Formula for Mean Time Between Failure (MTBF)
Which formula do you use to calculate MTBF?
a) MTBF = operating time / no. of failures in between,
where operating time = current date - date of first production. Of course, running hour is better if available.
b) MTBF = (start date of last failure - start date of first failure)/(No. of failures - 1). This leaves out the running time before the first failure and final failure from the calculation. Any advantage in doing this?

Electric Motor Repair: Research Project on Soft Foot
An iPresentation Tutorial by Howard Penrose, PhD, CMRP, Success by Design Reliability Services
In this 14 minute iPresentation, we are going to cover a research project that was independently performed on the mechanical impact of electric motor rewind. A fair amount of research had been performed on the impacts of thermal stripping on motor cores including work by General Electric, the Canadian Electrical Association and the Electrical Apparatus Association over the years. However, in each case, representatives from the motor repair industry had objected to an evaluation of the mechanical aspects of the system. Due to a number of instances identified through field service work, an independent research project was performed by Dreisilker Electric Motors Research and several partners.
This iPresentation is a summary of the 1997 IEEE EIC conference paper on the impact of thermal stripping on electric motor reliability.

New Surge Testing Technique for High Inductance Equipment
An iPresentation Tutorial by George Frey, Baker Instrument Co.
This 8 minute iPresentation tutorial covers a new technique that has been developed to provide valuable information on DC or direct current windings. The circuitry behind the surge test has been improved to provide substantially better ring patterns for these types of hard to test windings due to their turn characteristics. A much greater degree of sensitivity is also found in the L-L EAR or Line-Line Error Area Ratio calculations. With these two data points DC motor problems can be identified and recorded for trending and troubleshooting.

How do you assure the “Crime Scene” is preserved for Root Cause Failures Analysis?
An iPresentation Tutorial by Ken Bass, CMRP, Field Manager
Much has been written about the magnitude of Root Cause Failure Analysis (RCFA) and the importance of preserving the evidence at the beginning of the investigation. Many have compared preserving the evidence as the same as preserving “the Crime Scene”. For the police, preserving the Crime Scene begins when the call comes in and officers are quickly dispatched to string the yellow tape. But how do you confirm that the Crime Scene is preserved at your plant? In this 7 minute iPresentation, Ken Bass, reviews the key components necessary to any RCFA program.

What is the actual added value of maintenance?
by Mark Haarman and Remco Jonker
That is a frequently heard question in boardrooms the world over. Even though maintenance is often critically important, few maintenance managers are able to answer the question convincingly. Especially when they are asked to express the benefits in terms of economic value added or shareholder value - the language being spoken in boardrooms.
For this reason Mainnovation developed the Value Driven Maintenance (VDM) methodology, which is implemented in leading maintenance organizations like DSM, Smurfit Kappa, Sara Lee, GlaxoSmithKline, Akzo Nobel and Volvo Cars. More…

Paul Barringer’s Reliability Problem Of The Month Workshop at IMC-2007
December 5, 2007
Daytona Beach Florida
You are invited - to Paul Barringer’s Problem of the Month - A facilitated lesson in reliability.
Noted Reliability Expert Paul Barringer and Reliabilityweb.com Publisher, Terrence O’Hanlon are joining forces to bring you practical, hand’s-on reliability engineering problems and solutions based on Mr. Barringer’s long running web based challenges.
This is a Beta Launch and you are invited to participate as part of IMC-2007. All we ask is that you actively participate by using your best efforts to understand the 4 problems and apply the solutions being taught.
The first three problems are from http://www.barringer1.com and the 4th problem will be derived from one lucky student’s actual data.
Note: Although some people are intimidated by the engineering behind these problems and solutions, Paul Barringer specializes in translating the tools and techniques into useable skills for maintenance and reliability professionals - even if you have never used a slide rule.
