Reliability Block Diagram (RBD) Generator

Build an RBD from a simple table, visualize the hierarchy, and compute overall system reliability.

Import CSV

1) Input Table

Columns (in order): Component Name, Type (Block, Series, Parallel), Parent (blank for root), Reliability (0–1, only for Block).

Overall System Reliability (root):—

Computed from the root node (blank Parent). Series: product of children. Parallel: 1 − Π(1 − rᵢ).

Click Generate to compute and display node reliabilities.

Click Generate to render the diagram.

Component Name is case-sensitive and must be unique.
Type must be exactly one of: Block, Series, Parallel.
Parent is blank for the top-level system (root); otherwise, it must exactly match an existing name.
Reliability is required only for Block (0–1). Leave blank (or 0) for Series/Parallel; those are computed from children.
Exactly one row must have a blank Parent (the root). All nodes must be reachable from the root. No cycles allowed.
