New Features in RGA 7 for Reliability Growth Analysis
and Fielded Repairable System Analysis
RGA 7 has just been released and
the software is
packed with new features to support more powerful
applications for reliability growth models in
developmental testing and fielded repairable systems.
In this article, we present a brief overview of some of the most exciting new
features in RGA 7.

Reliability Basics |
Median Rank Based on Mean Order Number
In a probability plot such as the
Weibull probability plot, the points represent the
"observed unreliabilities," while the straight line
represents the predicted values from a model. However,
one cannot observe an unreliability value; only
failures or suspensions can be observed. Reliability or
unreliability values must be estimated from the data.
Rank methods determine the way the estimated unreliabilities are associated with the failure times.
The median rank method, which is used in
Weibull++,
estimates unreliability values based on the failure
order number and the cumulative binomial distribution.
To accommodate suspension data, it is necessary to
adjust the order of each failure. In this article,
we will provide step-by-step methods to
calculate the median rank using the adjusted failure
order number (mean order number).
