Analysis and Modeling of Grouped
and Opportunistic Preventive Maintenance
When planning preventive maintenance strategies, considerations
of the overall benefit for the whole system should supersede the
optimum plan for each component separately. Maintenance plans should
be addressed in a holistic way to optimize the cost of ownership
of the system. For example, sometimes it is less expensive and more
convenient to perform preventive maintenance on a component in a
system when performing a repair action on another component in the
system rather than at the optimum time for performing the preventive
maintenance for that component. A repairable system reliability
and availability modeling and simulation tool, such as
BlockSim
7, can help model your system and assess different maintenance
strategies to determine what will be best for the overall system.
This article discusses how to model grouped and opportunistic maintenance
strategies in BlockSim.To read more, see

Reliability Growth Analysis
with Missing or Erroneous Data
Most of the reliability growth models used for estimating
and tracking reliability growth based on test data assume that the
data represents all actual system failure times (complete data)
consistent with a uniform definition of failure. In practice, unfortunately,
things do not always work out this way. There might be cases in
which training issues, oversight, biases, misreporting, human error,
technical difficulties, loss of data, etc. might render a portion
of the data erroneous or completely missing. Without applying "corrections"
to the way the data set is handled and the way the models and their
parameters are derived, "standard" analysis may result in distorted
estimates of the growth rate and actual system reliability. This
article discusses a practical reliability growth estimation and
analysis procedure to treat data that contains anomalies over an
interval of the test period. ReliaSoft's
RGA 6 software is
used to perform the analysis.

IIE
awards ReliaSoft Scientist – Dr. Harry Guo, ReliaSoft's Director
of Theoretical Development, and his co-authors
received the “Best Paper Award of Quality Control and
Reliability” at the Industrial Engineering Research
Conference, Nashville, Tennessee, May 19-23, 2007, for the
paper titled "Multiscale Monitoring of Autocorrelated Processes
Using Wavelets." This paper was chosen to be the best
amongst 66 others, written by professors, engineers and
some very well-known names in Reliability and Quality Engineering,
and it thus represents a great achievement. ReliaSoft
is proud to have the best Theoretical and Research Department
in the business. |

ARS Asia Pacific - Here is a great opportunity
to mingle with the growing ranks of reliability and quality
professionals in the Asia Pacific arena. If you have not
attended this event in the past, then we encourage you to see
for yourself why it has become such a popular and
important annual event. The International Applied
Reliability Symposium - Asia Pacific will be held at the
Orchard Hotel Singapore in Singapore on October
25 - 26, 2007. The Symposium will focus on "sharing applications,
success stories and lessons learned in reliability and maintainability
engineering." Fact sheets and registration
information can be obtained

Design for Reliability (DFR)
Training
- It's not too late to sign up for a newly released
Design for Reliability (DFR) training course.
This class brings together
the entire set of methods and tools that support product
and process design (during the Product Development Cycle)
to ensure customer expectations for reliability are fully
met. ReliaSoft's RS 560 - Introduction to Design
for Reliability training course provides an introduction
to individual DFR methods, the proper use of relevant software
tools, key elements of successful DFR programs, common pitfalls
to avoid and other useful topics. The course will be offered
on September 5 - 7, 2007 in San
Diego, California. For more details, see
http://Seminars.ReliaSoft.com/gencourses/rs560.htm. |

System Reliability/Maintainability Analysis Training
– This advanced training seminar is available only twice
a year in the USA, so start planning now if Reliability
Block Diagramming and/or Fault Tree Analysis techniques
are important
to you. Keep in mind, too, that the new
BlockSim 7
software will be used to help convey concepts, so you are
sure to get into to some fun and challenging coursework.
RS 522 - Advanced System Reliability/Maintainability Analysis
and BlockSim will be held September 17-19, 2007
in Tucson, Arizona. For more
details, see
