Using Spreadsheets in RENO
ReliaSoft's
RENO
software tool is a platform for building and running
analyses for probabilistic or deterministic scenarios
using an intuitive flowchart modeling approach and
simulation. RENO can be thought of as a "visual
spreadsheet" that allows you to graphically create and
manipulate data and equations. However, RENO
also goes a step
further and provides the ability to manipulate internal
Excel®-compatible spreadsheets from the flowcharts. In
this article we will present an example using these
spreadsheets.

Reliability Basics |
Bounds on System Reliability
Information for reliability block diagrams often comes from a
mixture of sources, including in-house testing,
manufacturer data or reliability prediction methods. For
any component with information that comes from a manufacturer or
a reliability prediction, only the parameters (e.g. MTBF
for an exponential distribution or β and
η for a Weibull distribution) are available for
that component. Without the actual failure times that
were used to compute these parameters, it is impossible
to compute the variance of reliability for that
component. In order to compute bounds on system
reliability, it is necessary to know the expected value
and the variance of reliability for each component in
the system, so the bounds on system
reliability are not available in these cases. The bounds
on system reliability can be obtained, however, for the special case
where all the times-to-failure data for all the components
in the system are available. There are several
methods to compute these bounds. In this article we will
use a simple example to illustrate the method used in
Weibull++.To read more, see
