What is the name of the inventory system that maintains stock by established levels?

The inventory system that maintains stock by established levels is known as the Periodic Automated Replenishment System. This approach involves setting predefined levels of stock for each item, and when the inventory falls below these levels, the system automatically triggers an order for replenishment. This method helps to ensure that there is always an adequate supply of necessary items on hand, facilitating efficient operations and minimizing the risk of stockouts.

The periodic nature of this system allows for regular checks of inventory levels, ensuring that items are restocked in a timely manner according to established thresholds. This is particularly effective in healthcare environments, where having the right supplies available is critical for patient care and safety.

In contrast, just-in-time inventory focuses on minimizing stock levels and timing orders closely to the rate of consumption. The fixed order quantity system is less about maintaining established levels and more about setting a specific quantity to reorder whenever stock reaches a predetermined point. Stockless inventory systems reduce the amount of inventory held but might not adhere to established stock levels since they aim to receive supplies just as they are needed, often relying on vendor agreements and efficient supply chain operations.
