How to Design a High-Throughput ASRS Warehouse with ACR and AMR Robots

Designing a high-throughput automated warehouse is not simply about adding more robots.

A true high-performance ASRS system requires careful coordination between warehouse layout design, robot role separation, zoning strategy, and throughput modeling.

This guide explains how to design a scalable ASRS warehouse using ACR (Autonomous Case/Rack Robots) and AMR (Autonomous Mobile Robots) to achieve high efficiency, flexible expansion, and stable throughput performance.

Most warehouse automation projects fail not because of robot performance—but because of poor system design.

Common design problems include:

Unbalanced warehouse layout
Incorrect robot role allocation
Poor storage density planning
Bottlenecks in picking zones
Lack of throughput modeling
Limited scalability planning

Without proper design, even advanced ASRS systems cannot reach their full performance potential.

A high-performance ASRS warehouse must be designed as a multi-layer intelligent system, not just a collection of machines.

The optimal design approach includes:

Clear separation of ACR and AMR responsibilities
Zoning-based warehouse structure
Throughput-driven layout planning
Simulation-based capacity validation
Modular expansion capability

This ensures both high efficiency and long-term scalability.

A standard high-throughput ASRS warehouse layout includes four main zones:

Step 1: Receiving Zone
Inbound goods are received, scanned, and registered into WMS.
Key functions:
SKU identification
Barcode scanning
Quality check
System registration

Step 2: AMR Transport Zone
AMR robots handle horizontal movement between functional areas.
Key roles:
Transport inbound goods to storage zone
Move goods to picking or buffer zones
Reduce manual forklift dependency

Step 3: ACR Storage Zone
ACR robots manage vertical storage and retrieval inside high-density racks.
Key roles:
Automated bin storage
Deep-rack retrieval
Dynamic slot allocation
High-density storage optimization

Step 4: Picking & Buffer Zone
This is the high-frequency operation area.
Functions include:
Order picking
Product consolidation
Sorting and staging
Order preparation for outbound

Step 5: Outbound Zone
Final shipment processing:
Packing
Labeling
Dispatch coordination

High-throughput warehouse performance depends heavily on system design architecture.

While many companies focus on robot quantity, the real performance driver is how well the system is structured.

A well-designed ASRS warehouse ensures:

Stable throughput
Efficient robot coordination
Scalable expansion capability
Minimal bottlenecks

• 1️⃣ ACR vs AMR Role Separation
• ACR (Storage Layer)
• Vertical storage operations
• High-density rack handling
• Bin retrieval and placement
• AMR (Transport Layer)
• Horizontal movement
• Zone-to-zone transfer
• Buffer and staging operations
• Clear separation avoids operational conflict and improves system efficiency.
• 2️⃣ Multi-Zone Warehouse Design
• A high-performance warehouse is divided into:
• Receiving zone
• Storage zone
• Picking zone
• Buffer zone
• Outbound zone
• Each zone operates independently but is synchronized through WMS/WCS.
• 3️⃣ Throughput Design (Bins/Hour Model)
• Throughput is calculated based on:
• Robot speed
• Travel distance
• Storage density
• Task allocation efficiency
• Example:
• Small system: 100–200 bins/hour
• Medium system: 200–400 bins/hour
• High-throughput system: 400–600+ bins/hour
• 4️⃣ Bottleneck Prevention Strategy
• Common bottlenecks:
• Picking zone congestion
• AMR transport delays
• Storage retrieval conflicts
• Solution:
• Parallel zone design
• Dynamic task scheduling
• Buffer zone integration
• 5️⃣ Scalability Planning
• A scalable ASRS design must support:
• Additional ACR robots
• Additional AMR fleet expansion
• Rack system expansion
• Software upgrade capability
• Recommended design principle:
• Plan for +30% future capacity expansion from day one.

Designing a high-throughput ASRS warehouse is fundamentally a system engineering challenge, not just an equipment selection process.

The key to success lies in:

✓ Proper ACR vs AMR role separation
✓ Multi-zone architecture design
✓ Throughput-driven planning
✓ Bottleneck elimination strategy
✓ Scalability-first thinking
