Advanced Weibull Workshop

Instructors: Dr. Robert B. Abernethy, Wes Fulton, Paul Barringer

RMS (Reliability-Maintainability-Safety-Supportability) engineering is emerging as the newest discipline in product development due to new credible, accurate, quantitative methods. Weibull Analysis and Crow-AMSAA are foremost among these new tools. New and advanced Weibull techniques are a significant improvement over the original Weibull approach. They yield useful results even with extremely small samples and with data that has deficiencies. Special methods developed for these data problems, such as Weibayes, are presented with actual case studies. Inspection data will be treated with with interval, probit and MLE interval methods.

The Advanced Workshop will familiarize participants with the latest techniques and advanced applications of in WinSMITH™ Weibull for risk forecasts with renewal and optimal component replacement will be illustrated with case studies. Students are fully qualified to conduct Weibull Analysis at workshop completion. Students May Bring Their Own Data for Analysis (laptop required).

Benefits of Attending
By attending this workshop, you will be able to use Weibull's unique capabilities to:

Analyze design, development, production, and service failures
Model product lifetime and reliability
Evaluate supportability & maintainability plans including optimal parts replacement
Analyze different types of inspection data
Reduce test substantiation, time and costs

Who Should Attend

Engineers responsible for reliability, safety, supportability, maintainability, materials, warranties, life cycle cost, design, structures, instrumentation and logistics will find these Weibull techniques extremely useful.

Continuing Education Units

Upon completion of the course, participants will be eligible to receive 1.2 Continuing Education Units (CEUs).

Text & Software Included

Each attendee will receive the entire SuperSMITH package, a $960 value. SuperSMITH contains: the New Weibull Handbook, written by Dr. Robert B. Abernethy, along with classwork, answers, and references; the latest WinSMITH Weibull, WinSMITH Visual and YBATH software which are used in the workshop; and the Play-Time Tutorial Software Workbook. This state-of-the art, Windows software includes Weibull, Extreme Value, Normal & Log Normal Analysis and allows the student much more time for actual hands-on PC experience, interpreting data of all types.

All students must bring a laptop computer.
