How do you calculate a GSE supplier shortage exposure score?

Multiply the three scores together: shortage impact severity times supplier shortage likelihood times detection-and-mitigation score. In the example 9, 6, and 4 combine to an exposure score of 6.7 on the tool's scaled output.

What do the three input scores mean?

Severity is how badly a shortage hurts builds or repairs, likelihood is how probable the shortage is, and detection/mitigation is how poorly you would catch or cushion it. Higher detection scores mean weaker safeguards, which raises exposure.

What is a high exposure score?

Because the score is a product, it climbs fast when all three drivers are elevated. Rank parts by their relative scores rather than a fixed threshold and concentrate mitigation on the top of that ranked list.

Why does worse detection raise the score?

In this FMEA-style model a high detection-and-mitigation score means you are unlikely to catch the shortage early or soften it — so weak safeguards increase exposure, mirroring how detection works in classic risk priority numbers.

How do I lower a part's exposure score?

Attack whichever driver is highest. Dual-sourcing cuts likelihood, holding safety stock cuts severity impact, and supplier scorecards or earlier signals improve detection — each pulls the product down.

Should I act only on the highest scores?

Start there, but also watch high-severity parts even when likelihood looks low, since a single sole-source casting failure can ground a GSE build line regardless of how improbable it seemed.

GSE Supplier Shortage Exposure Score Calculator

GSE Supplier Shortage Exposure Score is an FMEA-style risk priority metric that ranks which parts and suppliers most threaten ground support equipment builds and field repairs. Supply chain and procurement leads in GSE manufacturing use it to decide where to hold safety stock, dual-source, or accept the risk. By multiplying how bad a shortage would be, how likely it is, and how well it can be detected and mitigated, the score surfaces the suppliers that deserve attention before a stockout grounds a build line or strands a field repair. It turns a fuzzy gut feeling about supply risk into a comparable number across a parts portfolio.

What this calculator does

Score supplier shortage exposure for airport GSE builds using ramp or delivery impact, shortage likelihood, and detection or mitigation strength.
a procurement manager needs to prioritize shortage mitigation for critical GSE parts or suppliers
It multiplies shortage impact severity, supplier shortage likelihood, and a detection-and-mitigation score into a single exposure score for ranking supply risk.

Formula used

GSE supplier shortage exposure score = shortage impact severity × supplier shortage likelihood × shortage detection and mitigation score
Higher scores indicate parts or suppliers that need stronger mitigation before GSE builds or field repairs are affected

Inputs explained

Shortage impact severity:
Supplier shortage likelihood:
Shortage detection and mitigation score:

How to use the result

Use it when prioritizing which GSE parts or suppliers need dual-sourcing, safety stock, or contractual protection.
Scores are relative ranking tools, not probabilities; a high number flags attention but does not predict when or whether a shortage occurs.

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).
