Reorder point & EOQ
Sales/day × lead time + safety stock → when and how much to order
Parameters
Reorder point = daily sales × (lead time + safety days). EOQ = √(2·D·S/H): optimal batch between ordering costs (S — logistics+paperwork per order) and holding (H — annual storage cost per unit). Average daily sales over 30–90 days, not peaks.
