The Benefit of Automated Storage/Retrieval Systems (AS/RS) in Manufacturing

With 30+ years working with the largest OEM automakers and suppliers, GE Vernova has developed many manufacturing solutions, deployed at thousands of sites around the world.

Often these solutions have value that extends far beyond automotive manufacturing. An example of an application that we’ve deployed with customers is bank management automation – consisting of various configurations such as multiple lane banks and an Automated Storage/Retrieval System (AS/RS). This type of solution benefits automotive manufacturers but also any manufacturer with improved storage capacity and throughput needs.

What is an AS/RS?

An AS/RS system is typically an arrangement of two banks of storage cells with a crane/lift separating the banks. The system allows for incoming items to be put into any available storage cell, and based on demand, any item can be retrieved directly.

AS/RS can consist of multiple banks and cranes based on storage and throughput requirements. The storage banks make use of vertical space within a manufacturing facility in order to decrease horizontal space requirements.

Think of a storage bank as a mini warehouse, buffering areas of production so that disruptions in one part of production do not immediately affect other areas. Additionally, the buffers can be used for resequencing material flow to optimize various production areas.

There is a storage area and a system in order to store and retrieve the items – designed for speed and efficiency. In the automotive examples where vehicle bodies are stored/retrieved, crane systems are used. However, AS/RS systems can provide value in many different types of manufacturing.

Advantages of automated storage and retrieval systems

Some of the benefits of implementing an AS/RS system include:

In the automotive industry, vehicle bodies are stored in the mixed bank after they have been painted and prior to making their way into the final assembly process. The mixed bank helps manufacturers set the sequence of vehicles moving into final assembly based on rules. For example, there may be a rule to limit the number of vehicles with a sunroof in order to maintain TAKT time. By using an AS/RS, material can be optimized for production.

GE Vernova's Proficy software interfaces with AS/RS hardware in order to control the decision making of the overall system.

At a recent implementation for a major automotive OEM, our AS/RS application uses CIMPLICITY HMI/SCADA to monitor and visualize real-time status and Tracker, which delivers routing and control to manage the inbound and outbound routing. Inbound bodies are stored to optimize outbound crane utilization. Outbound bodies are selected based on a set of configurable business rules.

GE Vernova's Professional Services

For some additional information on this customer’s application, I spoke to Don Walker who is a Senior Project Manager with our Professional Services team. Like myself, Don has spent a lot of time in automotive facilities over the years. He has managed many projects within our automotive customers and was heavily involved in the most recent AS/RS rollout we did.

Question: What value did the AS/RS system give to the customer?

Don Walker: The advantage that this new system has over the customer’s old system is that operators can see exactly where items are out on the floor. This information combined with alarm and status messages allow them to troubleshoot issues quickly and easily. And all screens are available on mobile devices, so users can access the system from anywhere.

With the logic built into the system, most of the time it is running on its own. Sometimes though things can go wrong in which case the Manual Control gives them the ability to fix issues.

Question: We’ve been working with automotive customers for a long time. What benefit does that experience give to customers?

Don Walker: Leveraging what we’ve done with other automotive customers, we were able to put this system together quickly, providing significant implementation cost savings.

Question: Anything else you’d like to add?

Don Walker: The customer loves the support they get from our team.

If you’re a manufacturer, AS/RS can help you improve capacity in your facility with a more compact footprint, decrease errors in selecting materials, increase throughput with greater efficiency, and provide higher availability with a manufacturing buffer.

GE Vernova has both the proven Proficy software and expert Professional Services to deliver fast time to value with an AS/RS solution. Find out today how our team can improve your manufacturing efficiency.
