Automated Warehouse Systems: Transforming Fulfillment Operations
In the fast-evolving world of e-commerce logistics, automated warehouse systems have become the defining factor between fulfillment providers that merely keep up and those that lead the industry. As order volumes surge and customer expectations for speed and accuracy intensify, manual warehouse operations are no longer sustainable for brands that want to scale. The solution lies in intelligent automation — and at the forefront of this revolution are Knapp’s automated storage and retrieval systems, including the OSR Shuttle™, FourWay, and TwoWay technologies.
At FulfillmentTR, powered by AKA Technic, we have invested heavily in these cutting-edge systems at our state-of-the-art Bursa facility. This guide provides a comprehensive look at each system, how they work, their unique advantages, and how they come together to deliver 99.9% order accuracy and same-day shipping for brands selling in Turkey and beyond.
Understanding Goods-to-Person Automation
Traditional warehouse operations rely on a person-to-goods model, where workers walk through aisles to locate, pick, and transport items. This approach is time-consuming, physically demanding, and prone to human error. As SKU counts grow and order volumes increase, the inefficiencies multiply exponentially.
Goods-to-person (GTP) automation flips this model entirely. Instead of workers traveling to products, the products travel to workers. Automated systems retrieve items from high-density storage and deliver them directly to ergonomic pick stations. This paradigm shift delivers:
- Dramatically faster pick rates — up to 5x improvement over manual operations
- Near-perfect accuracy — system-guided picks eliminate mislocation errors
- Reduced labor requirements — fewer operators handle significantly more volume
- Optimized space utilization — high-density storage reduces warehouse footprint needs
- Consistent throughput — automation doesn’t fatigue, ensuring steady performance across shifts
OSR Shuttle™: The Heart of Intelligent Order Fulfillment
How the OSR Shuttle™ Works
The OSR Shuttle™ by Knapp is a goods-to-person system designed specifically for high-performance order fulfillment. It operates within a multi-level racking structure where autonomous shuttle vehicles move along rails on each level, retrieving and storing totes (containers) that hold individual products or product groups.
Here is the operational flow of the OSR Shuttle™ system:
- Storage: When inventory arrives and is processed at the inbound station, items are placed into standardized totes. The system assigns each tote an optimal storage location based on demand frequency, size, and velocity data.
- Retrieval: When an order is received, the warehouse management system (WMS) identifies which totes contain the required items. Shuttle vehicles on the corresponding levels retrieve these totes and transfer them to vertical lifts.
- Delivery: Vertical lifts transport the totes to the pick station level, where they are presented to an operator via conveyor systems. The operator picks the required quantity, confirmed by light-directed or screen-directed indicators.
- Return: After picking, the tote is automatically returned to its storage location or repositioned based on updated demand algorithms.
Key Benefits of OSR Shuttle™ Technology
The OSR Shuttle™ system delivers transformative advantages for fulfillment operations:
- Exceptional throughput: Each shuttle vehicle operates independently, allowing the system to process hundreds of tote movements per hour per aisle. Multiple aisles working in parallel create massive cumulative throughput.
- Scalability: The modular design means additional shuttle vehicles, levels, or aisles can be added as volume grows — without disrupting ongoing operations.
- Energy efficiency: Lightweight shuttle vehicles with regenerative braking consume significantly less energy than traditional crane-based AS/RS systems.
- Intelligent sequencing: The system can sequence totes for delivery in the exact order needed for multi-item orders, reducing pick station complexity and boosting efficiency.
- High storage density: Multi-deep storage configurations maximize the use of vertical and horizontal space within the facility.
OSR Shuttle™ at the FulfillmentTR Bursa Facility
At our Bursa warehouse, the OSR Shuttle™ system forms the backbone of our e-commerce fulfillment operations. It manages thousands of unique SKUs across multiple product categories, serving brands on Trendyol, Hepsiburada, Amazon Turkey, and international marketplaces. The system enables us to guarantee same-day shipping for orders placed before the cutoff time and maintain our industry-leading 99.9% accuracy rate.
FourWay Shuttle: Heavy-Duty Pallet Automation
How the FourWay System Works
While the OSR Shuttle™ excels at handling totes and small-to-medium items, the FourWay shuttle system is engineered for pallet-level storage and retrieval. As the name suggests, the FourWay shuttle vehicle can travel in four directions — forward, backward, left, and right — within a deep-lane racking structure.
The FourWay system operates as follows:
- Pallet intake: Full pallets from inbound shipments are placed at the entry point of the racking system. The FourWay vehicle picks up the pallet and navigates through the rack structure.
