Robot Pick Rate at 61% expected cell efficiency: a worked example

This worked example runs the robot pick rate numbers for a tougher week than the baseline: 61% expected cell efficiency instead of the typical 85%. Estimate sustained robot pick rate in picks per hour from logged picks, runtime, and a realistic cell efficiency.

The inputs for this scenario

  • Picks completed in the window: 28,800 picks (held at the documented default)
  • Cell runtime measured: 8 hr (held at the documented default)
  • Expected cell efficiency (uptime x quality): 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Pick throughput = picks completed / cell runtime.
  • Sustained robot pick rate works out to 2,196 picks / hr at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 3,600 picks / hr at these inputs.
  • Expected cell efficiency works out to 61 % at these inputs.
  • Cell runtime works out to 8 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected cell efficiency sits at 85% and the headline result is 3,060 picks / hr, this scenario comes in 28.24% below the baseline at 2,196 picks / hr.
  • Use it when validating a vendor's cycle-time claim, sizing a cell to a takt requirement, or converting an observed pick count into a plannable hourly rate. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Sustained robot pick rate: 2,196 picks / hr (headline result)
  • Raw throughput: 3,600 picks / hr
  • Expected cell efficiency: 61 %
  • Cell runtime: 8 hr
