ReliaSoft's Alternate
Ranking Method
When analyzing interval
data, it is commonplace to assume that the actual failure time occurred
at the midpoint of the interval. To be more conservative, you can
use the starting point of the interval or you can use the end point of
the interval to be most optimistic.
Weibull++
allows you to employ ReliaSoft's ranking method (RRM) when analyzing
interval data.
Using
an iterative process, this
ranking method is an improvement over the standard ranking method (SRM).
This article presents
an example using the two-parameter Weibull distribution to illustrate
how this method is employed. This method can also be easily generalized
for additional models.

Relationship Between Availability and Reliability
Availability is defined as the probability that the system is
operating properly when it is requested for use. In other words,
availability is the probability that a system is not failed or
undergoing a repair action when it needs to be used. At first glance, it
might seem that if a system has a high availability then it should also
have a high reliability. However, this is not necessarily the case. This
article will explore the relationship between availability and
reliability and will also present some of the specified classifications
of availability.
