How can I get more information about the minimal cut sets for my
BlockSim diagram?
Minimal cut sets are all the
unique combinations of component failures that can cause system
failure. Beginning with version 7.0.7,
BlockSim offers
additional options for displaying minimal cut sets.
Choose Tools > Show Cut Sets.
The Cut Sets Settings window will appear, as shown next.
In the Sort by area,
select the criterion you want to sort the cut sets by. You can
select:
- Size: Cut sets will
be shown in ascending order based on the number of blocks
they contain.
- Reliability or
Unreliability: If you select either of these options,
you must specify a time at which the reliability or
unreliability is calculated. The cut sets will be shown in
ascending order of reliability or unreliability.
In the Number of Cut Sets to
Display area, you can select to display all cut sets or
specify the number of cut sets that will be shown.
In the Other Options
area, you can select the additional information that will appear
in the minimal cut sets display, including:
- Display Settings:
If selected, the Diagram name and a summary of the settings
chosen in the Cut Set Settings window will appear at the top
of the cut sets display.
- Display Number of
Blocks in Cut Sets: If selected, the number of blocks in
each cut set will be shown in parentheses after the set
number, as shown next.
You can change these settings
by clicking the Settings
button in the Cut Sets window toolbar to return to the Cut Sets Settings window.
How can I plot multiple items together in Lambda Predict 3? Can
I save my plots?
You can plot a single system or
block and all of its sub-items directly from the System
Hierarchy panel in
Lambda Predict 3 just click the item you want to use
as the top level item in the plot and then choose Tools >
Plot or click the Plot icon.
There may be other times
when you want to plot data for more than one system in a
prediction, or for just some of the blocks within a system. To create
a plot with multiple top level items, choose Project > Add
Plot or right-click the project's Stored Plots folder in the
Project Explorer and choose Add Plot on the shortcut menu
that appears. The Select Top Level Items to Plot window will
appear.
At the top of the window,
choose the prediction that you want to create the plot for. All
systems and blocks in the prediction will be displayed below.
Select one or more system(s) and/or block(s) to be used as the
top level item(s) in the plot.
You have
the option to save any of the plots that you create within
Lambda Predict, which allows you to keep the plots with the
project and return to them when needed. When working with plots
created from within the System Hierarchy panel, simply click the
Save icon.
When
working with a plot created from the Project Explorer, you will
automatically be prompted to save the plot.
Saved
plots will be accessible from the Stored Plots folder in the
Project Explorer.
After being saved for the first time, plots will be saved
automatically each time they are closed.
If you make changes to the
prediction associated with a plot, the plot will not reflect
those changes until it is refreshed. The plot status light in
the upper right-hand corner of the plot Control Panel will be
red in this case, indicating that the plot does not reflect the
current status of the items within it.
If you delete a prediction that
is referenced by a stored plot, the plot will remain available,
but you will not be able to make any changes to it.
