Diagrams

Analyses in BlockSim are based on two basic diagram types: reliability block diagrams (RBDs) and fault trees. These are both symbolic analytical logic techniques that can be applied to analyze system reliability and related characteristics. Either type can be configured as an analytical diagram (which uses the exact algebraic equation for the system model but imposes limitations on what can be modeled and what results can be obtained) or a simulation diagram (which provides more modeling options and results but must be analyzed with discrete event simulation).

To add a diagram to a project, choose Insert > Diagrams > [Diagram Type].

The topics in this section provide general information about the diagrams and the tools available for creating them, including:

Techniques for building diagrams.
Using the Block Properties window.
Configuring and using blocks in RBDs, including:
- A visual guide to the blocks available for use in RBDs.
- Diagram configurations and constraints.
- Detailed information on each of the block types.
Configuring and using blocks in fault trees, including:
- The relationship between RBDs and fault trees.
- A visual guide to the blocks available for use in fault trees.
- Diagram analysis constraints.
- Detailed information on each of the gate and event types.
Using blocks in more than one location through mirroring.
Viewing the details of the blocks and resources in the current diagram in the Block Details window.
Using the Item Properties Table to view and/or edit the properties of the blocks in the diagrams and the resources within the current project.
Building diagrams based on information from other Synthesis-enabled applications, including:
- Importing items from analyses in other Synthesis-enabled applications in the current project and creating either fault trees or RBDs that reflect the items' reliability-wise relationships.
- Creating a fault tree based on one or more effects in analyses performed in other Synthesis-enabled applications in the current project.
