The RBD is not a physical layout diagram of the system, but a logic diagram that shows how and when the system function, SF, is up. The sequence of failures is not important, and the RBD in Figure 2.10 is therefore equivalent to the RBD in Figure 2.11. The RBD shows the structure of the system with respect to a specified system function, SF. When discussing RBD, we talk about the structure instead of the system. Separate RBDs have to be established for each system function.
