Final answer:
Safety stock is an adjusted stock level that restricts stockage by serving as a buffer against uncertainties in supply and demand. It ensures that a company doesn't run out of stock when unexpected events occur. Businesses calculate the safety stock level using statistical methods and historical data.
Step-by-step explanation:
The type of adjusted stock level that restricts stockage is known as the safety stock level. Safety stock is the extra inventory that a company holds to protect against uncertainties in supply and demand. It serves as a buffer to ensure that the company doesn't run out of stock when unexpected events occur, such as delayed deliveries or increased customer demand.
To determine the safety stock level, businesses use statistical methods and historical data to calculate the average demand, lead time variability, and desired service level. By incorporating these factors, a company can maintain a sufficient stock level to meet customer needs while minimizing the risk of stockouts.
For instance, a retailer may increase its safety stock level during the holiday season to accommodate higher customer demand and potential disruptions in the supply chain.
