No one can afford to lose track of valuable assets. That’s why we’ve seen radio frequency identification (RFID) and Bluetooth®-enabled tracking devices become extremely popular in both the consumer and commercial sectors these last few years. Tagging everything from phones and wallets to pallets and vehicles can help owners quickly recover missing items, whether misplaced or stolen. But tracking an item’s movements is far more than just a security tactic. It’s a strategic imperative, especially in automotive manufacturing environments.
Using a real-time indoor location system to track and trace physical assets is one of the best – if not only – ways to see with near-perfect accuracy where equipment or inventory is located, how it got there, and where it may be better stored or utilized. It’s the key to unlocking greater workflow efficiency and improving overall operational performance when order volume is high and output capacity is constrained. This type of technology, if applied properly, is also indispensable in anticipating the implications of certain decisions and actions so corrections can be made in real time as needed.
For example, automakers who are trying to compensate for lost time and revenue stemming from pandemic production shutdowns and current chip shortages are exploring high-impact ways to allay further losses.
In a perfect world, they would be able to ramp production to meet demand for more upgraded and personalized vehicles. Current inventory levels and production lags are forcing consumers to either settle with what’s on the lot or wait to see what comes available in a few months. Neither scenario is ideal for the automotive industry as upgrades and customization drive greater margins. Plus, people eager to buy now might not still be in the market for a new vehicle in a few months. They may opt for a resale or decide they don’t need to spend money on such a purchase after all. Yet, there are a lot of factors influencing production capacity right now, including labor and chip shortages – which aren’t within automakers’ control.
What they can control, however, is production speed and quality along with operational efficiency – all of which impact margins. For example, we’re seeing many manufacturers turn their attention back to the circular economy model and embrace technologies that make it easy to track – and salvage – reusable containers. Some are also leveraging real-time location systems (RTLS) as a foundational element for smart factories. The COVID-19 pandemic uncovered vulnerabilities in traditional just-in-time production and delivery methods, driving manufacturers to rethink the ways in which they can mitigate the impact parts shortages may have on output and their bottom lines. What did you uncover in your operations? Were there areas you didn't realize you were taking losses? How many of those losses could have been detected and mitigated had you been using RFID or other location technology to track, trace and recover items?
It’s a tale as old as time: an automotive parts supplier packs up a container, ships it off to the manufacturing plant, and then hopes it will be returned once unpacked so it can be reused again. In many cases, it’s not – at least not automatically. So, the supplier calls the manufacturer to track it down. But the manufacturer has a wall – or warehouse – of empty containers and no way to easily discern which ones belong to which suppliers because containers are tracked using only paper forms and manually-scanned barcodes.
What happens next is a toss-up. Containers could be misdirected to other suppliers, held for a prolonged period by the manufacturer, or reused by the manufacturer (or another supplier). This leaves the original supplier/container owner with two choices:
Both of these options waste money, labor resources and time. So does the manual management of any asset, including something as seemingly mundane as shipping containers.
To be fair, the use of reusable containers in and of itself drives complexity into the supply chain as it involves forward distribution and reverse logistics. However, most – if not all – of that complexity can be eliminated by using RFID tags, readers and cloud-based monitoring tools to automatically track and locate the containers as they move between the different manufacturing and assembly sites. The same visibility instrumentation could even be used to track each container’s contents if desired. Talk about doubling your return on investment (ROI)!
Once the supplier can see where a container is located, it becomes so quick and easy to:
Containers and components aren’t the only things susceptible to loss in a fast-paced factory environment. Finished products can be misplaced too, including industrial trucks. I know…you’re probably wondering how that’s possible. But it’s important to remember that automotive production facilities are gigantic, and several things can interfere in the vehicle transport process – even within the four walls. Automakers need to be able to confirm that a truck made it from Point A to Point Z on time and without issue, before a distributor or customer calls to inquire about a delay. They also need to be able to see workflow hazards that could result in damage to the newly-minted truck. For example, is the truck being driven across a high-traffic area and unnecessarily exposed to things that could ding it along the way? Or is it being improperly staged by the loading dock, leading to bottlenecks in the entire loading process?
Similarly, the movement of material handling vehicles – or lack thereof – can either make or break a manufacturers’ ability to meet production and shipping deadlines. If a forklift is routed the long (or wrong) way across a facility, subsequent processes that rely on that material will be impacted. Or if there is something that repeatedly causes an obstruction in the traffic flow, an entire workflow can become stagnant. But it’s not easy to recognize, much less assess, those patterns without the type of visualization provided by indoor location technologies. There’s something about seeing a cluster of red dots (i.e., tagged assets) sitting in a holding pattern on a computer screen that makes it easier to identify issues and pinpoint why they are happening. Perhaps it’s the ability to track and trace each asset individually, see all the moving parts from an “overhead” view, or replay the scenario from different angles. Regardless, the ability to sense, analyze and act when issues arise has become invaluable to auto manufacturers that value every asset, not just those sold on the open market. It’s also the key to sustaining a just-in-time production model, even when external pressures challenge one’s ability to keep pace with demand,
There are several benefits to be gained from RTLS, particularly indoor location technologies. The most remarkable, at least in today’s climate, are loss avoidance and optimized asset utilization. Though the chip shortage is pretty much over, there is still a need for manufacturers and suppliers to reduce, reuse, recycle - from sustainability targets to cost control measures.
I encourage you to call a Zebra representative or partner to learn more about how much you can gain from the real-time visibility and business intelligence delivered via technologies such as RFID, Ultra Wideband RTLS, and Bluetooth Low Energy beacons.
