Optimum Maintenance Intervals in RCM++
Preventive maintenance can yield significant cost
benefits by increasing the availability of a system and
reducing the total maintenance costs. The question of
how often the task should be performed, however, is
important to raise. If the preventive maintenance
interval is too short, then the maintenance costs
associated with preventive maintenance can be too high.
If, on the other hand, the interval is too long, then
the costs associated with corrective maintenance can be
too high. RCM++
provides calculations to help determine the optimum
maintenance interval, based on the probability of
occurrence of a failure event and the costs of
performing different types of maintenance. In this
article we will provide the theory behind this utility
and give an example that illustrates its application in
the software.

Reliability Basics |
Determining Significant Effects in 2k Designs with a
Single Replicate
Design of Experiments (DOE) is a systematic approach to
experimentation that is used to investigate how various
inputs (or factors) affect an output (or response) of
interest. One of the useful results of the statistical
analysis performed in a DOE is whether an investigated factor's
effect on the response is
significant. In order to do that, replicated runs are
required. That means that all the combinations of factor
levels (treatments) should be performed more than once.
However, in many experiments running replicates of an experiment is not
feasible due to a lack of time or resources. In this article we will present three methodologies
that can be applied in the case of 2k
designs (where each factor has only two levels) to allow
us to test for the significance of an effect without replicated runs.

Congratulations to
the 2010 ARS
Excellent Presentation Award Winners!
- Each year, engineers strive to present at
one of the Applied Reliability
Symposium (ARS) events held five times a year at locations around the world. One of the coveted goals for many presenters is achieving an
excellent presentation award. The winners are selected based on votes cast by the symposium attendees.
Here are the winners from recent events in Europe and North America : Berlin, Germany
- Martin Shaw (Gold Award - €500) from
Reliability Solutions for his presentation, LCD TV Reliability Testing: An
Effective Approach
- Horst Lewitschnig (Silver Award - €375) from Infineon
Technologies Austria AG for his presentation, Stress Interaction Model
- David
J. Hartshorne (Bronze Award - €250) from The New Science of Fixing Things Ltd.
for his presentation, Identify and Fix Reliability Problems Missed by FMEA &
Validation Testing Before Shipping
Reno, Nevada - United States
- Harland
MacKenzie (Gold Award - $1000) from Dana Thermal Products for his presentation,
The Life-Stress Slope: The Key to Accelerated Life Testing
- Romney B. Duffey
(Silver Award - $750) from Atomic Energy of Canada for his presentation, High
Reliability and Systemic Risk: Predicting Rare Events and Failures in Modern
Technological Systems
- Peder Andersson (Bronze Award - $500) from Tetra
Pak for his presentation, The Reliability Sleuth – A Proposal for a
Troubleshooting Process

RGA 7.5
Released - The ReliaSoft software
developers occasionally find themselves with a
long wish list of feature enhancements, thanks
to your valuable feedback and our own internal
research. While we make every effort to include
the majority of features within the initial
distribution of a major version release,
occasionally extra time is needed to achieve
completion. RGA 7.5 now contains an abundance
of new items we have been wanting to share.
Any engineer currently using RGA 7 is welcome to
review the list of additions
and
download the latest
service release for free. Please visit the
following locations:
