Tool Tips

* Can I schedule different components in a repairable system to undergo maintenance at the same time in BlockSim?
BlockSim allows you to coordinate maintenance actions among different blocks in your reliability block diagrams (RBDs), regardless of their relationships within the RBD. With the Item Group # option in the Maintenance tab of the Block Properties window, you can associate the maintenance actions of a block with those of one or more blocks in the same group. In the example shown next, Block A has been assigned to Item Group # 56.

Assigning any other block to group 56 will now link its maintenance actions to those of Block A. For example, if you want to perform preventive maintenance on Block G every time you perform corrective maintenance on Block A, assign Block G to group 56 in the Block Properties window. You can assign the Item Group # on the Corrective, Preventive or Inspection tab. Click the Preventive tab to assign a preventive maintenance policy to Block G. In this example, Preventive Policy 1 was selected. (If no preventive policy yet exists in the current project, you can click the Create New button to create one.) Click the View Selected button to open the policy window and select the Upon Maintenance of another Group Item option, as shown next.

You can select this option for an inspection policy as well, if desired.

Note that the default value for the Item Group # is 0, which is a reserved number and means that the item does not belong to any group.

* How can custom component data be reused in Lambda Predict?
In addition to using Lambda Predict's extensive collection of available parts libraries, you can also create your own parts libraries, enabling you to save the component data you enter and re-use components quickly and easily.

To create your own custom library, select New Library from the Library menu. The Library panel will appear in between the Project and System panels and the Data panel. In addition, the library will appear in the Project panel, indicated by a tab, as shown next.

You can build one or more systems, including blocks and components, in the Library Panel in the same way that you would build them in the System Panel. You can save the library by selecting Save Library from the Library menu. Specify the file name and location to save the library to in the window that appears. Libraries are saved as Lambda Predict Library (*.LPL) files.

The custom libraries that you build, like all of Lambda Predict's available libraries, can be accessed at any time by selecting Open Library from the Library menu. You can then copy and paste the pre-configured system elements in the library into your project. Libraries can also be loaded for background use via the Library Manager. All libraries that are currently open or loaded in the background are accessible from the Library Browse window, which allows you to browse for specific components and add them to systems or blocks in the System or Library panel. In addition, libraries that are open or loaded in the background are also searchable via the part number search feature in the Data Panel and the Import Wizard. For further information on using libraries, please see the Lambda Predict User's Guide or the online help included with the software.
