking zone balance capacity: 1,844 units (headline result)
