Using Simulation RBDs
A reliability
block diagram (RBD) is a graphical representation of how the
components of a system are reliability-wise connected. BlockSim's
RBDs can be configured as analytical
diagrams (which use the exact algebraic equation for the system
model but impose limitations on what can be modeled and what results
can be obtained) or simulation
diagrams (which provide more modeling options and results
but must be analyzed with discrete event simulation).
The basic steps for using a simulation RBD are:
- Add diagram
Right-click the RBDs folder in the current project explorer
and choose Add Simulation
RBD.
- Add blocks
Right-click inside the diagram and choose the type of
block to add.
(See RBD Block Types.)
- Connect blocks
Hold down the ALT
key, click the source block and drag a line to the destination
block.
- Set block properties
To edit a block's properties, right-click it and choose
Block Properties.
Use a universal reliability
definition (URD) to specify the reliability properties.
(See Creating
and Selecting Resources.)
- To select an existing URD, click inside the
URD field.
- To create a new URD, click inside the Model - Reliability
field and follow the wizard. You can create a new
model (left) or select an existing model (right).
Existing models may have been manually created, or
may have been published
from other analyses in BlockSim, Weibull++ or
Lambda Predict.
- Simulate the diagram
- View the simulation results
From within the Maintainability/Availability Simulation
window, click Details.
If you have closed the window, click the Results
valid as of field on the control panel.
(See Results Explorer
for available results.)
- Calculate metrics
Click the QCP
icon on the control panel to open the Quick Calculation
Pad.
(See Simulation
QCP
for available calculations.)
- View plots
Click the Plot
icon on the control panel to open the plot sheet. (See
Simulation Plots
for available plot types.)
