by Mr. Chet Haibel, M.S.E.E.

This class starts with foundational concepts to develop an understanding of reliability in the three parts of the bathtub curve. Reliability mathematics are explored using the exponential distribution and constant failure rate as the first example. Examples are sprinkled throughout to help reinforce concepts. The first day ends by illustrating the advantages in prototype quantity and test time of using HALT to discover relevant failure modes and to do a comparison demonstration of reliability for new product release.

The second day generalizes concepts and mathematics developed the first day into the Weibull distribution and non-constant failure rate. The vertical scale on a Weibull graph is de-mystified as are censored and interval testing. Applications of Weibull Analysis for minimal testing using WeiBayes and zero-failure test strategies to save time and money are presented. Field failure prediction and accelerated testing using Weibull Analysis culminate the two days.

WHO SHOULD ATTEND

This course is intended primarily for Engineers and Managers in New Product Development, Reliability, and Quality.

Why Should My Company Develop a Basic Understanding of Reliability?
A new Paper
by Chet Haibel, M.S., CRE, CQE
When a company wants to move to the next level in reliability, for example when the Reliability Engineers want to institute HALT, Cycle Testing, Failure Analysis, Design for Reliability Guidelines, HASS, and such, they need the support of New Product Development engineers, project managers, supplier managers, material engineers, etc. After all, these are the folk who fear their schedule and budget may be adversely impacted. They need to understand that properly applied reliability techniques shorten schedules and save money. Everyone must be rowing the boat in the same direction. This starts with a common understanding of terms: the three kinds of failures, how each is caused, and therefore how each is discovered, corrected, and prevented. The role of stress in reliability is another key concept everyone in the company should understand.
