Demand Forecasting
Seasonal Decomposition Approach
- Separate trend, seasonality, and irregular components (STL decomposition)
- Apply seasonal indices:
Seasonal Index = Average for period / Overall average
- Forecast base trend, then multiply by seasonal index
- Adjust for known events: promotions, product launches, macro shocks
Inventory Optimization
Economic Order Quantity (EOQ)
EOQ = √(2 × Annual Demand × Ordering Cost / Holding Cost per unit)
Where: Holding Cost = (% of unit cost per year) × unit cost
Safety Stock
Safety Stock = Z × σ_lead_time × √(lead_time) + Z × lead_time × σ_demand
- Z = 1.65 for 95% service level, 2.05 for 98%, 2.33 for 99%
Reorder Point
ROP = Average Daily Demand × Lead Time + Safety Stock
ABC Analysis
| Category | % of items | % of value | Action |
|---|
| A | Top 10% | ~70% of value | Tight control, frequent review, accurate forecasts |
| B | Next 20% | ~20% of value | Moderate control, regular review |
| C | Bottom 70% | ~10% of value | Minimal control, simple replenishment rules |
Supplier Risk Scorecard
Score each supplier (1-5) on:
- Quality: defect rate, return rate, audit results
- Delivery: on-time delivery %, lead time reliability
- Financial stability: credit rating, public financial health
- Geographic risk: single country exposure, geopolitical risk
- Concentration: % of your spend with this supplier
Concentration risk flag: single supplier > 30% of category spend
Disruption Stress Test Scenarios
- Single-source supplier fails: what's the impact and how quickly can you qualify an alternate?
- Port disruption: 6-week delay on all ocean freight from a region
- Demand spike: +40% demand with 0 advance notice
- Raw material shortage: key input unavailable for 90 days
- Logistics cost shock: freight rates triple overnight
