Preguntas frecuentes

What is the reorder point?
It's the inventory level at which you should place a new order. It's made up of expected demand during the lead time plus a safety stock.
How is it different from safety stock?
Safety stock is only the buffer against variability; the reorder point adds it to average demand during the lead time to tell you when to reorder.
