DCs apply sensors, wireless networks, and the Internet of Things to the warehouse yard, a traditionally low-tech node in the supply chain that’s getting new attention in a time of heightened operating restrictions.
Ben Ames has spent 20 years as a journalist since starting out as a daily newspaper reporter in Pennsylvania in 1995. From 1999 forward, he has focused on business and technology reporting for a number of trade journals, beginning when he joined Design News and Modern Materials Handling magazines. Ames is author of the trail guide "Hiking Massachusetts" and is a graduate of the Columbia School of Journalism.
As the logistics industry adjusts to a new world marked by tight caps on drivers’ hours of service amid pandemic-fueled demand surges and operating restrictions, many companies are turning to technology that can help them cope with these challenges, leading to the rise of the “digital yard.”
With the hours-of-service (HOS) mandate restricting drivers’ road time, companies are looking for ways to boost efficiency in other parts of the supply chain, says Chris Wolfe, CEO of asset management solution provider PowerFleet Inc. With driving time at a premium, many businesses see the yard as a “chokepoint” where drivers can waste many of their allotted hours waiting in line for a DC dock door to open up, he adds.
But it doesn’t have to be that way, Wolfe says. DCs can gather data from the trucks in their yards by tapping into the sensors increasingly found on everything from truck cabs to trailers to drivers’ own smartphones as well as the increasingly sophisticated Internet of Things (IoT) networks that allow facilities to identify and track nearly every asset that rolls onto their property. They can then mine these rich veins of data to fine-tune dock and yard operations to avoid backups and delays.
DCs LOOK TO THE YARD TO CUT WASTE
The rise of the digital yard is accelerating as trading partners seek more-efficient operations. “This is the evolution of where things have to go based on … HOS. That’s where the next savings is in asset utilization,” Wolfe says.
In the new model of yard operations, companies can combine local sensor data with yard management system (YMS) and transportation management system (TMS) software platforms to squeeze inefficient practices out of the process—the kinds of practices that have led to the long lines of trucks waiting to load or unload that have become common in the coronavirus era. Instead, sensors monitoring variables like weight and motion can detect when a truck is ready to leave the DC and instantly alert warehouse managers.
Among other benefits, those precise metrics enable facilities to avoid backups by notifying suppliers to delay shipments or by warning incoming drivers that a dock door won’t be ready for a scheduled delivery. While the delay could still count against the drivers’ service hours, the advance notice might allow them to wait it out at a truck stop with amenities instead of sitting in a line of trucks outside a warehouse.
“How fast is a trailer getting loaded? If you find it’s not even half loaded, then you may as well slow a driver down and have him wait somewhere else. The worst thing you can do right now is have drivers waiting” in the yard, where they may be unable to maintain the recommended social distances, Wolfe says. “But if a driver knew when to arrive, he wouldn’t have to wait. Everything has to work like a well-oiled machine.”
That machine can be oiled by the vast streams of data that can be collected from a digital dock and yard management system, says Tim Kubly, business development manager for Rite-Hite Digital Solutions. “Customers want to know what’s happening with their equipment without standing there and looking at it the whole time. Now, with the Industrial Internet of Things, we can collect data and push it out to an intuitive dashboard,” Kubly said in a recent webinar, pointing to his firm’s Opti-Vu and Dok-Vu dashboards as examples.
“That means we can monitor detention time. A company might want to make sure it gets trailers off the dock within two hours. But the problem is that workers may not know how long a trailer has been there,” Kubly said. “Now, when a trailer backs up to the dock and the trailer lock is engaged, a timer starts.”
Depending on the type of dock equipment, the system could track sensor signals that detail every step in the inbound and outbound freight process. For example, Rite-Hite’s platform can track variables like trailer presence, door open, leveler down, forklift activity in trailer, leveler up, door closed, and trailer departure. DC managers can use those statistics to schedule the activities of drivers, warehouse workers, shipping and receiving staff, and yard jockeys, he said.
