The Right Questions To Ask When Evaluating An AI Condition Monitoring Solution
Illustration: © AI For All
A discussion has been sparked on the best questions for manufacturers to ask when they are out to invest in an AI-driven manufacturing solution. After all, with few regulations and shifting vocabularies, many vendors are using whatever terms to make a sale – when in fact their AI is weak or non-existent.
So here are some questions to help you probe beneath the marketing fluff and understand what you’re buying:
What is the Quality of Data and Level of Insights They Are Able to Generate?
Today, a combination of high-bandwidth wireless protocols, hourly sampling, and purpose-built Industrial AI can work to detect and diagnose a wide range of faults – both acute and gradual.
However, many solutions typically collect and send much lower-quality data, which severely limits their ability to provide timely and accurate diagnostics. In addition, other algorithmic approaches like ISO and adaptive thresholds result in high false alarms (70 percent) and misses (15 percent) which puts you at risk of unplanned downtime.
How Accurate Are the Alerts? And Are These Alerts Predictive and Prescriptive?
Ideally, the accuracy of the alerts should be dependable, scalable, and guaranteed. Such accuracy is further verified and made stronger if these alerts are predictive and prescriptive.
Only a true prescriptive diagnostics platform – one that loops in both machine and verifying human intelligence (Hybrid Intelligence) – can achieve consistent accurate metrics that are dependable at scale. With offshored back office manual analysis there are too many variances in the quality of analysis to make guaranteed outcomes possible.
How Many Levels of AI and Human Intelligence Do They Employ For Their Condition Monitoring?
To get deep, specific, and reliable insights into your machines, you need different levels of Hybrid Intelligence (AI and human) running in tandem, such as:
- Anomaly detection (such as an algorithm focused on where the issue is, and when did it happen)
- Fault detection (such as an algorithm focused on what’s the issue and cause, and how can it be fixed)
- Severity analysis (such as an algorithm focused on time until failure and how bad it will be)
- Expert intelligence (actual humans, such as vibration analysts and/or reliability engineers, providing an additional layer of support and interpretation for customers)
How Quickly Does Their AI Detect and Diagnose Machine Failures? What is Their Rate of Misses and False Alarms?
Direct pattern recognition of equipment behavior can accurately deduce failure mode and root cause with an accuracy that leans as close as possible to 100 percent. If you combine this type of AI with a Category III and IV vibration analysis team, you can detect and be alerted of failures rapidly from day one, even from machines less than 24 hours away from failure.
In comparison, threshold-based systems generate a significant volume of false alerts which when combined with slower response times from the back-office analyst team, makes it harder to focus on the machines that are actually failing.
Are Fault Diagnostics Reliable and Accurate Enough to be Backed with an Insurance Policy?
When it comes to reliability, you need reliable diagnostics. Without that, your team would be flying blind and prone to make expensive mistakes. A lot of AI solutions are great, but almost always stumble with edge cases, misses, or inaccuracies.
To be sure that the AI solution you are buying is reliable, look for those that come with a diagnostics guarantee – in other words, if the diagnostics are wrong, you can file an insurance claim for any related losses.
Can They Provide Accurate Diagnostics Immediately After Deployment or do They Need to Custom-Build an AI Model For You After the First Failure?
If a solution already has hundreds of millions of hours of recorded machine data across hundreds of asset types and failure modes, the vendor won’t have to wait until your machine fails in order to create an algorithm. So be sure to understand what it means to “set the baseline” before you deploy. In other words, if the solution is learning and diagnosing from a large data set, value can happen faster. If that solution needs to start at zero, you have a longer road ahead of you before you start seeing value.
In Conclusion…
There are more and more options out there and it can be daunting. But by asking these questions, you can be more sure you are choosing the best option that can drive value and scale across your company. Because when new technologies fail or are too difficult to adopt, it just sets everything back. These questions will get you the answers you need to select the right machine health solution.
