现实例子
📦 Coffee Shop (Fast-Moving Item)
- • Daily sales: 50 bags of coffee
- • Lead time: 3 days
- • Safety buffer: 20%
- ROP: 180 bags
- Reorder when you drop to 180 bags to avoid running out
🎬 Electronics Store (Slow-Moving Item)
- • Daily sales: 2 laptops
- • Lead time: 14 days
- • Safety buffer: 25%
- ROP: 35 units
- Longer lead time means higher ROP to prevent stockouts
库存管理和补货
The Reorder Point (ROP) is the inventory level at which you should place a new order with your supplier. It ensures you always have enough stock to meet customer demand while your new shipment is in transit.
公式:
Your reorder point formula is simple: (Average Daily Usage x Lead Time) + Safety Stock. This prevents stockouts while minimizing holding costs.
Safety Stock is extra inventory to buffer against unexpected demand spikes or supplier delays. Retailers typically use 10-25% for fast-moving items and 20-50% for items with unpredictable demand.
💡 💡 专业提示: Adjust safety buffer seasonally. Increase it before busy seasons (holiday, back-to-school) and decrease during slow periods.
