Automated Storage and Retrieval Systems (AS/RS) are advanced solutions designed to optimize the storage, retrieval, and management of inventory within a warehouse or distribution center.
Types of ASRS
| Feature | Unit Load ASRS | 4-Way Shuttle System ASRS |
| Load Type | Heavy Pallets (up to several tons) | Lighter Pallet (Maximum 2,000kg) |
| Throughput | Medium throughput; limited by a single crane per aisle | The highest throughput rate is achieved as multiple shuttles work simultaneously across all levels |
| Scalability | Scalable by adding more aisles (and more cranes) | Highly scalable/modular. Throughput is easily increased by adding more shuttles and lifter |
| Flexibility | Good; handles larger loads (unit-load) or small loads (mini-load) | Excellent; supports different load types and deep-lane configurations |
| Mechanism | A stacker crane moves both horizontally and vertically within a single aisle | Autonomous shuttles move horizontally; lifts move vertically |
| Conclusion | A mature technology, precision and reliability in handling heavy goods | Agility and modularity. It excels in high SKU environments with frequent access needs |
