What do replenishment systems help manage?

Replenishment systems are designed specifically to manage stock levels and the process of restocking inventory. The primary goal of these systems is to ensure that there is an optimal amount of inventory available to meet customer demand without overstocking, which can lead to increased holding costs, or understocking, which can result in missed sales opportunities.

These systems analyze various data points, including sales trends, inventory turnover rates, and demand forecasts, to trigger restocking when inventory levels fall below a predetermined threshold. By maintaining appropriate stock levels through efficient replenishment processes, businesses can enhance operational efficiency, minimize wastage, and support better financial performance. This makes option C the correct choice, as it directly addresses the core function of replenishment systems in inventory management.
