It has to be noted that only the sequences (i.e. the MCSs) with
DIi;j–ø, for j = 1,2,. . .,NEi, remain. Moreover, even though in general
the quantification of the sequence probabilities is not the main
point in the present type of application, it can be added that the
probability of each individual basis event, P(Ek) = 1, if the basic
event has occurred, P(Ek) = 0, if it has not, while 0 < P(Ek) < 1 if it
is not possible to establish what has happened.
The previous formulae are useful for a general approach and can
be easily implemented in a software tool. In the following sections,
relevant to the case study, they will not formally applied, for the
sake of simplicity and for a more intuitive explanation.
