The control panel associated with BlockSim phase diagrams consists of multiple pages, each containing options for performing particular tasks. This topic focuses on the Simulation page and Analysis Settings page of the phase diagram control panel, which contain most of the tools you will need to simulate a diagram. For more information about the control panel in general, see Control Panels.
The Simulation page of the control panel for phase diagrams contains the following options:
The Simulation area displays the status and results of the simulation.
Status If the light is green, then the simulation has been performed. If the light is red, then the simulation has not been performed. A simulated diagram will remain in the simulated state unless a change is made to the structure of the diagram (e.g., a block is added, a connector is removed, etc.).
Show Simulation Details (...) displays the most recently generated simulation results in the Results Explorer.
Distribution fit displays the distribution that has been fitted to the simulation results. Click the button (...) to open the Distribution Estimator to fit a distribution and/or for information on the fitted distribution parameters. The fitted distribution can be used to describe the overall behavior of the system and can be published for use as a model elsewhere in the project.
The Information area displays information about the diagram or the currently selected block. If no block is selected in the diagram, the Information area displays the number of operational phase and maintenance phase blocks in the diagram, the total duration of all phases in the diagram and information about the diagram creation and last modification. If a block is selected in the diagram, it displays a subset of the properties found in the Block Properties window. In both cases, this area also offers a Comments field; click the field heading to enter comments. For blocks, these comments are also accessible in the Identifiers properties in the Block Properties window.
The Tools area on the left side of the control panel gives you quick access to the tools you will need to analyze the diagram and generate additional results.
Simulate opens the Maintainability/Availability Simulation window, which allows you to obtain reliability, maintainability, availability and throughput results from simulations.
Plot creates a plot based on the simulation results. Clicking the Plot icon before the diagram has been simulated will automatically perform the simulation and then plot the data.
Simulation QCP opens the simulation Quick Calculation Pad (QCP). The QCP allows you to obtain reliability, maintainability and availability metrics based on the simulation results. Clicking the QCP icon before the diagram has been simulated will automatically perform the simulation and then open the QCP.
The Analysis Settings page of the control panel for phase diagrams contains the following options:
Analysis Settings
Select Report subdiagram results to provide calculated results for subdiagram blocks in the Results Explorer and certain plots. If this check box is not selected, subdiagram blocks will not appear in the results.
Use system downtime threshold allows you to specify a minimum amount of time that the system must be down in order for it to count toward critical downtime metrics.
Select Run throughput simulation to perform the throughput simulation, which allows you to perform analyses on the number of units that can be processed by the system in the diagram during the simulation time. If you select to run a throughput simulation, you can select Report throughput point results to include throughput results in the System Point Results worksheet, which provides results at specified points in time. If this check box is not selected, only the throughput results for the system at the simulation end time will be reported.
Report Settings
Report folio model allows you to specify the results model that will be used when the diagram is used as the default data source for a Synthesis Workbook. You can choose to use either the simulation results or the fitted model.
Max RDA data allows you to specify the maximum number of events that can be shown in the RDA Data worksheet in the Results Explorer. The contents of the RDA Data worksheet can be transferred to a parametric RDA folio in Weibull++ for further analysis.
System Level Costs
Cost per System Failure allows you to specify a failure cost per incident at the system level (i.e., an additional cost that is not accounted for by any of the block level costs).
System Downtime Rate allows you to specify a cost per unit time for downtime at the system level (i.e., an additional cost that is not accounted for by any of the block level costs).
System Level Revenue
Revenue per [Unit] of Uptime allows you to specify an amount of revenue that is brought in by the system for each unit of uptime. This can then be accounted for as a loss when the system is down.
Revenue per Unit Produced allows you to specify an amount of revenue that is brought in for each unit produced. This can then be accounted for as a loss when the system is down. This option is available only when you have selected the Run throughput simulation option in the Analysis Settings area of this control panel page.
