The Challenge of Spare Parts Inventory
Every cigarette factory manager faces the same dilemma: keep enough spares to prevent downtime, but not so many that working capital is tied up in slow-moving inventory. Here's a proven approach.
1. Classify Your Spare Parts
| Class | Criticality | Examples | Stock Level |
|---|---|---|---|
| A | Machine-stopping, long lead time | Garniture assemblies, suction bands | 2-3 per machine |
| B | Frequent replacement, short lead time | Cutting blades, garniture tapes | 1-2 per machine |
| C | Rare failure, easily sourced | Seals, gaskets, standard fasteners | As needed |
2. Calculate Your Reorder Points
Reorder point = (daily consumption × lead time in days) + safety stock
For example: If you use 1 garniture tape every 5 days on a Hauni Protos line, and lead time is 3 weeks (21 days):
Reorder point = (1/5 × 21) + 2 = 7 tapes minimum on hand
3. Consider Using a Single Source
