Challenge

Managing Thousands of SKUs While Controlling Warehouse Labor Costs

With the rapid growth of e-commerce and customized manufacturing, many warehouses face increasing operational pressure:

1. High SKU Complexity

Traditional warehouse operations become inefficient when managing:
Thousands of product types
Frequent order changes
Small batch picking requirements

2. Low Manual Picking Efficiency

Traditional storage methods require operators to:
Walk long distances
Search manually for products
Spend significant time on picking operations

This creates bottlenecks during peak order periods.

3. Limited Warehouse Space

Expanding warehouse buildings increases:
Construction investment
Operating costs
Long-term management expenses

The customer needed a solution that could maximize existing warehouse space while improving fulfillment speed.

4. Increasing Labor Dependency

Labor shortages and rising operational costs make traditional warehouse models difficult to scale.

The company required an automated solution that could maintain stable performance with less manual involvement.

Solution

High-Density Mini Load ASRS with Goods-to-Person Picking Workflow

To solve these challenges, the project implemented a complete automated warehouse system based on mini load ASRS technology.

The solution includes:

1.Four-Aisle High-Speed Stacker Crane System

Four stacker cranes independently operate inside the storage aisles.

Each crane performs:
Automated storage
Automated retrieval
High precision positioning
Continuous operation

2.Automated Bin Storage

The warehouse uses standardized bins to maximize storage density.

The system provides:
Better space utilization
Faster inventory access
Accurate SKU tracking

3.Integrated Picking Workflow

The ASRS system connects directly with:

Conveyor systems
Sorting equipment
Picking stations

Creating a goods-to-person operation model.

4.Intelligent Warehouse Management

The automation system coordinates:

Inventory allocation
Storage location optimization
Order sequencing
Equipment scheduling

Workflow & Layout

Automated Warehouse Operation Process

The complete workflow includes:

1. Goods Receiving

Incoming products are scanned and registered into the warehouse management system.

2. Automated Storage

The system automatically assigns storage locations.
Stacker cranes transport bins into optimized storage positions.

3. Order Processing

Customer orders enter the warehouse control system.
The system calculates the optimal retrieval sequence.

4. Automated Retrieval

Stacker cranes quickly retrieve required bins.

5. Goods-to-Person Picking

Bins are automatically transported to picking stations.
Operators complete picking without walking inside storage aisles.

6. Sorting and Outbound

Products are sorted, packed, and transferred to shipping areas.

Results & ROI

  • Improving Warehouse Efficiency Through Automation
  • The implementation delivered several business improvements:
  • 1. Higher Storage Density
  • Vertical automated storage maximizes warehouse space utilization compared with traditional shelving systems.
  • 2. Faster Order Fulfillment
  • Goods-to-person picking eliminates unnecessary operator movement and improves picking efficiency.
  • 3. Reduced Labor Dependency
  • Automation reduces reliance on manual storage and retrieval operations.
  • 4. Improved Inventory Accuracy
  • Automated storage location management reduces:
  • Picking errors
  • Inventory discrepancies
  • Manual tracking requirements
  • 5. Better Scalability
  • The modular mini load ASRS design allows companies to expand automation capacity as business volume grows.

Project Overview / Opening

How Can Companies Handle Thousands of SKUs Without Expanding Warehouse Space?

For e-commerce, retail, and spare parts businesses, warehouse complexity grows faster than physical storage space.

More products mean:
More SKUs
More picking operations
More labor requirements
More management difficulty

This mini load ASRS project provides a solution by combining high-density automated storage with intelligent picking operations.

The goal was not simply to automate storage, but to create a faster, more scalable, and more efficient fulfillment system.

Key Points

  • Why This Mini Load ASRS Solution Stands Out?
  • 1-High SKU Capability
  • Designed for warehouses handling:
  • Thousands of SKUs
  • High order frequency
  • Small-item storage requirements
  • 2-Four-Aisle Independent Operation
  • Multiple stacker cranes work simultaneously to improve throughput and operational flexibility.
  • 3-Goods-to-Person Efficiency
  • Employees focus on picking instead of searching and walking.
  • 4-Space Optimization
  • Vertical storage design increases warehouse utilization.
  • 5-Scalable Automation Architecture
  • The system can support future business growth.
