Options for Block Items
To view settings for the components in a selected design or subsystem in the Repairable Systems Simulation platform, do the following:
• To view the Configuration settings for a block shape, select the block shape in the System Diagram.
• To view Configuration settings for more than one block shape, select multiple block shapes using the Arrow tool, press Ctrl, and click multiple block shapes.
Distribution Options
Each block shape in the Repairable Systems Simulation platform randomly fails according to the type of block and its specified failure distribution. For block shapes other than Basic, the failure distribution is specified for the subcomponents of the block. In addition, you specify a time unit for the distribution. The time unit for a block shape can differ from the time unit option that you specify in the simulation settings. The Turn On Count option is based on the number of times the individual block shape has been set to the On state.
The available failure distributions are listed in Table 13.2.
