Airport GSE Fleet Delivery Planner at 65% delivery release uptime: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop delivery release uptime to 65%, then walk the calculation through step by step. Estimate usable fleet delivery capacity from GSE units staged per delivery cycle, available delivery cycles, release uptime, and acceptance yield.

The inputs for this scenario

  • GSE units delivered per cycle: 6 units/cycle (held at the documented default)
  • Available delivery cycles: 18 cycles (held at the documented default)
  • Delivery release uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Customer acceptance yield: 95 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross fleet delivery capacity = GSE units delivered per cycle × available delivery cycles.
  • Usable fleet delivery capacity works out to 66.69 delivered units at these inputs, and this is the headline figure for the scenario.
  • Gross fleet delivery capacity works out to 108 delivered units at these inputs.
  • Deliveries lost to release downtime works out to 37.8 delivered units at these inputs.
  • Deliveries lost to acceptance issues works out to 3.51 delivered units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where delivery release uptime sits at 90% and the headline result is 92.34 delivered units, this scenario comes in 27.78% below the baseline at 66.69 delivered units.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to delivery release uptime, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses average uptime and yield, so it will not predict a single catastrophic acceptance stop or a supply interruption that halts a specific cycle.
