In a continuous replenishment strategy, the customer remains the sole decision-maker regarding order quantities. This strategy involves the supplier continuously replenishing inventory based on actual sales data provided by the customer, such as point-of-sale data. While the supplier manages the timing and quantity of replenishments to ensure that inventory levels are maintained, the ultimate decision on how much to order rests with the customer. This ensures that the customer's needs and preferences are directly reflected in the inventory levels.References:
