Accendo Weekly Update #447 May 26, 2024
Applied Reliability Analysis
A New Course by Steven Wachs on Using Weibull++
This is a quiet, well, not so quiet, new course announcement. The 32-hour course is on-demand, online, and self-paced and covers the common reliability analysis techniques many reliability professionals perform, such as life data regression analysis, estimating reliability metrics, analyzing field data, test planning, accelerated life testing, and more.
We're still working on setting up the options for group purchases or buying individual modules. We expect to have those options available later in the week.
As with all of Steven's courses, there is a participant guide, textbook, and data files for examples and exercises, plus instructor support via email or phone. If you have any questions about the course - let us know.

Announcements & Reminders
Seems organizations are working on hiring again, as my informal observation of requests for candidates indicates. Just this week I've learned about 6 openings for reliability engineers. From experienced technicians, to very experienced engineers. One is located in Silicon Valley, the other is in Wisconsin. If you would like to know a little more about these opportunities, let me know.
Stay safe, stay flexible, and stay resilient.
Cheers,
Fred
PS: seems an active time of year for call for papers.

Fundamentals of Process Capability
Calculating and interpreting the process capability ratios is the easy part. Getting valid results takes more work and thinking. Knowing that the process is capable is only one use of this information. We should also use the information contained in these ratios to inform product design tolerance.
Let’s explore the steps necessary to obtain valid and valuable process capability ratios. Then, let’s examine a few ways to use this information to effectively improve our processes and designs.
Using Monte Carlo Simulation to Make Hard Reliability Analysis Easy
Sometimes the equations we need to model reliability are just so complicated that we simply avoid them, or use other equations that are simpler but model the wrong thing (see some of my earlier webinars!). But it doesn’t have to be this way. Monte Carlo simulation is so simple that anyone who has access to Microsoft Excel can use it. What this means is that we don’t need to use complicated equations (like those use to model things like switching systems) and instead can use Microsoft Excel to help us get approximate (but really accurate) answers.?

Using FMEA (or functional) Block Diagrams to Understand your Item
Scheduled for May 28, 2024, at 8 am?US Pacific time.
领英推荐
Speaker: Chris Jackson
Many engineers rush to design or build something that we think is ‘awesome’ or at least ‘proves a concept.’ But this often means we build something that we like (not necessarily what our users like) or doesn’t work (because we didn’t realize that have sensitive electronic components near hot exhaust manifolds would be a problem). This is where taking a breath and understanding our product before we build the wrong thing fast can really helpful. A FMEA or functional block diagram can really help us visualize what different parts of our system do, and how they interact. They also help us identify the basic, interface and additional functions that separate an ‘average’ product from an ‘industry leading’ product. If this is something you think you or your team can benefit from, join us for this webinar.

Fundamentals of Hypothesis Testing
Scheduled for June 11, 2024, at 9 am?US Pacific time.
Speaker: Fred Schenkelberg
Let’s make a comparison. Let’s check our product’s key characteristics against specifications, compare vendor life data, or compare the newest design changes to prior performance. We can and should do comparisons well using the appropriate statistical approach. Let’s examine a handful of parametric and non-parametric comparison tools, including various hypothesis tests. Plus how to best use these tools and when to set them aside and explore another approach. Statistics is a part of what a reliability professional does; thus, we all should know the range, power, and applicability of the methods available. Let’s explore how to make comparisons well.

What Price Kaplan-Meier Reliability?
The Kaplan-Meier estimator is the maximum likelihood, nonparametric reliability estimator for censored, grouped lifetime data. It’s traditional. It’s in statistical software. Greenwood’s variance formula is well known. Could Kaplan-Meier be improved: smaller variance, better actuarial forecasts, seasonality, separate cohort variability from reliability? ? ...[Read more…]
