Analysis of Accelerated Life Tests with Competing Failure Modes
Accelerated tests that yield a mix of failure modes have long troubled
reliability analysts. Oftentimes when dealing with accelerated test
data, all failures, regardless of their cause or which part of the
product they affected, are lumped under one category - failures. This
approach does not provide a way to distinguish between failure modes and
treat them separately. Also, lumping all failure types together might
lead to the violation of a common accelerated life testing analysis
assumption, the constant shape parameter. This article presents a simple
approach to analyze accelerated life tests with competing failure modes
using ALTA 6,
Weibull++ and
BlockSim.To read

What Would Deming Do?
In this article, we examine principles set forth by Dr. W. Edwards
Deming, a pioneer in using statistical methodologies for reliability and
quality improvement. Known for being the father of the Japanese post-war
industrial revival and a leading quality guru in the United States,
Deming helped Japanese industrial leaders and engineers transform world
perception of Japan from a cheap manufacturer to a world class
manufacturer producing innovative, high-quality products. In 1960, he
was awarded a medal by the Japanese Emperor for his services. Deming
returned to the U.S. and embarked on a mission to teach his philosophy
and statistical techniques for quality to American manufacturers. In
1982, Deming published his book "Out of the Crisis," in which he
presented his 14 Points. His philosophy is an important framework for
implementing reliability, quality and productivity improvements. Even in
the new age, there is still a lot to learn from these 14 points.

ESREL
2006
- ReliaSoft will be present at the 2006 European Safety and
Reliability Association Conference on September 18-22, 2006
in Estoril, Portugal. This year's topic will focus on Safety and
Reliability for Managing Risk. The purpose of the conference is
to present and discuss modern innovations, traditional methods
and relevant applications. Goals include improving the design
and operation of products, processes, equipment and
installations from a safety point of view, while taking into
account the realistic constraints on the available physical and
economical resources. Societal factors influencing the use of
risk assessment and risk management methods will also be
addressed.
ReliaSoft scientists will be available for one-on-one
interactions at our booth in the exhibitor area. We hope to
see you there! More information is available at:

Coming
soon: Weibull++ 7 DE (Developer Edition) - Scheduled
for sometime in the Fall, this major version upgrade will be the
newest release to our Reliability suite. You will soon be able
to create your very own custom designed applications with the
functionality of Weibull++ 7. This will allow you to automate
data analysis in applications such as Excel or Access and/or
create applications that link to corporate data centers and
perform automated analyses. Weibull++ 7 DE provides access to
ReliaSoft's Weibull++ engines and interfaces through API calls.
We will keep you posted as we get closer to the product's
release. |

Lambda
Predict Training Course - A new training course
has been added for engineers interested in Standards Based
Reliability Prediction analysis and ReliaSoft's corresponding
software, Lambda Predict. The first class will be held in
Tucson, AZ November 30 December 1, 2006. True to form,
ReliaSoft's
RS 490 will provide hands-on learning as we explore topics
such as BOM importation, creating system hierarchies, analyzing
complex systems, viewing results and creating reports.
Reliability prediction standards covered during this two-day
course include MIL-HDBK-217, Bellcore, NSWC, RDF 2000 and China
299, with more focus on the first three standards. |
