EV & Battery Manufacturing calculator
EV Supplier Shortage Risk Score Calculator
EV supply chains depend on cells, semiconductors, castings, harnesses, magnets, busbars, and thermal parts arriving on time. This calculator gives purchasing and launch teams a consistent risk score for supplier shortages that could stop production.
What this calculator does
- Score shortage risk for EV or battery suppliers using production impact, shortage likelihood, and detection weakness.
- a procurement or operations team needs to rank supplier shortages before allocating expediters, buffers, or alternate sourcing
- Returns a weighted risk score for supplier shortage prioritization.
Formula used
- Supplier shortage risk score = severity × 0.40 + likelihood × 0.35 + detection weakness × 0.25
Inputs explained
- Production impact severity: Score higher for parts that stop vehicle, pack, or cell production.
- Shortage likelihood: Use supplier capacity, delivery history, allocation, logistics, and launch readiness.
- Detection/control weakness: Score higher when warning signals, inventory visibility, or alternates are weak.
How to use the result
- Use it for launch readiness, shortage war rooms, SIOP reviews, and supplier escalation.
- Scores are subjective and do not replace inventory, MRP, supplier capacity, or logistics data.
Common questions
- What should severity reflect? Consider line-stop exposure, substitution options, safety stock, customer impact, and recovery time.
- How should occurrence be scored? Use supplier delivery history, capacity risk, allocation notices, quality holds, and logistics constraints.
- What is detection weakness? It reflects how likely the team is to miss the shortage until it affects production.
- How can I use the result? Use it to rank suppliers for escalation, safety stock, dual sourcing, or launch protection.
