Bin-Type AS/RS vs. Traditional Shelving: A Deep Dive on Storage Density & Throughput

In today's rapidly evolving e-commerce and warehouse environment, maximizing storage density and throughput efficiency is more critical than ever. A Bin-Type Advanced Storage and Retrieval System (AS/RS) offers unparalleled advantages compared to traditional shelving systems when it comes to these two key performance indicators. Everunion's innovative Bin-Type AS/RS systems offer high-speed automated storage and retrieval solutions, making them the perfect choice for small item warehouse systems, e-commerce fulfillment automation, tote storage and retrieval, and pharmaceutical automated storage. This article delves into a deep analysis of storage density and throughput, presenting a comprehensive comparison between Bin-Type AS/RS and traditional shelving systems.

Core Components and Operations

Bin-Type AS/RS Overview

A Bin-Type AS/RS system utilizes robots to retrieve and retrieve bins from an aluminum grid, ensuring high-speed storage and retrieval operations. The system consists of a few key components:

• Bins: Inventory is stored in bins, which are stacked like building blocks within an aluminum grid.
• Aluminum Grid: The grid provides a secure and stable structure for storing bins.
• Robots: Robots travel on tracks along the top of the grid, retrieving and delivering bins to ports (warehouse workstations) as directed by the system.
• Ports: Workers can access inventory for order fulfillment or restocking at the ports. Robotic efficiency ensures bins are quickly returned to the grid after use.

The advanced algorithms used in systems like AutoStore ensure that high-demand items are prioritized at the top, while bins are continuously delivered to ports. This process not only ensures fast and efficient operations but also minimizes the time required for inventory retrieval.

Traditional Shelving Overview

Traditional shelving systems involve racks and aisles for storage and retrieval of inventory:

• Racks: Large racks equipped with shelves for storing goods.
• Aisles: Wide aisles to accommodate manual retrieval of goods.
• Manual Labor: Workers walk down aisles to retrieve and return inventory manually.

While traditional shelving systems are simple and can be understood easily, they face several limitations compared to Bin-Type AS/RS systems, especially in densely packed warehouses. Traditional shelving systems require significant aisle space, making them less space-efficient than Bin-Type AS/RS systems.

Storage Density Comparison

Maximizing Space Utilization

Storage density refers to the amount of inventory that can be stored in a given space. Bin-Type AS/RS systems excel in this area due to their compact design and efficient use of vertical and horizontal spaces.

Bin-Type AS/RS Metrics

• High-Density Storage: Bins are stacked in a grid-like structure, utilizing nearly 100% of vertical and horizontal space.
• Reduced Aisle Space: The absence of wide aisles required for manual retrieval increases overall storage density.
• Flexibility: Customizable grid sizes allow for optimal space utilization based on specific warehouse requirements.

Traditional Shelving Metrics

• Inefficient Vertical Space: Tall racks may be utilized, but the presence of wide aisles reduces overall storage capacity.
• Fixed Layout: Limited ability to adjust layout for optimal density.
• Occupied Space: Significant portion of space is occupied by aisles and manual retrieval areas.

Throughput Analysis

High-Speed Retrieval Operations

Throughput refers to the rate at which inventory can be stored and retrieved. Bin-Type AS/RS systems offer superior throughput efficiency compared to traditional shelving systems.

Bin-Type AS/RS Metrics

• Robotic Efficiency: High-speed robots retrieve and deliver bins in seconds.
• 24/7 Operation: Capable of running continuously without manual intervention.
• Self-Learning Algorithms: Advanced algorithms prioritize high-demand items, further boosting efficiency.

Traditional Shelving Metrics

• Manual Retrieval Time: Manual workers take time to retrieve and return items, which can lead to delays.
• Labor Intensive: Significant manual labor is required for retrieval and restocking.
• Variable throughputs: Human factors can impact the number of items processed per hour

Cost Overview

Initial Setup Costs

Initial setup costs for automated storage systems can vary based on the size and complexity of the project:

• Bin-Type AS/RS Systems: Relatively higher initial cost due to advanced robotics and digital controls.