Another factor driving demand for digitized operations is the push for touchless operations during the Covid-19 pandemic, according to dock and yard management solution provider C3 Solutions. The company says its software products can reduce or eliminate paper transactions by using electronic documents instead of paper records on carrier/supplier web portals and for gate processes.
Yard management technology developer Pinc Solutions is taking a similar tack. Pinc says its Digital Yard solution is designed to automate gate activities, trailer movements, dock scheduling, yard operations, and more. The company’s Pinc Kiosk even supports a touchscreen multilanguage interface with a temporary radio-frequency identification (RFID)-tag dispenser that allows drivers to perform self-check-in and self-check-out.
YARD DATA FILLS IN VISIBILITY GAP
Supply chain visibility provider FourKites likewise had digital yard operations in mind when it announced in March that it had acquired three yard solution software platforms—Yard Management, Dock Management, and Gate Control—from TrackX Holdings Inc. All three of the newly acquired platforms collect data by building connections with enterprise resource planning (ERP) and warehouse management system (WMS) software as well as with RFID and IoT sensors. By tapping into that data flow, FourKites says it can now extend real-time freight visibility into the warehouse yard.
“I think we’ve really nailed where freight is during transit, but that is only one piece of the puzzle,” FourKites Founder and CEO Matt Elenjickal says. “Goods are being held in the yard for some time, whether it’s at pickup or dropoff. What people really want to know is, ‘Where are my products?’—regardless of whether they’re in transit, in the yard, or in the warehouse.”
But achieving that kind of universal traceability may not be so easy. FourKites acknowledges that some trading partners like third-party logistics service providers (3PLs), suppliers, and retailers have been hesitant to share shipping data with each other, although he says that’s starting to change. “We have a lot of customers who ship to retailers or who manufacture consumer packaged goods. We facilitate the sharing of data, but some people weren’t buying in because of data privacy concerns,” Elenjickal says. “One manufacturer said, ‘We’d be happy to share our data if you can mask our purchase orders and carrier lanes.’ And we said ‘OK, we can do that!’ The industry wants to collaborate more.”
Given the current pressure to deliver swift, smooth performance amid tightening restrictions, Elenjickal and others believe warehouse operators have a lot to gain from opening up access to their supply chain data. And one of the payoffs could be a big jump in efficiency at the dock and yard interface, where freight moves from truck to DC and back again.
Robotic technology has been sweeping through warehouses nationwide as companies seek to automate repetitive tasks in a bid to speed operations and free up human labor for other activities. Many of those implementations have been focused on picking tasks, a trend driven largely by the need to fill accelerating e-commerce orders. But as the robotic-picking market matures and e-commerce growth levels off, the robotic revolution is shifting behind the picking lines, with many companies investing in pallet-handling robots as a way to keep efficiency gains coming.
“Earlier in this decade and the previous decade, we [saw] a lot of [material handling] transformation around e-commerce and the handling of goods to order,” explains Josh Kivenko, chief marketing officer and senior vice president at Vecna Robotics, which provides autonomous mobile robots (AMRs) for pallet handling and logistics operations. “Now we’re talking about pallets—moving material in bulk behind that line.”
Kivenko explains that whether items are being packaged and shipped directly to a customer’s home address or moved as finished goods to a shipping bay for store delivery, those items are first moved in bulk in some way, often by human hands and with human-operated equipment. He describes warehouses as chaotic environments in which humans move pallets and cartons in multiple ways—up and down, side to side, from receiving to storage, from storage to shipping, or via cross-docking. Automation can help bring order to that chaos.
“What we’re trying to do is relieve some of the pressure [on the] humans [doing] this work,” Kivenko says of companies that develop pallet-handling robotic technologies. “At the end of the day, we’re trying to automate some of those flows, relieve labor pressure, save costs, and keep the goods flowing.”
But automated pallet handling isn’t right for every situation, so it’s important to understand the warehouse conditions required and the protocols and best practices needed to make it a win. Here are some guidelines for applying pallet-handling robots and gaining the most from your investment.
