Reliability Block Diagram (RBD) Modelling

What it is

Represent the system as a network of reliability blocks to show how individual failures and redundancies affect overall performance.

Why it matters

To visualize how architecture choices drive uptime and where the system is most vulnerable.

Benefits

• Identifies weak links and single points of failure
• Quantifies the real value of redundancy investments
• Supports defensible architecture and sparing decisions

When to engage

When reviewing system architecture, sparing philosophy, or backup configurations.

How Perennial Innovation delivers

PI builds and validates the RBD, runs configuration scenarios, and recommends architecture improvements that balance uptime against capital cost.
