Supply Chain Automation Surges

Tags: Warehousing, Last Mile Delivery, Supply Chain

Supply chain automation is gaining ground, particularly in warehousing and middle- and last-mile logistics.

While many companies are automating different areas of the supply chain—from purchasing all the way through to last-mile delivery—it's not quite as widespread and prevalent as you might think.

But automation is definitely on the radar, according to APQC, a Houston-based nonprofit that provides members with benchmarking research. In fact, 84 percent of those responding to the organization's 2018 Supply Chain Management Priorities and Challenges survey say that digitalization will have the biggest impact on the supply chain in the next three years.

Awareness, however, doesn't necessarily translate to action. "A lot of hype and conversation might lead you to believe that digitalization is reality," says Marisa Brown, a senior principal research lead at APQC. "The truth is that it is not yet widespread."

Implementation varies across different parts of the supply chain, including planning, procurement, manufacturing, and logistics. "We're seeing automation mostly in plants and warehouses," says Alberto Oca, a principal in the operations practice at consulting firm A.T. Kearney.

"There has been a shift in where automation is being used," he adds. "It's not just moving through the first mile—it's also in the middle and the last mile."

Noting the well-established impact of the Amazon effect, shippers in particular are looking to automation to "reduce the touches," Oca says.

Many companies are turning to robotics to reduce those touches and to handle repetitive tasks while improving efficiency.

Repeat Business

"The trend is to drive out human labor that is repetitive," says Steve Sheiner, vice president of business development at Brain Corporation, a company that helps robots navigate. "Efficiency is critical to survival. Companies have to adapt rapidly, and if they're not adopting some form of robotics, they will not be able to compete."

Supply chain automation isn't limited to finding more efficient ways to pick or move products, though. Gathering data for decision-making was—and still is—an early driver of automation.

QiO Technologies provides software that pulls data from legacy systems and other sources and harmonizes it so that it can be used to guide automated processes and improve decision-making. As an example, the company cites the world's largest glass manufacturer, which uses industrial furnaces to produce more than 5,000 products daily.

The temperature of its manufacturing furnace is raised for larger products and lowered for smaller ones. With smart energy meters installed at the line, the manufacturer gets data showing how much energy each furnace consumes throughout the process.

Integrating that information with production schedules from enterprise resource planning systems digitally, rather than manually, allows the fusion of the two sets so that the company can optimize energy per product manufactured.

"Our technology lets that kind of data aggregation happen on a massive scale," says Gary Chandler, consulting services director at the UK-based firm.

In warehousing and shipping, automation serves several purposes that include helping to:

  • Reduce the impact of a labor shortage
  • Keep labor costs down
  • Improve productivity
  • Improve efficiency

At Catania Oils, a Massachusetts-based blender and packer of cooking oils, automation streamlines the movement of products from production in the back of the building to distribution in the front. Five overhead conveyors now carry individual boxes of products from the production line to palletizers in the front. Automation has made it possible for the company to recently shift from five palletizers to two.

This approach creates an "accumulation area" where cases queue up for each palletizer. When one conveyor fills up, the system tells the palletizer that line is ready. The palletizer knows that the company is running that product at, for example, 36 cases on a pallet, and automatically changes all its parameters for the products it's now receiving.

"In the past, we had a lot of forklifts moving around constantly from back to front," says Dan Brackett, director of manufacturing and engineering. "Now, products are carried three-fourths of the way to the shipping area on overhead conveyors ."

The new automation has increased each line's yield by 20 percent, he adds.

Autonomous Trucks

Contract logistics provider DHL Supply Chain is testing autonomous pallet trucks that include vision-guided and self-driving options for that long distance from plant to warehouse.

"In some cases, product shuttles through a long tunnel or corridor to the warehouse," says Adrian Kumar, vice president of solutions design in Ohio. "Automating that horizontal travel frees up the pallet truck driver to do more skilled work related to that navigation."

Moving materials with semi-automated forklifts—something Catania plans to consider in the future—helps improve productivity while reducing operator fatigue. With Crown Equipment's remote order picking system, technology allows the operator to move the vehicle forward a pre-determined distance with the touch of a button without getting back on the forklift. The process keeps the forklift in front of the employee.

"It might not seem like much, but the repetitive task of getting on and off that platform—continually stepping up and down—adds up to thousands of steps every day," says Jim Gaskell, director of global technology business development at the Ohio forklift manufacturer.

Forklift automation improves productivity by 10 to 20 percent, depending on the application. "If the improvement is less than 10 percent, there's usually a process issue that we need to address before the user reaches optimal performance," Gaskell adds.

Tricked Out Trucks

Forklifts are also increasingly equipped with automated mobile devices.

"Forklifts used to include 20-pound computers running with telnet systems connected to the warehouse management system; now they're using tablets," says Marco Nielsen, vice president of managed mobility services at Stratix Corporation in Georgia.

In one case, Stratix was even able to equip a forklift operating in a freezer—less than ideal operating conditions for a mobile device—with an iPad. "We added a heated pad and mounted the iPad inside it and it worked," Nielsen says.

ShipMonk, a Florida software company that offers third-party logistics services, has automated the picking process with the first e-commerce automated storage and retrieval machine in the United States. Each machine holds 7,000 SKUs and offers distinct advantages in a segment where orders must be picked and shipped quickly.

"Machines are more consistent and accurate than humans and don't call in sick," says Kevin Sides, chief revenue officer.

Automation extends to transportation and delivery, too—just ask any truck driver. The electronic logging device (ELD) mandate that went into effect at the end of 2017 requires drivers to log their hours with a digital device that collects and transmits data.

Automating the Last Mile

Automation is essential for last-mile delivery as well, with software managing logistical algorithms and smartphone apps communicating package pickup and delivery details.

Delaware's DeliveryCircle uses proprietary software to automate the package and driver matching process for deliveries in verticals that include automotive, medical, pharmaceutical, and retail in 19 cities.

"We don't have a lot of operations people because the system keeps an eye on things; we don't have to," says CEO Vijaya Rao. "If our technology was less sophisticated, we would have at least double or triple the number of people in operations."

For example, if a pickup is scheduled for noon and it hasn't happened by 12:05 pm, the system automatically triggers a message that there might be a delay.

DeliveryCircle's software knows which drivers are certified to transport goods to and from blood banks, labs, and hospitals; who can deliver pharmaceuticals to hospitals and consumers; and which people drive autos, cargo and mini-vans, or box trucks. The system automatically matches driver certification, vehicle size, and goods to be delivered.

Rao expects future delivery automation to involve tracking chips added to packages to communicate continually without scanning.

Still, as sophisticated as it all sounds, "The vast majority of operations are still relatively conventional in nature," says Kumar.

"There's a lot of different technology out there, but many operations still look the same way they did 20 years ago," he adds. "The difference might be that companies pepper in different innovations here and there."
