How LIFO Works in Warehouse Management
The LIFO method operates on the principle of prioritizing the newest inventory for outbound shipments. When goods arrive at a warehouse, they are positioned for immediate access, meaning they will be picked and shipped before older stock that arrived earlier. This creates a system where the first items to enter storage become the last to leave, hence the name Last In, First Out.
Primary Applications and Benefits
LIFO is mainly used to value a company’s stock with a view to increasing financial results. This is particularly relevant when the oldest products generate value over time. A prime example includes alcoholic beverages requiring aging in cellars, where older inventory becomes more valuable and should be preserved longer.
The method offers several key advantages:
- Provides the most current production pricing, as recently received goods reflect up-to-date market costs
- Ensures older stock remains in storage until newer inventory is depleted
- Ideal for products without use-by dates, such as construction materials or dry goods from the agri-food industry
- Maximizes space efficiency by utilizing single storage racks for loading and unloading
Storage Solutions and Warehouse Design
LIFO management allows for channel storage, which significantly saves space in both floor area and vertical height. This configuration reduces travel distances for machine operators and forklift users, as loading and unloading processes occur at the same location. AR SHUTTLE routes are also optimized since goods enter and exit from identical positions.
The system works best with shuttle-based item location, as shuttles typically contain one reference at a time. Racks are most often adapted to goods managed in large quantities, of similar sizes, and presenting low turnover rates.
Structural Advantages
Storage facilities using LIFO can eliminate traditional aisles by placing racks adjacent to one another, improving density. The warehouse can be designed to receive one known reference per loading aisle, with two primary loading solutions available: drive-in options with single access points, or drive-through configurations offering multiple access points. This setup simplifies input and output control while maximizing available storage capacity.