- Deep-lane storage: The vehicle can travel deep into storage lanes, placing pallets in positions that maximize density. Because it moves in four directions, it can access any position within the 3D grid without requiring dedicated aisles for each lane.
- Retrieval: When pallets are needed — either for replenishment of the OSR Shuttle™ system, bulk orders, or outbound shipping — the FourWay vehicle retrieves the specified pallet and delivers it to the designated output point.
- Level changes: Vertical lifts transfer the FourWay vehicles and pallets between levels of the racking system, enabling full utilization of warehouse height.
Advantages of FourWay Pallet Automation
- Maximum space utilization: Deep-lane storage eliminates the need for aisles between every rack row, increasing storage capacity by up to 60% compared to conventional pallet racking.
- FIFO and LIFO flexibility: The four-directional movement allows the system to support both first-in-first-out and last-in-first-out inventory strategies based on product requirements.
- Reduced forklift dependency: Automated pallet handling minimizes the need for manual forklift operations, improving safety and reducing damage to goods and infrastructure.
- Seamless integration: The FourWay system integrates directly with the OSR Shuttle™ via automated replenishment workflows, ensuring the tote-based system is always stocked with the right products.
FourWay in Practice at FulfillmentTR
In our Bursa facility, the FourWay system manages bulk inventory storage for high-volume products. When the OSR Shuttle™ system detects that a particular SKU is running low in its tote inventory, an automated replenishment request triggers the FourWay system to retrieve the relevant pallet and deliver it to a decanting station. This seamless flow ensures zero stockout situations within the pick system and maintains uninterrupted order processing.
TwoWay Shuttle: Efficient Tote and Carton Handling
How the TwoWay System Works
The TwoWay shuttle system operates on a similar principle to the OSR Shuttle™ but is optimized for specific use cases involving tote and carton handling in scenarios where bidirectional movement is sufficient. The TwoWay vehicle moves forward and backward along a single rail within a storage aisle, accessing storage positions on both sides.
Key operational characteristics include:
- Single-aisle operation: Each TwoWay vehicle is dedicated to a specific aisle and level, providing focused throughput within its zone.
- Double-deep access: The vehicle can store and retrieve totes in double-deep positions, increasing storage density within each aisle.
- Vertical integration: Like the FourWay, lifts transfer totes between levels, creating a cohesive multi-level storage solution.
- Buffer functionality: TwoWay systems often serve as buffer storage for pre-picked orders, returns processing, or staging areas for outbound consolidation.
Benefits of TwoWay Technology
- Cost-effective automation: For operations that don’t require the full four-directional flexibility of the OSR Shuttle™, the TwoWay provides a more cost-efficient automation path with excellent performance.
- High reliability: Simpler mechanical design translates to fewer maintenance requirements and higher system uptime.
- Dedicated throughput: Each vehicle serves its assigned zone without contention, providing predictable and consistent performance.
- Ideal for buffer and sequencing: The TwoWay excels in applications where totes need to be stored temporarily and released in a specific sequence — critical for multi-order batch processing.
How These Systems Work Together: An Integrated Ecosystem
The true power of automated warehouse systems emerges when OSR Shuttle™, FourWay, and TwoWay technologies are deployed as an integrated ecosystem rather than isolated solutions. At FulfillmentTR’s Bursa facility, these systems work in concert:
- FourWay manages bulk pallet storage and feeds replenishment to the tote-based systems.
- OSR Shuttle™ handles the core goods-to-person picking operations, processing individual e-commerce orders with speed and precision.
- TwoWay provides buffer storage, order consolidation, and sequencing support, ensuring smooth outbound operations.
All three systems are orchestrated by a unified warehouse management system (WMS) and warehouse control system (WCS), which optimize workflows in real time. The WMS determines what needs to happen — which orders to process, which items to replenish — while the WCS manages how the physical systems execute those tasks, coordinating shuttle movements, lift operations, and conveyor flows.
Real-World Impact: Performance Metrics at FulfillmentTR
The integration of Knapp’s automated systems at our facility has delivered measurable results:

Choosing the Right Automated System for Your Needs
Not every warehouse operation requires all three systems. The optimal configuration depends on several factors:
- Order profile: High-volume, multi-SKU e-commerce operations benefit most from the OSR Shuttle™ for picking. Operations with large bulk movements benefit from FourWay pallet automation.
- SKU characteristics: Small, varied products are ideal for tote-based systems. Large, heavy, or palletized goods call for FourWay solutions.
- Throughput requirements: Facilities processing thousands of orders daily need the parallel processing power of the OSR Shuttle™. Lower-volume operations may find TwoWay systems provide the right balance of automation and investment.
- Growth trajectory: All three systems are modular and scalable, but planning for future capacity during initial design prevents costly retrofits later.
