Developmental Testing
with Corrective Actions Implemented During the Test and Delayed Fixes
Traditional
reliability growth tracking and reliability growth projection models
address reliability growth based on failure modes that appeared during
the test. With the tracking model, all corrective actions are implemented
during the test (test-fix-test). For the projection model, all corrective
actions are delayed until the end of the test (test-find-test). However,
for developmental testing programs, it is more common to implement some
corrective actions during the test and some delayed fixes at the end of
the test (test-fix-find-test). In addition, reliability growth assessments
for the test-fix-find-test strategy are not provided with the widely used
traditional models. This article presents the use of an extended
reliability growth model for analyzing test-fix-find-test data in
RGA 6 and is based on the paper "An
Extended Reliability Growth Model For Managing And Accessing Corrective
Actions" presented by Dr. Larry Crow at the 2004 RAMS.To

Predicting Warranty Returns
Accurate predictions about the quantity of products that will be returned
under warranty can provide huge benefits to manufacturing organizations. Among
other advantages, better warranty data analysis allows an organization to make
the most efficient allocation of resources to warranty services provision.
Likewise, they allow the manufacturer to anticipate customer support needs and
take the necessary steps to insure customer satisfaction with the warranty
process. Warranty data analysis can also provide a valuable early-warning
signal to the manufacturer when there is a serious product quality problem in
the field, which gives the organization time to mobilize its resources to meet
the challenge before serious financial, legal or other problems occur. This
article presents the process on how warranty analysis can be accomplished
in Weibull++ 6.To read more, see

| From the Edge |
In addition to the
monthly Reliability HotWire, ReliaSoft publishes
Reliability
Edge, a printed newsletter that includes articles and information
related to the field of reliability engineering. An article of interest in
the current edition:
- Graphical
Comparison of Sets of Repair Data - As a population of repairable
systems ages, the systems accumulate repairs and repair costs. The
population Mean Cumulative Function (MCF) for the
number or "cost" of repairs as a function of population age yields
much useful information. This article and Nelson (2003) show how to
estimate and graphically compare the MCFs of two samples of systems.
This comparison also applies to recurrence data on recurrent disease
episodes, sociological and demographic applications such as
childbirth, simulation of production processes and other recurrent
events. See the complete article at:
http://www.ReliaSoft.com/newsletter/v4i2/graphical.htm.
