Technology
- Project Background
- Challenges of High SKU Warehouse Operations
- With the rapid growth of e-commerce and retail industries
- warehouses are required to manage thousands of SKUs while maintaining fast order fulfillment speed.
- Traditional warehouse operations often face several challenges:
- Limited Storage Capacity
- Conventional shelving systems require large operation aisles and cannot fully utilize vertical warehouse space.
- As SKU numbers increase
- companies need more warehouse area to maintain inventory.
- Slow Picking Efficiency
- In traditional warehouses
- operators need to manually travel between storage locations to find products.
- This person-to-goods picking method increases:
- Walking distance
- Order processing time
- Human workload
- High Labor Dependency
- Large-scale manual warehouse operations require many employees for:
- Storage handling
- Product searching
- Picking activities
- Inventory checking
- Increasing labor costs make traditional warehouse models difficult to scale.
- Complex Inventory Management
- High SKU warehouses require accurate inventory tracking and fast response to changing customer demands.
- Manual management often creates:
- Inventory errors
- Low visibility
- Inefficient replenishment
Challenge
Project Requirements
Automated Warehouse Requirements
The customer required an intelligent warehouse solution capable of handling a large number of SKUs with high-frequency order picking requirements.
The main requirements included:
High-density storage capability
Fast automatic storage and retrieval
Reduced manual operation
Accurate inventory management
Continuous connection between storage and picking processes
The final solution needed to combine storage efficiency with fast order fulfillment performance.
Solution
4-Aisle Mini Load ASRS Architecture
The project adopts a multi-aisle Mini Load ASRS system consisting of four independent storage aisles.
Each aisle is equipped with a high-speed stacker crane responsible for automatic bin storage and retrieval.
The four stacker cranes operate independently while being coordinated through the warehouse control system.
The complete workflow includes:
Warehouse receiving
↓
Automated bin identification
↓
Automatic storage by stacker crane
↓
Order processing through WMS/WES
↓
Automatic retrieval
↓
Goods-to-person picking
↓
Sorting and outbound delivery
Workflow & Layout
From Receiving to Shipping
Step 1: Receiving Process
Incoming products are registered into the warehouse management system.
The system assigns appropriate storage locations according to product information.
Step 2: Automated Storage
Bins are transported automatically to assigned locations.
Stacker cranes complete storage operations with high positioning accuracy.
Step 3: Order Management
Customer orders are received by the warehouse management system.
The system analyzes:
Product information
Storage location
Picking priority
Step 4: Automatic Retrieval
The Mini Load ASRS automatically retrieves required bins.
Multiple aisles can operate simultaneously to improve throughput.
Step 5: Goods-to-Person Picking
The required products are delivered to operators through automated transportation systems.
Operators complete picking without walking through storage aisles.
Step 6: Sorting and Shipping
After picking, products enter sorting and outbound processes.
The complete workflow improves order fulfillment speed and accuracy.
