Chris and Fred discuss Markov Chain modeling. Where we model transitioning from one state to another – which is often used for availability. How and when do I use it? Does it work in today’s reliability applications? Listen here to learn more.
Key PointsJoin Chris and Fred as they discuss Markov Chain modeling – which is often taught in universities but may not be as practically useful. A Markov Chain is a series of ‘states’ that could (for example) represent a system fully functional (state 1), degraded (state 2) and failed (state 3). You can have as many states as you like. Then there are transition rates between each state – which must remain constant. This starts to become useful when you want to model failure AND things like repair – where you transition from a failed state to a functional state. Does this work?
Topics include:
- How are Reliability Block Diagrams (RBDs) and fault trees different? These traditional modeling mechanisms tend to focus on failure – and not going back to a functional state, degraded state, or any other state you define.
- … but Markov Chains are ‘memoryless’ or ‘ageless.’ This means that the transition rates are constant. They don’t change with respect to time – or system age. Nor do they change based on how long your system has been in each state.
- So Markov Chains are primarily used for steady-state availability. Trying to work out the likely long term probabilities of your system being in any one of the states you defined.
- Are they like Petri nets? No. Petri nets may look like Markov Chains, but instead, the model is based on tokens moving through the chain to understand system behavior.
- Other ways? Try Agent-Based Models. Relatively simple rules can then treat your system as an ‘agent’ … and then you can control the way your systems behave in much greater detail.
- What about Markov Chain Monte Carlo (MCMC) simulations? If you have heard of this – don’t worry! MCMC is a simulation technique based IN PART on Markov chains to help create a representative sample of random variable values from a given function (like a probability density function). This is useful for solving some complex calculations – including reliability engineering complex calculations – but is not what we are talking about here!

Key PointsJoin Adam and Fred as they discuss how to use the product’s reliability goal to drive the test and development program.
Topics include:- Planning testing such as vibration or temperature without a “why?” can lead to wasted effort
- A reliability program phase should always be guided by the “I” word “Intent.”

0 min - The Reliability Engineering Management TutorialThe Reliability Engineering Management TutorialAbstract
Chris and Fred discuss the Reliability Management Tutorial that Chris and Carl Carlson (another Accendo contributor) will be delivering at the Reliability and Maintainability Symposium (RAMS) in Palm Springs later this month. This tutorial can contribute to you getting a certificate as well if you are attending. Like to learn more? Listen here.
Key PointsJoin Chris and Fred as they discuss the Reliability Management Tutorial that Chris and Carl Carlson will be contributing at this years Reliability and Maintainability Symposium (RAMS). This is the famous tutorial that used to be delivered by Fred – who is now allergic to travel! But going back to reliability management – it is all well and good to know what an accelerated life test is, or how to do Weibull analysis – but when do you need to do these things? How much should you spend on activities like this? Where do we start? Is there a structure? Well yes there is, and this tutorial covers many of these things.
Topics include:
- The tutorial talks about the five steps to making a reliability plan. If you are struggling to work out what the ‘next steps’ are and how this relates to your business and customers, this tutorial is for you.
- Reliability is not just about modelling and analysis. It is all about how reliability helps your business. And the tutorial helps you frame a structure that helps you work out when you need to model, what you need to analyze, and how these things add value. In fact, the first things you do should be the more ‘basic’ activities – and it is only once your organization is strategically mature that you have a need to undertake detailed modelling and analysis.
- You must know the problems you are solving. You need to talk the management language. And more often than not – this must be about money. Don’t misunderstand … this is about customers too! Because the happiest customers are the ones that are willing to give you money for your product. So you make your customers happy, your organization is happy.
- If you hired smart people – all you need to do is let them do their job. Management is not about doing things for your subordinates. It is about maximizing their skill sets. Giving them freedom to do their job. And reap the rewards.

0 min - 3 Questions to Get Started with HALT Planning3 Questions to Get Started with HALT PlanningAbstract
Kirk and Fred discussing a listener’s question on how to get started with HALT (Highly Accelerated Limit Test).
Key PointsJoin Kirk and Fred as they discuss various issues around applying HALT to a new product.
Topics include:- Assessments of how the product may be divided between mechanical assemblies (motors, gears, bearings) and electronics control board or card cage to apply the highest level of stresses and not exceeding the fundamental limit of the technology.
- Determining the subsystems that may already be available to test before the total BOM is ready to build a full systems.
- Almost any prediction without verified empirical correlation with the models used for prediction is misleading and most traditional reliability prediction methods lack these correlations.
