Fleet Dispatch Workload Calculator at 13% exception and replan allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop exception and replan allowance to 13%, then walk the calculation through step by step. Estimate dispatch workload time from mission count, dispatch processing rate, and exception or replan allowance.

The inputs for this scenario

  • Dispatched fleet missions: 2,400 missions (held at the documented default)
  • Dispatch processing rate: 18 missions/min (held at the documented default)
  • Exception and replan allowance: 13 % (the input this scenario stresses; the baseline uses 18)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base dispatch processing time = dispatched fleet missions รท dispatch processing rate.
  • Adjusted dispatch workload time works out to 151 hr at these inputs, and this is the headline figure for the scenario.
  • Base dispatch processing time works out to 133 hr at these inputs.
  • Exception and replan allowance works out to 13 % at these inputs.
  • Dispatch processing rate works out to 18 missions/min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where exception and replan allowance sits at 18% and the headline result is 157 hr, this scenario comes in 4.24% below the baseline at 151 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to exception and replan allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It models average throughput, not bursts; a fleet that meets the daily average can still back up during a 20-minute order spike.

Results at a glance

  • Adjusted dispatch workload time: 151 hr (headline result)
  • Base dispatch processing time: 133 hr
  • Exception and replan allowance: 13 %
  • Dispatch processing rate: 18 missions/min
