The present paper investigates the reliability analysis of industrial systems by using vague lambda-tau methodology in which information related to system components is uncertain and imprecise in nature. The uncertainties in the data are handled with the help of intuitionistic fuzzy set (IFS) theory rather than fuzzy set theory. Various reliability parameters are addressed for …

The present paper provides a model to this end, derived by extending the well known Reliability Block Diagram (RBD) method, currently used in the normal duties of a maintenance engineer. The usual RBD availability analysis is integrated by a state space analysis through which isolation times can be analysed.

Reliability Block Diagrams (RBD) Examples. If the reliability of each component in the series of three components is assumed to be 90%, then the system reliability would be 0.9 x 0.9 x 0.9 = 72.9%: In a system where the B function is designed with redundancy, and if both B functions must work, total reliability will not improve.

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. This method can be used in both the design and operational phase to identify poor reliability and provide targeted improvements.

Reliability block diagram. A reliability block diagram (RBD) is a diagrammatic method for showing how component reliability contributes to the success or failure of a redundant. RBD is also known as a dependence diagram (DD). An RBD is drawn as a series of blocks connected in parallel or series configuration. Parallel blocks indicate redundant ...
