Weibull-Log Normal Analysis Workshop

RMS (Reliability-Maintainability-Safety-Supportability) engineering is emerging as the newest discipline in product development due to new credible, accurate, quantitative methods. Weibull Analysis is foremost among these new tools. New and advanced Weibull techniques are a significant improvement over the original Weibull approach. This workshop, originally developed by Dr. Bob Abernethy, presents special methods developed for these data problems, such as Weibayes, with actual case studies in addition to the latest techniques in SuperSMITH® Weibull for risk forecasts with renewal and optimal component replacement. Class work is used to reinforce key concepts, lectures are based on actual case studies, and personal computers and hands-on experiments are used to analyze dozens of Weibull & Log Normal problems. Students will be fully capable of performing basic and advanced RMS Engineering analysis with their own software on completion of the workshop.

Attendees will receive the entire SuperSMITH® package - a complete self-study course and combined software package containing: SuperSMITH® Weibull, SuperSMITH® Visual, The New Weibull Handbook® - 5th Edition and the PlayTIMETM Tutorial Booklet. A $960 value!

***Attendee must bring laptop for this course.***

Bonus Introductory Course Included
To accelerate your learning, you may want to complete the SAE On Demand Course, PD530946ON - Introduction to Weibull Solution Methods, prior to the Workshop. Your registration will give you online access to this highly recommended, 75-minute overview of Weibull Analysis approximately 10 days in advance of the course start date, access ending the last day of class.

What Will You Learn

By attending this seminar, you will be able to:
  • Analyze design, development, production, and service failures
  • Model product lifetime and reliability
  • Evaluate calibration and maintainability plans
  • Analyze inspection data
  • Reduce test substantiation, time and costs

Is This Course For You

An engineering undergraduate degree in any discipline would be beneficial. Engineers responsible for reliability, safety, supportability, maintainability, materials, warranties, life cycle cost, design, structures, instrumentation and logistics will find these Weibull techniques extremely useful.
