RBD Configurations and Constraints

BlockSim allows you to create an extensive array of RBD configurations. These can be as simple as units arranged in a pure series or parallel configuration. There can also be systems of combined series/parallel configurations or "complex" systems that cannot be decomposed into groups of series and parallel configurations. The supported configurations include:

In order to perform analysis, all RBDs created in BlockSim must conform to the following constraints:

If a diagram consists of only one block, that block represents both the starting and ending block. Starting and/or ending blocks that possess no reliability or maintenance characteristics can be defined by making sure no URD is assigned in the Block Properties window. This indicates that the block cannot fail and that the reliability of the component at all times is considered to be 1 or 100%.
