How do you calculate a GSE delivery risk score?

Score severity, occurrence (delay likelihood), and schedule control/detection, then combine them. With severity 9, likelihood 5, and detection 5, this preset returns a weighted risk score of 6.6, high enough to flag for mitigation.

What does a high delivery risk score mean?

It means a delivery that, if late, has serious ramp or customer impact and either a real likelihood of slipping or weak schedule visibility to catch it early. Those deliveries get expediting, buffer, or escalation first.

Why is severity weighted so heavily?

Because a GSE unit that gates ramp turnaround can trigger operational penalties far beyond its build cost. A severity of 9 keeps the score elevated even when likelihood is only moderate, as in the 6.6 result.

What is the detection or schedule control score?

It rates how well your schedule signals catch a slip before it becomes a missed date. Poor visibility raises risk because problems surface too late to recover the delivery.

Risk score vs a simple late-delivery percentage, which is better?

A late-delivery percentage is backward-looking and treats every delivery as equal. The risk score is forward-looking and weights by consequence, so it prioritizes the few deliveries that actually matter to ramp operations.

How do I lower a delivery risk score?

You cannot change severity for a critical unit, so attack likelihood and detection: add schedule buffer, dual-source long-lead parts, and improve milestone tracking so slips are caught early.

Airport Ground Support Equipment calculator

Airport GSE Delivery Risk Score Calculator

The airport GSE delivery risk score is an FMEA-style ranking that flags which ground support equipment deliveries most threaten ramp readiness or customer commitments before they slip. Program and supply-chain managers in GSE manufacturing use it to triage a delivery portfolio, putting mitigation effort where a late tug or GPU would hurt operations most. It matters because GSE often gates airline or airport ramp turnaround capability, so a single high-severity late delivery can cascade into operational penalties. By multiplying severity, likelihood, and a detection-weighted control score, it surfaces the deliveries that need stronger schedule protection now.

What this calculator does

Score airport GSE delivery risk using customer impact severity, delivery-delay likelihood, and schedule detection or control strength.
a station manager, procurement lead, or GSE manufacturer needs to rank delivery risks before they affect ramp readiness
It computes a delivery risk score by combining ramp/customer impact severity, delivery-delay likelihood, and a schedule control and detection score.

Formula used

Airport GSE delivery risk score = ramp/customer impact severity × delivery-delay likelihood × schedule control and detection score
Higher scores indicate deliveries that need stronger mitigation before ramp readiness or customer commitments are affected

Inputs explained

Ramp or customer impact severity:
Delivery-delay likelihood:
Schedule control and detection score:

How to use the result

Use it during delivery and program reviews to rank which GSE shipments need expediting, buffer, or escalation.
Scores are subjective ratings, so they prioritize relative risk well but should not be read as an absolute probability of a late delivery.

Current U.S. benchmarks

Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
