Hydrogen Electrolyzer & Fuel Cell Manufacturing worked example

Supplier Shortage Risk with impact severity if this supplier misses of 4 score: a worked example in hydrogen electrolyzer & fuel cell manufacturing

Suppose impact severity if this supplier misses falls to 4 score. This page works the full calculation at that level so you can see exactly which result moves and by how much. Score the shortage risk of a critical hydrogen stack supplier (membrane, catalyst, bipolar plate, gas diffusion media, gasket) by weighting impact severity, the likelihood of an on-time miss, and the detection lead time before the line goes down.

The inputs for this scenario

  • Impact severity if this supplier misses: 4 score (the input this scenario stresses; the baseline uses 8)
  • Occurrence likelihood (on-time miss frequency): 4 score (held at the documented default)
  • Detection lead time before the line stops: 5 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Weighted shortage risk score = severity × 0.40 + occurrence × 0.35 + detection × 0.25.
  • Weighted shortage risk score works out to 4.25 score at these inputs, and this is the headline figure for the scenario.
  • Impact severity works out to 4 score at these inputs.
  • On-time miss likelihood works out to 4 score at these inputs.
  • Detection lead time works out to 5 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where impact severity if this supplier misses sits at 8 score and the headline result is 5.85 score, this scenario comes in 27.35% below the baseline at 4.25 score.
  • It computes one weighted risk score from severity (40%), occurrence (35%), and detection (25%) so suppliers can be ranked on a common scale. 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

  • Weighted shortage risk score: 4.25 score (headline result)
  • Impact severity: 4 score
  • On-time miss likelihood: 4 score
  • Detection lead time: 5 score
