Given the diagram, determine the system reliability if the individual component reliabilities are:
A = 0.94,
B = 0.92,
C = 0.97, and
D = 0.95.
The reliability system that you have been given is a mixture of a series designed system with an active parallel system. In other words, while A and B together make an active parallel system, and C and D make their own, separate, active parallel system, these two individual active parallel systems are together placed in a series designed system.
What does this mean? To put it simply, an active parallel system, such as the one composed of A and B, allows for either component to carry the full workload of the system should the other one fail. ...
