Equation
Notation
The probability of failure
is the number of failures of edge ; is the total operating time of edge .
Fault propagation probability
is the number of shortest paths crossing a given edge .
Connection strength
is the number of times that operation states change in the statistical time; indicates the number of times that operation states change arising from in the statistical time; is an empirical contact duration of the type of functional dependencies between components and .
