Buffer Sequencer by SAVOYE North America
In high-performance automated fulfillment, shuttle systems are often the heartbeat of the operation—but without proper flow management, they can become the bottleneck. Many facilities unknowingly pay for underutilized automation because orders arrive in the wrong sequence, feeding the system inefficiently.
The SAVOYE Buffer Sequencer eliminates that problem. Purpose-built to complement our X-PTS® shuttle systems, it balances inbound and outbound flows, organizes items into the correct sequence, and ensures shuttles operate at optimal capacity, all day, every day.
What Is the SAVOYE Buffer Sequencer?
The Buffer Sequencer is an intelligent pre-staging and flow-balancing module that temporarily stores, orders, and releases totes or cartons in the exact sequence required for downstream operations.
Integrated directly with AiRVOS™ WES and X-PTS® shuttles, it acts as the “traffic controller” for your automated system, smoothing peaks, preventing stoppages, and ensuring product arrives at picking or packing stations in the right order.
It is ideal for:
• Goods-to-Person (GTP) picking
• High-throughput order consolidation
• Packaging lines requiring item or SKU sequencing
• Mixed-SKU carton preparation
• High SKU-variety environments
Why Sequencing Matters
Without proper sequencing, shuttles waste cycles retrieving totes only to wait for earlier SKUs—or worse, stopping entirely.
This leads to:
• Low shuttle utilization
• Unnecessary storage movements
• Lower throughput at the workstation
• Higher cost per order
The Buffer Sequencer eliminates these inefficiencies by organizing items before they enter the shuttle flow.
Key Benefits & Advantages
Maximum Shuttle Utilization
The Buffer Sequencer ensures a constant, properly ordered flow of totes, allowing your X-PTS® shuttles to work at peak efficiency.
Result: higher throughput with fewer shuttles—even during peak periods.
Prevents Over-Investing in Automation
Many facilities oversize their shuttle system to compensate for poor sequencing.
The Buffer Sequencer avoids this by optimizing flow, which means:
• Fewer shuttles required
• Lower CAPEX
• Faster ROI
Eliminates Bottlenecks at GTP Stations
Operators receive totes in the exact order needed—no waiting, no rework, no pauses.
This improves:
• Pick station continuity
• Lines per hour
• Labor efficiency
Smooths Peak and Batch Variability
When order profiles shift or SKU demand spikes, the sequencer absorbs the imbalance and feeds the system at a steady pace.
This avoids stoppages and maintains consistent system performance.
Enhances 1-to-1 and Multi-Order GTP Performance
Whether you operate 1:1 stations or multi-order setups, the Buffer Sequencer creates the right order logic, improving:
• Pick accuracy
• Ergonomic pacing
• Operator experience
Seamless Integration With AiRVOS™ WES
AiRVOS™ manages the logic, ensuring:
• Real-time flow orchestration
• Predictive release of totes
• Intelligent buffering
• System-wide optimization
Together, AiRVOS + X-PTS + Buffer Sequencer provide a vertically integrated flow engine.
How It Works
- Inbound totes arrive from storage or receiving.
- AiRVOS™ determines the required sequence based on order, station, and SKU logic.
- The Buffer Sequencer temporarily stores and organizes totes in dynamic lanes.
- When the system is ready, totes are released in the optimal order to:
- Shuttle lifts
- GTP workstations
- Sortation or consolidation zones
Where the Buffer Sequencer Creates the Most Value
This technology is especially impactful in:
- E-commerce & omnichannel fulfillment
- Office supplies distribution (high SKU variety)
- Retail replenishment (store-friendly sequencing)
- Pharma & health products (batch and lot-sensitive flows)
- Industrial parts & MRO (heavy SKU complexity)
If your operation has unpredictable order profiles or frequent SKU mixing, this module delivers immediate efficiency gains.
A Perfect Match for the X-PTS® Shuttle System
The X-PTS® shuttle system excels at high-density storage and fast retrieval.
The Buffer Sequencer ensures those retrievals happen in the right order and at the right pace.
Together, they deliver:
- Higher storage performance
- Faster workstation throughput
- Lower cost per order
- Better utilization of hardware and labor
Why SAVOYE North America’s Buffer Sequencer Is Different
- Developed by an OEM engineering both software and hardware
- Seamless integration with AiRVOS™ WES
- Designed specifically to maximize X-PTS® shuttle performance
- Modular configurations to match your throughput and footprint
- Able to integrate with third-party automation as needed
This isn’t an add-on—it’s a strategic flow optimizer built into our system philosophy.
Unlock Higher Throughput With Less Hardware
If you want your shuttle system to hit its performance targets without oversizing your automation, the SAVOYE Buffer Sequencer is one of the most impactful modules you can deploy.
