Introducing Business 4.0
How TimkenSteel took Industry 4.0 – a traditionally technical concept – and used it to revolutionize supply chains and reliability
_____________________________________________________________________________________
Challenge: An historic global supply chain crisis brought on by the COVID-19 pandemic shed light on the inefficiencies of traditional procurement practices. Change agents at TimkenSteel saw it as an opportunity to rip off the proverbial Band-Aid and “lean up” through what Supply Chain and Commodity Modeling Manager Nicholas Galbincea calls an “optimization mentality.”
Solution: TimkenSteel has since implemented “Business 4.0” – an initiative led by Galbincea that applies the principles of Industry 4.0 to maintenance, reliability and operations (MRO). JMP® statistical discovery software became a critical partner in the company’s transformation as it provided a lean solution to automate and consolidate entire workflows into one end-to-end platform.
Results: Within just 6 months of rolling out the initiative in JMP, Galbincea says the company saved more than $700,000 – a figure he anticipates will only grow as he continues to refine the model. In addition to financial value, MRO processes have been dramatically streamlined, enabling TimkenSteel to move from processing 100 items per week to over 13,000 in the same amount of time. “I built the model, saw it work and saw it profit the company,” Galbincea reflects. “To me, that's awesome. That’s making a difference.”

“It’s very easy in any industry with as much history [as steel manufacturing] to get caught up in doing things the same way year after year. But that just can't happen anymore,” says Nicholas Galbincea, TimkenSteel’s Supply Chain and Commodity Modeling Manager. “One of the most unhealthy things you can say in any business is: ‘This is how we've always been doing it.’”
TimkenSteel – a leader in high-performance alloy steel bar and tubing – has in recent years embraced ambitious sustainability targets and is leveraging lean practices and continuous improvement to reduce environmental impact and improve the efficiency of its annual melt of roughly 1.2 million tons.
Thanks to Galbincea’s unique vision and the innovation-minded leadership backing him, TimkenSteel is borrowing a strategy from the world of engineering – Industry 4.0, a smart manufacturing philosophy – to transform other aspects of the business. This optimization mindset is now helping the company gain traction as an early adopter of big data in maintenance, reliability and operations (MRO).
“Analytics is the future, and that future is now,” says Galbincea. “If you don't get on board, you're going to be left in the dust. And I know that sounds cliché, but it's truer now than ever.”
Scaling lean ideals beyond engineering
Galbincea, who trained in mechanical engineering and materials science, brought a computational perspective to TimkenSteel where he started in an R&D role. In early 2020, he moved into the company’s purchasing department and now manages direct, consumable materials procurement. The timing of this move, however, isn’t lost on Galbincea.
“Lo and behold, it would be a crash course in one of the hardest global supply chain issues that had probably ever faced the world,” he says. The global COVID-19 pandemic, which quickly spread globally in 2020, caused the most significant supply chain crisis in the history of the post-industrial world. Manufacturers in every industry on every continent were hit by staggering disruptions beyond their control, and TimkenSteel was no exception.
Faced with an historic challenge only weeks into his new role in commodity management, Galbincea saw an opportunity for TimkenSteel to make a clean break with the way supply chains were managed in the past and instead embrace analytics transformation. “It made total sense. It's not rocket science to correlate what we should be buying – our inventory – based on the demand and the needs of the company."
Galbincea’s plan was to use statistical methods common within Industry 4.0 to optimize MRO. “It's taking an analytical approach to what we should be consuming based on a master plan forecast and correlating that directly with what we should be buying,” he explains. “I started applying these analytical models to ask how we could reduce our inventory. 2020 was the time to reduce inventory and lean up because business was slow.”
Having studied computational approaches to materials science during his graduate training, Galbincea was no stranger to the idea of Industry 4.0 – at least in technical applications. Applying algorithmic approaches in purchasing, however, was relatively uncharted territory, not just at TimkenSteel but across the entire industry.
“We began optimizing our inventory for the current business situation, and here we are two years from that [inflection point] and the company is doing very well. 2021 was actually a record year for TimkenSteel since its inception,” he says.
JMP is an all-in-one solution for automating data workflows
At any given time, TimkenSteel houses inventory worth millions of dollars in a controlled warehouse setting. Everything from pumps to nuts and bolts must be on hand in the event of a breakage or failure in the manufacturing system so as to avoid costly downtime. Managing thousands of inventory items can be daunting, even when the global supply chain is running without disruption.
Traditionally, inventory management is the purview of a team working by hand to index supply and initiate procurement. However, TimkenSteel’s lean approach meant Galbincea would need to create new efficiencies through statistics.
“[At first] I was building inventory models for specific direct commodities because to do it manually was too cumbersome without a large team,” Galbincea recalls. That’s when he had an idea: automate the entire system. “I said let's build a model. Let's build an algorithm to handle the whole thing!” To do this, he would need a tool, and that tool was JMP®.
