Modern warehousing demands more than just storage—it requires speed, precision, and automation. That’s where Automated Storage and Retrieval Systems (AS/RS) come in.  At MWES, we design and integrate AS/RS buffer systems that maximize warehouse efficiency, reduce labor dependency, and keep inventory moving. Whether you need a high-density buffer for palletized goods or a fast-access solution for high-turnover items, we can tailor an AS/RS system to your facility and goals.

What is an AS/RS Buffer System?

The AS/RS buffer system consists of a high-speed shuttle that moves on a track along storage racking, where they can store and retrieve anything from small trays or totes to full-sized pallets of goods. The shuttles are controlled by a warehouse control system or a work management system that uses artificial intelligence and machine learning algorithms to make dynamic and proactive decisions for optimal system automation. This also integrates with goods-to-person order fulfillment and inventory decant stations, where operators can pick and pack orders or replenish inventory.

Key Benefits of Implementing AS/RS

Boost Throughput & Productivity

Automated Storage and Retrieval Systems (AS/RS) significantly increase operational throughput by automating material staging and retrieval. These systems can handle multiple in-and-out processes simultaneously, minimizing idle time and bottlenecks. They’re ideal for just-in-time manufacturing, where speed and precision are critical to keeping production lines moving.

Maximize Space Utilization

AS/RS solutions leverage vertical storage and compact system designs to store more inventory in less square footage. This allows you to increase storage density without expanding your facility footprint—making it easier to scale operations within existing space constraints.

Reduce Labor Costs & Improve Safety

By automating repetitive and physically demanding tasks, AS/RS systems help lower labor requirements and reduce the strain on warehouse personnel. This is especially valuable in hard-to-staff environments like cold storage or cleanrooms. Reduced forklift traffic and manual material handling also lead to a safer work environment.

Improve Accuracy & Inventory Control

Integrated with your WMS or ERP, AS/RS systems offer real-time tracking, inventory visibility, and automated material verification. This reduces picking and replenishment errors and improves overall inventory accuracy, helping you meet quality and traceability standards with confidence.

Increase Flexibility & Scalability

AS/RS systems are highly configurable to adapt to changing warehouse layouts, SKU profiles, and throughput demands. They can support advanced functions like buffer management, sequencing, kitting, consolidation, and replenishment, allowing you to scale or reconfigure operations without disrupting workflow.

Eliminate Unproductive Travel Time

AS/RS systems bring inventory to the operator, eliminating the need for manual walking or driving across the warehouse floor. This dramatically reduces travel time, which is one of the most significant contributors to labor inefficiency in traditional warehousing.

Manage Buffer Stock More Effectively

AS/RS buffers act as dynamic holding zones to ensure a steady supply of materials between upstream and downstream operations. This prevents stockouts and delays by automatically adjusting buffer levels to match real-time production demands.