FIRST, UNDERSTAND THE TECHNOLOGY
Pallet-handling robots fall into four general categories, explains Rich O’Connor, vice president of storage and automation for Raymond West Group, a business unit of lift truck manufacturer The Raymond Corp. They include:
Palletizing/depalletizing robots, which are used to load or unload items onto and off of pallets, usually with the use of a robotic arm for picking and placing. Today, these systems are being increasingly integrated with automated storage and retrieval systems (AS/RS) to further streamline pallet handling in the warehouse, O’Connor explains.
Autonomous guided vehicles (AGVs) and autonomous mobile robots (AMRs), which are used to transport pallets within the warehouse. Often outfitted with lift decks or conveyors, or designed to tug or tow items, these robots move pallets from point A to B within a facility. AGVs, which often follow a marked guide-path or wire in the floor, have been around for many years, but the advent of high-performance guidance and vision systems is allowing them more flexibility today, O’Connor says. AMRs are self-guided vehicles that use software and sensors to navigate their way through the warehouse.
Forklift AGVs and AMRs, which can move products both horizontally, from place to place, and vertically, into and out of storage racks. They come in various styles—including stackers, counterbalanced trucks, reach trucks, and even very narrow aisle (VNA) vehicles for use in densely packed warehouses. These vehicles are more complex than those used only for horizontal transport, O’Connor explains. They must be “highly integrated” into the facility’s warehouse management system (WMS) or warehouse execution system (WES) so that they know precisely where to retrieve and deliver pallets within the facility.
Robotic pallet shuttles, which move pallets into, out of, and within dense storage racking. The Raymond Corp. describes such a system as “a standalone, automated deep-lane pallet storage system that utilizes self-powered shuttle carriages to move pallets toward the back or front in a racking channel. Shuttles are motor driven and travel along rails within a storage lane.”
O’Connor and others say that no matter which of these technologies you’re investing in, it’s important to remember that they are all part of a larger system designed to optimize operations throughout the warehouse.
“The expanding role of all these different styles working together is what’s amazing today,” O’Connor says.
SECOND, ENSURE THE TECHNOLOGY IS A FIT
Kivenko, of Vecna, also emphasizes the importance of pallet-handling robots working in concert, particularly AMRs and AGVs.
“The magic isn’t just that the robots are autonomous and driving by themselves. The magic is multiple robots—when you have a [whole integrated] system [in place],” he says. “[It’s] how the fleet operates autonomously and optimizes itself for continuous improvement. That’s where the exponential gains are. [It’s] not just about automating what a worker does; it’s about automating a system.”
But you can’t install these systems in just any warehouse and expect magic. Kivenko and others point to certain conditions that enable the best robotic pallet-handling outcomes, especially when it comes to transportation-based and forklift-type AMRs and AGVs.
“The robots that I sell are large-load machines with very expensive technology,” Kivenko explains. “They move material, generally, in larger facilities. And in order for them to produce a return [on investment]—because that’s the name of the game here—they have to be higher-velocity facilities.”
He says pallet-handling robots work best in large facilities running multiple shifts, usually more than five days a week. Wider aisles allow the equipment to move more freely through the facility and at higher speeds, to optimize efficiency and productivity. Strong Wi-Fi networks and clean, dry environments also help keep equipment running at top performance.
O’Connor agrees that pallet-handling robots are best suited to facilities with multishift operations, where they can ease labor constraints and boost productivity. And he says many customers are willing to extend the typical two- to three-year ROI period to five years in order to achieve those gains. But there is even more to it than that. O’Connor’s colleague John Rosenberger says customers must first step back and analyze their processes to ensure that, even if they have the right facility for pallet-handling AMRs or AGVs, they are moving material in the most efficient way to begin with.
“Many times, we find that the processes in place [are inefficient],” says Rosenberger, who is director of iWarehouse Gateway and global telematics for The Raymond Corp. He emphasizes the importance of analyzing existing data—from an equipment telematics system or similar—to determine the best path toward automation.
“Do you have congestion zones now?” he asks. “They’ll still exist if you automate [those processes exactly].”