Having used the statistical discovery software in his prior R&D role, Galbincea says JMP was the natural choice. “JMP in itself is a very user-friendly tool. Just from an interface standpoint, it’s beautiful. It's relatively easy to navigate and start graphing your data, doing linear correlations. Even machine learning – the neural net module – is straightforward. You might not understand what all the metrics and parameters mean, but you can run it in JMP.”
Moreover, he adds, the learning curve associated with any new tool is eased considerably in JMP by intuitive instructional resources. “The help tab at the top has short tutorials and the search tool is especially helpful for figuring out which formulas are already built in,” he explains. “JMP has a huge database of [readymade] formulas that you can use instead of having to code or figure it out yourself.”
“The visualization is great too. I can't give enough kudos over how easy Graph Builder is to use. Showing data with a graphical representation is so much more powerful than just presenting numbers, and with inventory, I can show our management visually – and in a single graph – where the model is saying our max should be. It’s very powerful because it makes sense.”
$700,000 of savings in 6 months
Starting with major commodities – materials used in the steelmaking process, from refractory consumables to mill tooling and tube mills – Galbincea began developing an MRO optimization model. “With JMP, I was able to query from the controlled warehouse's database, ensuring that the physical and digital inventory aligned,” he says. “From the Query Builder, I then used JMP to massage these data tables and do a bunch of linkages to [identify] lead time," he explains. This workflow was easily automated with a few scripts.
Now, with the click of a button, the system accesses and queries data from TimkenSteel’s database, runs an optimization algorithm for each item based on historical consumption and current lead time calculations, and produces a set of recommendations: when items should be reordered and in what quantity. When the balance of any one inventory item drops below a certain threshold, the system will trigger a buy. Thresholds are set so as to account for global supply chain events, including longer than average lead times.
“Working in JMP, I was able to, over several months to a year, build [an MRO] model, [automate] data query, work out bugs and then go live with it,” he says. “Now it's as simple as clicking, running two scripts, and [the dashboard] spits out new numbers [taking into account] updated lead times and each item's most recent but still historical consumption.”
The model went into effect in March 2022 and within its first 6 months alone, Galbincea says, generated more than $700,000 in savings. “It’s a real golden goose because over time, it will keep saving us money,” he adds.
A living, breathing model delivers value to the company year over year
Prior to the introduction of Galbincea’s model, a key failure point in supply chain management was the human error inevitable in any physical inventory cataloging process. Now with much of the process automated – eliminating opportunities for human error to adversely affect data quality – physical and digital inventories are better aligned. And better data quality supports more accurate, optimized purchasing. As a result, Galbincea says, lead time and reliability have also improved. The system now processes a buy with a lead time calculation that over time adds to supply chain knowledge by continuously refining the algorithm.
“The model is living and breathing – it keeps getting updated along with the data,” Galbincea says. “Lead times changed this year with demand so high and supply still being choked because of labor, inflation, fuel costs, transportation and freight… And [with the model], boom – all those numbers are updated instantaneously.”
In its second phase, Galbincea is developing a more advanced reliability model that will enable forecasting and optimize a preventative maintenance schedule and related purchasing. “That's where things start getting really cool,” he says.
There will likely be more AI and machine learning involved in this next phase, as failures are not always linear from a data perspective. “When you can correlate preventative maintenance with your buying schedule, then you can really optimize risk and what you carry on hand.”
Automation enables engineers to invest their time in more value-adding tasks
More even than a reduction in procurement budget, Galbincea’s innovation means TimkenSteel is also saving on engineering labor hours that were previously devoted to repetitive manual tasks. Whereas queries were previously one-offs, standard scripts in JMP now enable engineers to query the data as frequently as they need without investing additional time.
“Five years ago, an engineer would query and massage data manually. Now it's all automated, so you can see how [this project] has been proof of concept,” he says, adding that achieving TimkenSteel’s current level of optimization manually would have been so time-consuming even for a team of engineers that it would not have added value.
“It's not just in the dollar amount [that we see value from the model],” Galbincea explains. “It's also freeing people up to solve other problems and create value through new projects. When you free up that employee's time, they can work on more value-added tasks.”
“If you can automate it, there's no excuse to do it manually”
In transforming supply chain management, Galbincea and his advocates at TimkenSteel have perhaps hit upon the next industrial revolution – one that involves the entire business enterprise. “Ultimately, if you can automate it, there's no excuse to do it manually,” Galbincea concludes. “That’s Business 4.0: digitize the entire enterprise and you’ll be able to analyze almost any facet of your business and see potential optimization opportunities. You’ll see where you should focus [time and investment], and you'll get the most bang for your buck.”
