Last In First Out (LIFO) is a strategy used in material handling and storage. In the LIFO model, the most recently stored items in a location are the first taken out.
LIFO can be efficient and practical in transportation (trucks, rail cars, containers), and can be used in storage if goods do not deteriorate over time, and it saves time or cost to store and retrieve an item from one side of a storage location. LIFO is the opposite of First In First Out (FIFO).