THIRD, MAKE SIMPLICITY A PRIORITY
Another basic rule of thumb when implementing pallet-handling robotics: Keep it simple.
Andy Lockhart, director of strategic engagement for global warehouse and logistics process automation company Vanderlande, says that when designing a pallet-handling robotics system, “you want to minimize the processes you [automate]. When you can create [an automated system] that focuses on one task—for example, AMRs delivering pallets from a high-bay [storage rack] directly to the palletizing cell—you can do that efficiently and effectively. When you ask the AMR to do this and this and this … you are adding risk of failure.”
Lockhart’s colleague Jake Heldenberg advises customers to first test their target processes via pilot programs within the warehouse or DC. Heldenberg is Vanderlande’s head of solution design, warehousing, North America.
“If AGVs or AMRs for pallet handling are interesting [to a customer], the best thing to do is pilot one or two in an existing DC,” he says, explaining that the process can help companies troubleshoot, understand integration timelines, and gauge ROI. But pilot programs can add expense to a project, making it unaffordable for some.
“If that’s the case, then the best advice is work with a vendor who has experience integrating [the technology],” Heldenberg says. “Use their experience to benefit your business. You won’t have the same hiccups and challenges you would with a less-experienced vendor.”
Jeremy Van Puffelen grew up in a family-owned contract warehousing business and is now president of that firm, Prism Logistics. As a third-party logistics service provider (3PL), Prism operates a network of more than 2 million square feet of warehouse space in Northern California, serving clients in the consumer packaged goods (CPG), food and beverage, retail, and manufacturing sectors.
During his 21 years working at the family firm, Van Puffelen has taken on many of the jobs that are part of running a warehousing business, including custodial functions, operations, facilities management, business development, customer service, executive leadership, and team building. Since 2021, he has also served on the board of directors of the International Warehouse Logistics Association (IWLA), a trade organization for contract warehousing and logistics service providers.
Q: How would you describe the current state of the contract warehouse industry?
A: I think the current state of the industry is strong. For those that have been focused on building good client relationships over the years, I think it’s a really exciting time. Coming out of all the challenges of the past few years, I think there’s a lot of opportunity for growth and deeper partnerships. It’s fun to see the automation and AI (artificial intelligence) integration starting to evolve [in a way that’s] similar to what we saw with WMS (warehouse management systems) in the early 2000s.
Q: You are now president of your family firm. Is it an advantage having grown up in the business as opposed to working elsewhere?
A: I definitely believe it was an advantage growing up in the business. Whether it’s working with family or someone else in the industry, there’s always an advantage when you have mentors[to guide] you. I’ve been blessed to have several mentors, some in the industry, others just in life, and I’m thankful that they were willing to mentor me and that I was willing to listen to them.
Q: What are the biggest challenges currently facing 3PLs, and how are you addressing them?
A: Labor and legislation are both tough right now. The two seem to have a lot to do with each other, and it can make it tough to find and retain people. So I think we’ll see more and more automation of processes industrywide.
Q: Third-party service providers often must handle a wide variety of products for a lot of different clients. Does this variety make it difficult to invest in automation and other new technologies?
A: It can make things more difficult when looking at certain automation, but it’s in the “difficult” that a lot of opportunities lie. It would be tough to find a single solution that fits every client’s needs, but there are always opportunities to improve in certain areas. It just takes a bit of vision and commitment, and a willingness to invest in your own long-term success.
Q: As a 3PL, what do you look for when selecting the clients you work with?
A: Quality relationships that will last a long time. When both parties are happy and working together in the same direction, everyone wins.
Q: You’ve been a board member of the International Warehouse Logistics Association since 2021. Why is your involvement with this organization important to you?
A: I think it’s important to understand what’s happening in the industry. IWLA is a great resource for staying up to date and getting a solid education when it comes to the latest logistics trends. I also think it’s important to give back and pass along what we’ve learned to those just getting started in the business. As important as it is to have a mentor, it’s just as important to mentor and help others.
