Digital Dispatch Adherence at 63% expected line availability: a worked example

Suppose expected line availability falls to 63%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate achievable good units per shift when dispatching work orders digitally, factoring in planned output, dispatch cycles, line availability, and first-pass yield.

The inputs for this scenario

  • Planned good units per dispatch cycle: 50 units / cycle (held at the documented default)
  • Dispatch cycles released per shift: 8 cycles / shift (held at the documented default)
  • Expected line availability: 63 % (the input this scenario stresses; the baseline uses 88)
  • Expected first-pass yield: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross shift capacity = units per cycle x dispatch cycles per shift.
  • Good units per shift works out to 239 units at these inputs, and this is the headline figure for the scenario.
  • Gross shift capacity works out to 400 units at these inputs.
  • Availability loss works out to 148 units at these inputs.
  • First-pass yield loss works out to 12.6 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected line availability sits at 88% and the headline result is 334 units, this scenario comes in 28.41% below the baseline at 239 units.
  • It computes good units per shift from units per dispatch cycle, cycles per shift, line availability, and first-pass yield, and breaks out the availability and yield losses. 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

  • Good units per shift: 239 units (headline result)
  • Gross shift capacity: 400 units
  • Availability loss: 148 units
  • First-pass yield loss: 12.6 units
