Phase Diagrams
A phase diagram, or more specifically a reliability phase diagram, is an extension of the reliability block diagram (RBD) approach. While an RBD is used for a system with a fixed configuration throughout the entire period of operation, a phase diagram can be used to represent scenarios in which a system may undergo changes over time to one or more of the following:
- Its reliability configuration
- The available repair resources
- The failure, maintenance or throughput properties of its individual components.
For example, a manufacturing company's production may be lower during the night shift than during the day shift. Or a system may use different components during different stages of operation, such as an aircraft during taxiing, takeoff, cruising and landing. In these and many other situations, a phase diagram can be configured so that the simulation will account for the differences in the system during different time periods.
