In order to discern the expected reliability and availability The probability that a component or system is performing its required function at any given time. of the system, and the range of that behavior, we will run multiple realizations of the system using Monte Carlo simulation.
For this simple simulation, 100 realizations will provide a good sample to work with. To change the number of realizations, return to Edit Mode (press F4), and open the Simulation Settings dialog (press F2). Click on the Monte Carlo tab, and make sure the Probabilistic Simulation radio button is selected. Then change the # Realizations to 100:
Close the Simulation Settings dialog.
When running multiple realizations, in order to view time history results, you must connect the output of interest to a Time History Result element. To do so, right-click in the graphics pane The primary portion of the GoldSim interface, where the graphical depiction of the model is shown. and insert a Time History Result element A Result element that shows the history of a particular output as a function of time.:
The following dialog will appear:
Press the Add Result... button and select Component. Then close the dialog and run the model (by pressing F5).
