4. Electrical analogy and concepts of minimum closure and disconnection paths

4.1 Electrical analogy

The electrical analogy is introduced in the article [SE 4074] and leads us to consider the BDF equivalent to an ADD as an electrical circuit where the blocks are closed or open switches.

This is illustrated in figure 12, where working blocks are modelled as closed switches and faulty blocks as open switches. When the circuit is closed, the system is...
