Modeling a Complex Maintenance
Scenario in BlockSim
Many organizations use
BlockSim to model and simulate repairable
systems in order to obtain estimates of reliability, availability, number
of spares required, maintenance cost, throughput and other
related metrics for a given mission time. The numerous features
available in BlockSim’s reliability block diagrams and phase
diagrams make it the software of choice for advanced system
analysis. However, at times the reliability analyst may come
across scenarios that at first seem beyond BlockSim’s
modeling capabilities. This article discusses one such scenario
and gives the solution to implement it in BlockSim.

Maintenance Policies in
BlockSim
BlockSim
includes a number of maintenance policies to model corrective,
preventive and inspection activities on repairable systems so
that the operation and maintenance of systems can be simulated
as accurately as possible. This article discusses two of these
policies: "Corrective maintenance upon inspection" and
"Maintenance of an item upon the maintenance of another group
item." The implementation of these policies in BlockSim
is illustrated using simple examples. These policies also can be
combined to model other complex maintenance procedures, such as
the scenario described in this
month's
Hot Topics article.

Special Congratulations to Award Recipients -
At the 2008 International Applied Reliability Symposium, North America, we had the privilege of
presenting the following awards:
2008 Reliability
Leadership Award - presented to two companies, Seagate Technology and Delphi Thermal,
in order to recognize their efforts in the area of Design for Reliability (DFR). Both companies
understood the need for knowledgeable engineers to drive the DFR process and implemented
corporate-wide training programs to accomplish this goal.
2008 ARS Excellent
Presentation Awards - presented to individuals for
the presentations they gave at ARS, based on votes from
their peers attending the event:
* Gold ($1000): Stephanie Hahn,
Cessna Aircraft Company, "Program Managing for
Reliability During Development of Cessna Citation
Mustang"
* Silver ($750): Jerry Roslund, GLR Consulting, "Using the
Weibull Function to Validate Product Life"
* Bronze ($500): Harland MacKenzie, Dana Corporation, "The
Pitfalls of Accelerated Life Testing"
Details and some
pictures related to the awards presented this year are
available on-line at:

reliability and life data analysis and serves as the
cornerstone for all subsequent MSMT courses. The next
two sessions provide introductions to quantitative
accelerated life testing (QALT) data analysis and system
reliability/maintainability analysis.
Detailed course
outlines for each session are available online at:
