Dear Larry
Thank you for your data request for breast implant data and apologies for the delay in responding. The data available is:
My colleagues have been copied into this email to show your request has been actioned. I hope this is helpful. [Read more…]
In the last edition of R for Engineering, we learned how to draw small multiple plots in R and harness the power of comparison. We went from a busy graph to being able to use ggplot’s faceting functions to create a small multiples plot. If you need a recap, here’s a link to the last edition.
That is to say, nature’s laws are causal; they reveal themselves by comparison and difference, and they operate at every multi-variate space-time point.
– Edward Tufte
Small multiples have many uses in engineering, but the one I personally use them the most for is characterization and diagnosis. In my line of work, which is quality engineering, the ability to diagnose problems in physical systems (both product and machine/process-related) is a critical skill, and I will go as far as to say that diagnosing problems is a critical skill in any engineering discipline.

Risk management is an objective-focused concept. Risk professionals must, therefore, be a catalyst, an advocate, and trusted friend for driving superior organisational performance.
They must walk alongside executives, managers and staff to achieve organisational objectives by making better decisions under uncertainty, risk, and opportunities.

To increase reliability, you need to decrease the chances of failure occurring. Each chance of failure creates risk. Operating risk can be mitigated and managed by meeting all 15 Precision Maintenance excellence targets.
This list of precision maintenance excellence targets is how to ensure component parts, and the equipment they are in, always operate with optimal reliability. Each requirement must be met to the highest standard. By doing this your equipment and machinery are operating with the least microstructure stress possible and getting utmost reliability.

Did you know that early FMEA standards did not include recommendations to reduce risk? They limited the analysis to the technical risk, without making specific recommendations. The first time I am aware of that an FMEA standard added a column called “Recommended Actions” was in 1993. Thankfully, it is common practice today to include Recommended Actions in FMEAs.
But what makes for excellent Recommended Actions and what is their role in an FMEA? We’ll begin with the fundamentals.
Here’s a common situation that most of us have experienced in our careers or education:
You’re working on a project with a tight deadline, the task is do-able, but difficult. Everyone has their specific tasks assigned, and the whole team is working together on a final document to turn in. Your section is the financial analysis portion of the project.

While evaluating impact of a toxic release, you may be interested in how the concentration of the toxicant increases in a room and its impact on indoor personnel. For example, if there is a H2S release in the plant and you want to estimate the increase in concentration in a nearby office building.
I want to share a simple model to estimate indoor concentrations following an outdoor toxic release. [Read more…]
Opinion-based data is the foundation of qualitative assessments. Qualitative assessments are used in various applications, including asset management, risk management, human reliability analysis, and customer surveys. The usefulness of any qualitative assessment is a function of design, analysis, and administration. This article summarizes a review of ten risk matrices performed by facility owners or their consultants. [Read more…]
In this week’s edition, I introduce you to the concept of small multiples, and, more importantly, how to make them in R. This is one of those really low effort-super high return kind of features of R that can make you look like a rock star of data visualization. So, without further ado, let’s jump right into it!

New superconducting magnet breaks magnetic field strength records, paving the way for practical, commercial, carbon-free power fusion energy. MIT and U.S. startup company Commonwealth Fusion Systems (CFS) led the project. This test paves the way for a demonstration device to show a plasma can be created and contained that generates more energy than it consumes. The demonstration device is expected to be completed in 2025. The hope is that in the future there will be thousands of fusion plants powering clean electric grids around the world helping to save the planet.
Abstract: Many companies struggle with constant plant and equipment problems despite doing the very best they know how to keep their plant and machinery reliable. Their real problem, which they cannot see for themselves, is that what is done in the company is completely wrong for creating highly reliable production equipment. If you cannot “see” how reliability is destroyed in your business, then you are doomed to suffer poor reliability and low uptime forevermore.

In the early 1700’s, English mathematician and Presbyterian minister Thomas Bayes derived the eponymous mathematical theorem that allows us to calculate the probability of an event occurring based on prior knowledge of conditions that might be related to the event.

Earlier I had written about the use of RFID for tracking hazardous substances. One of the readers, Sujith, wrote to me that RFID can be a ignition source and thus pose a potential for fire/explosion.

In today’s competitive business environment, reliable equipment operation is crucial for uninterrupted operations and increased productivity. On the other hand, saving on maintenance costs can be a perilous path to tread.
Maintaining a balance between the two factors can have far-reaching effects, potentially even raising maintenance costs. The solution lies in optimizing equipment reliability, making it the bedrock of maintenance efforts.
It may be difficult to accelerate double-digit percentage cost reductions in some industries, such as pharmaceuticals and nuclear. Nonetheless, the primary focus should be on improving equipment reliability, which could lead to lower maintenance costs. [Read more…]
