If your organization is like most using automation for productivity, then overall equipment effectiveness (OEE) is most likely being used as a key metric in determining where improvement efforts should be focused.
The odds of picking the first place winner in a horse race are slim. The odds of picking the first, second and third place winners are even less favorable, but when it happens, the trifecta payday is big!
On Tuesday (Oct. 7), the Royal Swedish Academy of Sciences awarded the 2014 Nobel Prize in Physics to three researchers whose work contributed to the development of a radically more efficient form of lighting known as light-emitting diodes, or LEDs.
Machine condition monitoring requires a proper foundation from understanding and aligning criticality and failure mode analysis. Sadly, for most plants, condition monitoring consists of multiple technologies that are cobbled together in an attempt to enhance machine reliability.

The short reason is because complex systems can have more requirements which, in turn, increase the number of failure points. And each requirement can have multiple prerequisites. An asset management system has three main areas needing ongoing attention: software/data, process/procedure and roles/responsibility. Advanced processes have the most prerequisites. Weakness in any one area or supporting variable can cause system failure.
Reliability has become such an integral expectation in our society that it is difficult to imagine a world where things do not work as expected. The first use of the word reliability was by poet Samuel Taylor Coleridge, who bestowed the word on his friend, the poet Robert Southey, to praise his steadfastness. From this seemingly insignificant usage of the term, reliability has grown enormously to a broadly accepted, if not entirely understood, property that everyone expects for a wide range of situations. Online searches for reliability and related terms result in thousands of references in papers and manuscripts and literally millions of hits on the Internet.
Torsion fatigue failures occur more frequently than we realize. As a teacher of failure mode identification, it is common to have one or more individuals in every class bring an unusual failure to class that, upon examination, is torsional fatigue. Depending on the particular industry, torsional fatigue is involved in 10 to 25 percent of rotating equipment failures.
Crossrail is a high frequency, rail link being built to serve London and South East England. Twin 21km tunnels (42km combined) are being bored across London to link the surface sections of Crossrail and the 10 new stations being constructed along the route, 35km of which have already been excavated by eight tunnel boring machines.
