Big data can guide big maintenance decisions: Panel
Posted: April 14, 2016
MISSISSAUGA, ON – The electronic revolution is a reality in the trucking industry. Electronic Control Modules now feed data from engines and transmissions alike. Maintenance software can spit out reams of reports, measuring just about every imaginable operating parameter.
As important as all the underlying data can be, however, the secret is to turn it into actionable information.
Speakers during the inaugural Canadian Fleet Maintenance Summit offered insights into ways that data can guide Predictive Maintenance activities. Put another way, it can help address challenges before breakdowns occur. And the benefits of big data – the massive datasets that support analytics — are not limited to big businesses.
“The small fleets can behave as big ones if they embrace the tools that the dealers and the OEM have today,” said Skip Yeakel, principal engineer – government industry academia link for Volvo Group North America. He referred to his company’s Uptime Centre, and the way it diagnoses issues remotely, as an example.
Even though larger fleets have more resources to explore raw data, smaller operations still have the opportunity to look at single reports or receive alerts, added Larry Jordan, vice president – product management for Zonar, a supplier of fleet management software. These are the details that can help avoid breakdowns or delays at weigh stations. “It’s not just the uptime, but it’s the availability of the truck, the availability of the driver, and the availability of the product you’re delivering.”
There were certainly fans of such ideas. “In the perfect world, I’d like to see a truck tell me what’s wrong with it,” said Kirk Altrichter, vice president – maintenance for Nebraska-based Crete Carrier.
Some of the biggest challenges appear to involve sorting through the reams of available data, or finding the useful tidbits hiding in file folders. Even gathering the data can be a problem. “Why am I re-keying information?” Altrichter mused. “Warranty is still a very manual process, even if you have agreements loaded into the system.” And where manufacturers often understand their own brands, their systems often struggle to communicate with those used by competing nameplates, he said.
“Organizations are learning the same thing over and over again because they never took the information and turned it into knowledge,” added Ric Bedard, president of Toronto-based Cetaris, a supplier of fleet maintenance software.
There can also be too much of a good thing, leading to information overload. Altrichter learned that the hard way when asking to be alerted about any monitored fault codes. “We ended up turning it off quite quickly.” The goal instead is trying to identify the codes that require immediate attention, and those that can wait to the next Preventive Maintenance cycle, he said.
Yves Maurais, Groupe Robert’s technical director – asset management, purchasing and conformity, stressed the need to set specific goals for the data being collected. “Once you know what you’re looking for, it’s easy to get the correct tools,” he said. And he encouraged maintenance managers to review new technologies at least one day a week, even looking beyond North America since Original Equipment Manufacturers are increasingly global. Technologies are developed around the world.
Smaller fleets, said Marais, might want to focus on the data and systems linked to regulations. “Make sure you’re compliant,” he said. “The rest would be icing on the cake.”
Using standardized Vehicle Maintenance Reporting Standards (VMRS) can help make sense of the “big data” that guides operational issues, said Michael Riemer, vice president – products and channel marketing with Decisiv Inc., another software provider. That’s when a maintenance manager’s role shifts from managing parts to managing processes, and how useful information can be available at the point of service.
Then there is the question of the quality of the data being used. Feed garbage in, and any system will spit garbage back out. “Step back and make sure the fundamental numbers are right before you build your decisions around those numbers,” warned Bedard.
Another challenge is that vehicle systems, which might work well independently, often don’t work well together, Maurais added. “At some point we have to make sure that everyone speaks together.”
“Whatever happens, I hope it’s a simplified version of what happens in a truck right now,” he said, referring to technicians who now have to juggle an array of connections and different software platforms when working on mixed fleets. “Right now it’s a nightmare.”
Above all, the ultimate goals of the exercise need to be unique to every fleet, said Riemer. There is simply a difference between the Preventive Maintenance schedules recommended by a manufacturer, and what might actually be required in a punshing environment like Northern Alberta. “Make it specific to your operation.”
In the midst of it all, there is a need to ensure the data is controlled, especially as more items are connected through the Internet of Things. “You have to focus on access as well as the security. It’s a fine balance,” said Riemer. Jeep discovered this the hard way when hackers demonstrated how they could control a vehicle on the road. “If you design it right, you shouldn’t have the type of issues that Jeep had.”
The industry might even need to take care and ensure emerging systems don’t interfere with each other. That isn’t a problem now, said Altrichter. “I don’t know what’s coming tomorrow.”
