ERP & MRP Planning calculator
Material Shortage Risk Calculator
Material Shortage Risk helps materials teams rank shortages so the highest production impact receives attention first.
What this calculator does
- Score material shortage risk from production impact, shortage likelihood, and shortage visibility.
- a materials manager needs to prioritize shortage actions
- It ranks material shortages by weighted production risk.
Formula used
- Material shortage risk score = production impact × 0.40 + shortage likelihood × 0.35 + visibility risk × 0.25
Inputs explained
- Production impact score: Score higher when the part stops a line, blocks shipments, or affects a bottleneck order.
- Shortage likelihood score: Score higher when supplier delivery, inventory accuracy, or demand volatility is poor.
- Shortage visibility risk score: Score higher when the shortage is hard to detect early because of poor data, late confirmations, or quality holds.
How to use the result
- Use it during ERP cleanup, MRP review, production scheduling, S&OP prep, purchasing decisions, shortage meetings, capacity planning, or daily shop-floor execution reviews.
- This is a planning estimate. Confirm final commitments against current ERP/MRP records, released BOMs and routings, inventory accuracy, supplier commitments, open work orders, quality holds, and shop-floor constraints.
Common questions
- What is the Material Shortage Risk calculator for? It ranks material shortages by weighted production risk.
- What information do I need before using it? You need impact, likelihood, and visibility risk scores.
- How should I use the result? Use it to prioritize expediting, substitutions, supplier escalation, and schedule changes.
- When is the result only an estimate? It is only an estimate when demand, inventory, lead time, routing hours, setup time, yield, supplier dates, or work-center capacity comes from forecast assumptions or stale ERP data instead of current orders and recent execution history.
