In the previous post, the basics of a Reliability Block Diagram were covered using simple Series or Parallel paths. In real life, most systems or processes are not that simple and require a different level or type of models, often used in combination with other types.
So in our continued exploration of RBDs, let’s explore a few different models that may be used. [Read more…]
I was coaching one of the national oil companies in the Middle East, offering mentorship to the director of their operational excellence program. He was frustrated because he had invested considerable funds building a team of sixty Lean Six Sigma Black Belts over a nine-month period, and they had not yet worked on—much less completed—any project nor had they realized any benefit to the company.
Even worse, while these newly-minted Black Belts were sitting idle without the opportunity to use their new-found skillsets, some became frustrated themselves and left the company—taking the company’s investment with them. [Read more…]
I was recently in New York City for work. I stopped by to see a friend in the area. He said “I have something interesting to show you.” I was pretty excited because when Mark says “I have something interesting to show you.” you know it is going to be good. He’s a writer and his passion is finding strange and interesting things. My personal Indiana Jones. Many days he wakes up and just gives himself some adventure assignment and the goes searching for it.
In this video we walk through what an asset hierarchy is as well as the parent/child relationship often built as part of the asset hierarchy. [Read more…]
Watch as I explain what it is. (Hint…it’s simple, but it’s not always easy!) [Read more…]
The gage measurements are expected to be stable, meaning the gage should provide consistent readings. Some random variation due to random error is expected. However, gage measurements change with time or because the gage is damaged. The gage stability can be checked by measuring a known reference.
In this article, it is shown how to use control charts to assess gage stability.
In the article Calculating Network Reliability the lack of published analytical solution for dual-ring network reliability was highlighted. This article provides a neat solution and further challenges readers to offer their proof or prior publication reference. The solution and the author’s general proof will be presented at RAMS 2020.
We offer three main services – projects, program management and training. This video illustrates the typical progression of service use through a case study. Don’t be afraid to skip ahead in the process! [Read more…]
60% of failures and safety issues can be prevented by ensuring there is a robust equipment design and that Maintenance & Reliability is taken into account during the design phase. Equipment should be designed with the following in mind:
ISO 31000 is the International Enterprise Risk Management (ERM) framework developed in 2009 by the International Organization for Standardization (ISO). Its use in government is increasing. The reason for the increase is that governments around the world are recognizing that risk events are increasing in frequency and cost. For instance, Hurricane Harvey impacted the States of Texas, Louisiana, Mississippi, Tennessee and Kentucky. It flooded 19 water systems, 31 waste water systems and 13 super fund sites spreading toxic waste throughout the region. It cost Texas $125 billion dollars. (1) [Read more…]
We discuss what traits make successful reliability journeys happen. This is part 2 of 2. (part 1 is here) [Read more…]
Who knew that the ocean could teach us something about Reliability Centered Maintenance (RCM). Join me on Daytona Beach and we’ll debunk one of the most common misconceptions about the process. [Read more…]
Evolutionary operations is an approach to design of experiments that is not commonly known. Where can it apply? May it be useful in your situation? [Read more…]
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.
The rule is simple. For high-risk issues, the FMEA team needs to properly identify the cause(s) and associated failure mechanism(s). So, what exactly is a failure mechanism?
