Taking Reliability Block Diagrams to the Next Level

Using RBDs to model different systems and circumstances

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.


K out of N Models is […]

How To Evaluate The Reliability Of A System Or Process

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;


  • Designed for Fault Tolerance
  • Designed to Fail Safely
  • Designed with early warning of the failure to the user
  • Designed with a built-in diagnostic system to identify fault location
  • Designed to […]

The Role of Software In Reliability Engineering

Deciding if Software is Right For Your Program

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.

In today’s environment where multiple models may be required for slight variants of a design or […]

The Role of Statistics in Reliability Engineering

This Isn’t Your High School Statistics Course

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 […]

What is Reliability Engineering?

An Overview of the Reliability Engineering Discipline

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.”

This definition seems simple enough in the fact that the reliability […]

Should You Worry About IoT If You Don’t Have the Basics Down?

What Good Is The Data If You Don’t Know What To Do With It?

As maintenance, reliability, and asset management professionals, we are in an amazing time.  We can collect virtually limitless amounts of data on the condition of our assets.  With this data, we can determine the exact condition of the assets, predict when the next failure is likely to occur and how it will occur.  Besides, with all of this data, we can move to prescriptive maintenance, where the maintenance actions are determined based on the asset condition, not a predetermined […]

The Top 3 Analysis Techniques To Use When Performing a PM Optimization

Performing a PM Optimization is not always as simple as it sounds.  Often a Maintenance Planner will assemble a team of technicians to ask what is value-added and what is missing from a PM Routine.   While these may be good questions to ask before diving into an analysis, or after an analysis, it does not base the answers on data.   Basing the PM Routine on data, not intuition is critical to the long-term success of any organization.

To perform a PM Optimization, there are three main types of analysis to focus on the […]

Linking Failure Codes To A Proactive Maintenance Strategy

Using Failure Data to Drive Sustainable Improvements

If you are lucky enough to have good failure data history in your CMMS, you are one of the few.  But even if you have the data, can you use it to make a difference to your organization?  Obviously, the data can be used to perform certain reliability engineering analyses, but what can those without reliability engineering experience do with the data?

Bad Actor / Pareto Analysis

Two simple analysis that anyone can use with their failure history are;

  • A Bad Actor analysis is identifying equipment that is […]

Collecting Failure Data: A Practical Approach

How to collect the failure data needed to drive improved plant performance.

The first step to any reliability improvement program is to define what data or information will be required to drive defect elimination.  In the previous posts, the following topics were discussed;

All of the topics discussed what data is required and how to structure the data to implement a reliability engineering program or defect elimination process.   Understanding the what, when and why set up and is required to setup a reliability engineering […]

Understanding ISO 14224: You Guide to Sustainable Defect Elimination

Capture The Right Failure Data to Power Your Defect Elimination Activities

In the petroleum, natural gas and petrochemical industries, great attention is being paid to safety, reliability, and maintainability of equipment.  This is true in any industry and as such the learnings and information found within ISO 14224 can be applied to any industry.

While ISO 14224 was developed for the Petroleum, Natural Gas and Petrochemical industries, the same process can and should be applied in any organization.   When implemented, the right data can be gathered to not only eliminate defects from […]
