Using the event tree shown in Figure 2 and the operational reliability of the fire protection systems, the occurrence probability of each fire scenario can be estimated.
Using the event tree shown in Figure 2, four probable fire scenarios can be determined from the event tree analysis.
Risk management/assessment methods allow determining the probability of the immediate roof collapse using the event tree
Plotted on probability-loss graphs, these distributions give us a more complete picture of the risk associated with a given exposure than merely plotting the outcomes of individual event tree branches.
An event tree such as the one shown in Figure 2 was used by a major manufacturer to prioritize disaster recovery plans for property exposures.
Basing on event tree
data, selective extraction 2 demonstrates better results than selective extraction 1.

The second half of the book covers the safety analysis of nuclear energy systems, an analysis of major accidents and incidents that occurred in commercial nuclear plants, applications of PRA techniques to the safety analysis of nuclear power plants (focusing on a major PRA study for five nuclear power plants), practical PRA examples, and emerging techniques in the structure of dynamic event trees
and fault trees that can provide a more realistic representation of complex sequences of events.
These three versions feature 12 tracks (48 variations) and two career event trees
, for a grand total of 66 events.
