Production processes come to a grinding halt when equipment breaks down. This results in production delays, costs incurred to fix the machine, and opportunity costs. The production process cannot proceed until the maintenance activity on the faulty machine is complete — unless you have provisioned equipment redundancy. [Read more…]
Asset reliability programs are a set of initiatives for tracking the health, effectiveness and locations of both fixed and moveable assets. It involves routine maintenance, as well as the collection and analysis of equipment operating data to measure efficiency throughout their useful lives.
A good reliability engineering program provides insight on the frequency of asset failures, cost of operation, maintenance and repair, and the quality of maintenance work. Over time, an organization needs to evaluate metrics such as mean time between failures (MTBF), mean time to repair (MTTR), and mean time to failure (MTTF) to ascertain the suitability of the selected maintenance strategy.

Almost all maintenance, reliability or asset management professionals have heard of reliability engineering. But what is reliability engineering? A quick google search will return the following definition “Reliability Engineering is engineering that emphasizes dependability in the lifecycle management of a product. Dependability, or reliability, describes the ability of a system or component to function under stated conditions for a specified period of time.”

What does the word statistics bring to mind when you hear it? Horrible high school classes that you sat through wondering why do I need this stuff? Complex math problems what were almost impossible to figure out? Or is it nonsense that is only used in political polls?
Statistics are used in every aspect of Reliability Engineering. So if you don’t have a good relationship with statistics, I highly recommend that you are starting investing time in building your knowledge in statistics. [Read more…]
At first glance, a computerized maintenance management system (CMMS) and Failure Modes And Effects Analysis (FMEA) may appear to be worlds apart. But take a deeper dive, and it’s easy to see that they both share a common component: data. The core of any CMMS is defined by gigabytes of data that guarantee its usefulness and functionality, while the success of the systematic steps in FMEA depends on good quality data.
Let’s face it, the field of reliability engineering is diverse and full of statistics, models and detailed analysis. The detailed calculations, the building of models and analysis, have been performed with great success in the past and currently. The models built through manual calculation have been successful and demonstrated the importance of reliability engineering.
Let’s face it, your technicians have been entering data into the CMMS for years, but you haven’t been able to use it to make improvements. Is it because the data isn’t codified or it doesn’t have the right data points? Generally, this is how most maintenance managers will view their data, but it is incorrect. The CMMS does have data that you can use almost immediately. [Read more…]
I am a parent of two young children. As a result of my experiences as a mom, I feel that parents make great Reliability Engineers because there are so many shared skill sets. Please enjoy this lighthearted comparison to start your week out with a little humor.
First, I have to point out the development of a brand new Reliability Engineer requires the same skills of lubrication and vibration that the conception of a child requires. [Read more…]
If a manufacturing plant was a human brain: Maintenance would be the repairing blood flow, Operations would be the electricity sparking between synapses, and Reliability would be the conscience. [Read more…]
A topic that often comes up lately is high turnover, especially the perception that this is common and desirable among millennials. Born in the mid eighties, I am right on the cusp between millennial and Generation X, and I am one of the aforementioned employees with a high turnover history. A specialized Reliability Engineer with nearly ten years of work experience, I have rarely stayed with a company much over two years. I never intended to be a person who moved between companies so regularly, it just kind of happened. [Read more…]
In a single meeting, you may need to structure a reliability model, create estimates, outline test plans, and discuss a field failure. The breadth of tools and knowledge to be effective is staggering.
No two problems, questions, situations, or industries are the same. Thus, the solutions you provide must differ as well. If you enjoy a complete set of reliability engineering tools at your disposal, you are well situated to address any question.
Generally, I do not talk about statistics before 10am – it’s not polite.
As a reliability professional, statistics is a central feature of the value I bring to the team. And, not just the reliability statistics, all stats. It continues to amaze me how many engineers, scientists, and professionals tend to avoid statistics. [Read more…]