“While there have been some signs of tightening in consumer spending, September’s numbers show consumers are willing to spend where they see value,” NRF Chief Economist Jack Kleinhenz said in a release. “September sales come amid the recent trend of payroll gains and other positive economic signs. Clearly, consumers continue to carry the economy, and conditions for the retail sector remain favorable as we move into the holiday season.”
The Census Bureau said overall retail sales in September were up 0.4% seasonally adjusted month over month and up 1.7% unadjusted year over year. That compared with increases of 0.1% month over month and 2.2% year over year in August.
Likewise, September’s core retail sales as defined by NRF — based on the Census data but excluding automobile dealers, gasoline stations and restaurants — were up 0.7% seasonally adjusted month over month and up 2.4% unadjusted year over year. NRF is now forecasting that 2024 holiday sales will increase between 2.5% and 3.5% over the same time last year.
Despite those upward trends, consumer resilience isn’t a free pass for retailers to underinvest in their stores by overlooking labor, customer experience tech, or digital transformation, several analysts warned.
"The 2024 holiday season offers more ‘normalcy’ for retailers with inflation cooling. Still, there is no doubt that consumers continue to seek value. Promotions in general will play a larger role in the 2024 holiday season. Retailers are dealing with shrinking shopper loyalties, a larger number of competitors across more channels – and, of course, a more dynamic landscape where prices are shifting more frequently to win over consumers who are looking for great deals,” Matt Pavich, senior director of strategy & innovation at pricing optimization solutions provider Revionics, said in an email.
Nikki Baird, VP of strategy & product at retail technology company Aptos, likewise said that retailers need to keep their focus on improving their value proposition and customer experience. “Retailers aren’t just competing with other retailers when it comes to consumers’ discretionary spending. If consumers feel like the shopping experience isn’t worth their time and effort, they are going to spend their money elsewhere. A trip to Italy, a dinner out, catching the latest Blake Lively and Ryan Reynolds films — there is no shortage of ways that consumers can spend their discretionary dollars,” she said.

A real-time business is one that uses trusted, real-time data to enable people and systems to make real-time decisions, Peter Weill, the chairman of MIT’s Center for Information Systems Research (CISR), said at the “IFS Unleashed” show in Orlando.
By adopting that strategy, they gain three major capabilities, he said in a session titled “Becoming a Real-Time Business: Unlocking the Transformative Power of Digital, Data, and AI.” They are:
business model agility without needing a change management program to implement it
seamless digital customer journeys via self-service, automated, or assisted multi-product, multichannel experiences
thoughtful employee experiences enabled by technology empowered teams
And according to Weill, MIT’s studies show that adopting that real-time data stance is not restricted just to digital or tech-native businesses. Rather, it can produce successful results for companies in any sector that are able to apply the approach better than their immediate competitors.
“ExxonMobil is uniquely placed to understand the biggest opportunities in improving energy supply chains, from more accurate sales and operations planning, increased agility in field operations, effective management of enormous transportation networks and adapting quickly to complex regulatory environments,” John Sicard, Kinaxis CEO, said in a release.
Specifically, Kinaxis and ExxonMobil said they will focus on a supply and demand planning solution for the complicated fuel commodities market which has no industry-wide standard and which relies heavily on spreadsheets and other manual methods. The solution will enable integrated refinery-to-customer planning with timely data for the most accurate supply/demand planning, balancing and signaling.
The benefits of that approach could include automated data visibility, improved inventory management and terminal replenishment, and enhanced supply scenario planning that are expected to enable arbitrage opportunities and decrease supply costs.
And in the chemicals and lubricants space, the companies are developing an advanced planning solution that provides manufacturing and logistics constraints management coupled with scenario modelling and evaluation.
“Last year, we brought together all ExxonMobil supply chain activities and expertise into one centralized organization, creating one of the largest supply chain operations in the world, and through this identified critical solution gaps to enable our businesses to capture additional value,” said Staale Gjervik, supply chain president, ExxonMobil Global Services Company. “Collaborating with Kinaxis, a leading supply chain technology provider, is instrumental in providing solutions for a large and complex business like ours.”
