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 more, see

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!

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. |
