Software Reliability Block Diagram. Relyences reliability block diagram software is a powerful platform for system modeling including complex systems incorporating redundancy. RBD is also known as a dependence diagram DD.
A Reliability Block Diagram RBD is a graphical representation of the components of the system and how they are reliability-wise related. It is not necessarily the schematic diagram of the equipment but the functional. The diagram represents the functioning state ie success or failure of the system in terms of the functioning states of its components.
This method can be used in both the design and operational phase to identify poor reliability and provide targeted improvements.
RBD is also known as a dependence diagram DD. The Reliability Block Diagram is a graphical methodology to describe a system in an intuitive way to represent the schematics of a system decomposing it into various sub-systems components or functions. The Reliability Block Diagram RBD is used to identify potential areas of poor reliability and where improvements can be made to lower the failure rates for the equipment. A Reliability Block Diagram RBD is a method of modeling how components and sub-system failures combine to cause system failure.
