Imperfect Repair
In
many cases, at the conclusion of a repair, preventive maintenance action or
inspection for a component, it is assumed that the component is returned to
an as good as new condition (or replacement). This means that the age of the
component is returned to time equals zero. However, this may not always be
the case. In fact, the age of the component after the repair may be a
percentage of its age at the time when the repair took place. BlockSim
6 allows you to specify a restoration factor, which is used to
determine the age of the component once the maintenance action has been completed.
This article will explore the concept of the restoration factor and how it
can be applied within BlockSim.

Design of Reliability Tests
In a past issue of the Reliability
Edge (see Cumulative
Binomial for Test Design and Analysis), an article was presented on the
cumulative binomial distribution and how it can be applied towards test
design. Given a specified reliability at a certain time along with a
desired confidence level, the required test units (given test time) can be determined to meet the
required goal. Calculating the required number of test units is fairly
straightforward if the test time is equal to the time at the reliability
goal. If this is not the case, then a failure distribution needs to be
assumed so that the calculations can be completed. This article
presents how this failure distribution can be applied to generate the
results using Weibull++
and illustrates the concept of allowable failures.

Tips |

-
How can I specify which icons are visible on the Data Folio Control
Panel in Weibull++?
-
Since temperature values must be entered into ALTA in absolute
scale, is there a way to automatically convert temperature values in
the Data Folio that are in Celsius and Fahrenheit to Kelvin or Rankine?
-
How can I find out about ReliaSoft's software validation and QA practices?
