What tools does ReliaSoft offer to help engineers design
reliability tests?
ReliaSoft offers several tools
to help engineers design effective reliability tests:
-
Weibull++ and
ALTA include the Design of Reliability Testing (DRT)
utility. This utility allows you to determine the required
number of units and/or test time required to demonstrate a
certain reliability result. It is a useful tool when you
need to evaluate the number of units, the test time required
under a certain testing scenario or the reliability and
confidence that can be demonstrated if such a scenario were
actually implemented. The Reliability HotWire
article entitled
Design of Reliability Tests (Issue 24) shows how to use
the utility. While the article was written for Weibull++
6, the material is still valid in Weibull++ 7 and
ALTA.
-
Weibull++
and ALTA also include the SimuMatic utility. This
utility allows you to perform a large number of reliability
analyses on data sets that have been created using Monte
Carlo simulation. This can help you to a) better understand
life data analysis concepts, b) experiment with the
influences of sample sizes and censoring schemes on analysis
methods, c) construct simulation-based confidence bounds, d)
better understand the concepts behind confidence bounds and
e) design reliability tests.
-
ALTA
includes the Accelerated
Life Test Plans utility, which assists you in designing an
accelerated life test that will yield the closest possible
estimate of product life at the percentile and the use
stress level you specify. You can design plans for one or
two stresses. The Reliability Edge article entitled "Accelerated
Life Test Plans" (Volume 8, Issue 1) demonstrates the
use of this utility.
-
DOE++ is
designed to facilitate traditional Design of Experiments
(DOE) techniques for studying the factors that may affect a
product or process in order to identify significant factors
and optimize designs.
ReliaSoft also offers two
courses that provide information about reliability tests.
-
The
RS 401 Reliability and Life Data Analysis course
provides a comprehensive treatment of the subject of life
data analysis as it applies to reliability engineering.
Reliability test design is one of the many topics covered.
-
The
RS 588 DOE: Experiment Design and Analysis course begins
with DOE fundamentals and continues with advanced concepts,
principles and requirements. It has both theoretical and
hands-on sections.
In addition, the following
publications include information that you can use:
-
The
Test Design topic in ReliaSoft's Life Data Analysis
Reference provides an overview of test design theory.
-
The
Cumulative Binomial for Test Design and Analysis
Reliability Edge article presents a summary of the
techniques available to use the cumulative binomial
distribution to assist in the design of effective
reliability demonstration tests and also to determine the
reliability that has been demonstrated in a test with few or
no failures.
-
The
Using OC Curves in Design of Reliability Tests
Reliability HotWire article describes how to use
operating characteristic curves when designing reliability
tests.
-
Several of ReliaSoft's team
members have published papers and/or given presentations
that talk about reliability tests. For a list, refer to

What discounts are available for ReliaSoft's training seminars?
When you are registering for
training seminars with ReliaSoft, bear in mind that there are
several money-saving opportunities that you may be able to take
advantage of. These include:
-
Combined
Session Discounts: Whenever possible, ReliaSoft offers
multiple training courses in the same location over the span
of a week (e.g. RS 401, 402 and 403). This helps
minimize travel costs and allows you to take advantage of
the combined session discounts available for these events.
-
Group
Discount: ReliaSoft offers a 10% discount when three or
more attendees from the same corporate entity and the same
location register together for an event.
-
Software
Purchase Discounts ("Bundles"): ReliaSoft offers bundled
pricing options that provide discounts when you purchase
software in conjunction with training seminars; for example,
when you purchase Xfmea and register for RS 470 or purchase
RENO and register for RS 525. Specific discounts are posted
on the Web at
http://www.ReliaSoft.com/bundles.htm.
-
Repeat
Registration Discount: ReliaSoft offers a 50% discount
when you register again for any training course you have
previously attended.
