An automated storage and retrieval system (ASRS) uses horizontal and vertical carousels, shuttles, or cranes to automatically move products to and from storage locations without requiring a forklift or operator to travel through the facility. The result is faster retrieval, a dramatically smaller storage footprint, reduced labor involvement, and continuous 24/7 operation—making ASRS a core technology for high-volume distribution centers and manufacturing facilities managing large inventories in limited space.

By eliminating the wide aisles required for forklifts and reducing reliance on floor-level storage, ASRS solutions maximize both vertical and horizontal space utilization. High-density storage configurations can place significantly more pallet or unit positions within the same building footprint—freeing floor space for other operational functions and removing the need for facility expansion to accommodate inventory growth.

Each is designed for a different load type and throughput requirement. Unit load systems handle standardized loads—typically full pallets—moving them quickly in and out of high-density storage. Mini load systems store smaller parts and products in the mid-range of activity, offering fast performance in a compact footprint. Pallet shuttle systems use deep storage lanes and automated shuttles to store and retrieve full pallets, reducing the number of forklift movements required and maximizing density in block storage applications.

In traditional picking, operators travel to the product. Goods-to-person reverses that—the system automatically delivers the required items to a stationary operator, who sees exactly what to pick on a digital screen. This eliminates travel time between pick locations, reduces physical fatigue, and improves accuracy. It’s particularly effective in e-commerce and high-SKU environments where order profiles are small, frequent, and highly varied.

Yes. Vertical lift modules (VLMs) and vertical carousels are compact, automated storage systems designed for small-to-medium-sized parts and products. A VLM uses two columns of trays with an extractor that delivers the selected tray to the operator, ideal for ceiling heights over 25 feet and items with varying dimensions. Vertical carousels rotate bins on an oval track to bring the desired bin to the operator—better suited for ceiling heights under 25 feet with more uniform part sizes. Both dramatically increase storage density and operator productivity compared to traditional static shelving.

ASRS works best in operations experiencing space constraints, high inventory volumes, labor challenges, or accuracy issues with manual picking—particularly in distribution centers and manufacturing facilities with consistent, high-throughput requirements. Malin’s approach is to analyze and optimize the operation first, using the Raymond Lean Management System to assess workflows before recommending any automation investment. This ensures ASRS is applied to an already-efficient process, maximizing the system’s return and avoiding the cost of automating avoidable inefficiencies.

ROI varies based on facility size, current labor costs, inventory volume, and the specific system implemented. The primary financial drivers are labor cost reduction, space savings (which can eliminate the need for facility expansion), reduced product damage from automated gentle handling, and inventory accuracy improvements through RFID tracking that reduce physical count labor. Malin’s engineering team develops ROI models as part of the design process, giving operations a clear picture of expected payback timelines before committing to an investment.
